In a Nutshell

What makes crypto slot games fun?

There’s no learning curve. Plus, slots come in different themes and with different gameplays for more fun options.

What is RTP (Return to Player)?

RTP is a percentage that shows how much a slot machine is expected to pay back to players over time.

What is volatility in slot games?

Volatility refers to the risk level of a slot game. High volatility slots have bigger wins but less frequent payouts, while low volatility slots offer more frequent, smaller wins.

What are the most common features in crypto slots?

Common features in crypto slots include free spins, multipliers, wilds, scatters, and bonus rounds.

What are the minimum and maximum bets in crypto slot games?

The minimum and maximum bets in crypto slots vary depending on the game, from $$0.1 to $500 per spin.

How do slots work?

Slot games work by letting you place a bet and then spinning the reels. The random number generator (RNG) picks a result for each spin, which determines if you’ve won or lost. When the symbols line up on the paylines, you win a payout based on the combination.

How paylines work in crypto slots

A payline is a line on the slot grid that determines if you win based on the symbols that land. In most slots, these lines run from the left-most reel to the right-most reel, but some slots can have vertical, horizontal, or diagonal lines.

To win, you usually need at least three matching symbols on a payline. Modern slots can have anywhere from 10 to 50 paylines, and the more paylines there are, the more chances you have to win.

As for the symbols, there are no rules here, it depends on the game. But, there are regular symbols and premium symbols. Regular ones are basic symbols that only pay a certain amount, for example, cherries or grapes in a fruit-themed slot game.

Premium symbols are the ones that give way better payouts and usually have some mechanics attached to them. For example, a ‘’7’’ symbol is usually the one that gives up to 500x your bet. In some slot games, ‘’7’’ acts as a wild symbol as well.

Now, imagine you’re playing a slot with 20 paylines and a premium symbol worth 200x. If you get five of these symbols on one payline, you win 200x your bet. But if you fill all 20 paylines with these symbols, your payout could be 4,000x.

Some slots have fixed paylines, meaning all lines are always active, while others offer adjustable paylines - this gives you more flexibility to bet on fewer lines, which can lower your overall bet size. The more paylines you activate, the more chances you have to win - but it also means a higher cost per spin.

RTP (return to player) explained

RTP stands for Return to Player and is the percentage of total money wagered that a slot game is expected to pay back to players over time.

Let’s look at it this way - a game with an RTP of 98% means that, on average, the game will return $98 for every $100 wagered by all players, not just you. It’s important to remember that this is based on thousands of plays, not one individual’s experience.

So, if a slot has an RTP of 98%, it doesn’t mean you’ll get $98 back from your $100 bet.

RTP is calculated over a large number of spins - usually 10,000 or more - which means it’s an average over time. This doesn’t guarantee that you’ll get the same percentage in one or even 100 sessions.

The industry average for slots is around 95%, but there are games that offer 99% (Mega Joker by Netent) and those that have 92% RTP (Dazzling 7 by Inbet Games).

RTP is a standalone metric in slot games, so it’s not connected to any other mechanic, such as paylines, volatility, etc.

Example

Let’s take a look at the Hot Chilli Bells by BGaming - I found it on Betplay Casino, and I’ll show you a bit more about paylines with this slot.

Now, as you can see, you can adjust the number of lines on the right-hand side, from 20 to 100. But, notice that the minimum bet also changes, from $0.2 to $1, as you progress.

Let’s play using 60 paylines.

Now, this is good because there are more frequent wins, but the payouts are slim. I got six watermelon symbols spread across the reels, and the machine connected them using these lines. So, with a $0.6 bet, I got a $0.7 payout.

The role of volatility in slot games

Volatility in slot machines refers to the level of risk involved with playing a particular game. It essentially measures how often a slot pays out and how large those payouts tend to be. So, the volatility level can influence your overall experience, from the frequency of wins to the size of those wins.

All slot games can be divided into different volatility categories - high, medium, and low - each affecting your gameplay in different ways.

To start, high-volatility slots offer big payouts, but they're less frequent, meaning you may have to wait a while for a win. On the other hand, low-volatility slots deliver smaller wins more often, which can be great if you're looking for a steady flow of action.

Slot machines explained - understanding mechanics and features

Slots may seem simple at first glance, but there’s a lot going on behind the reels. I’ll now break down the key features you’ll encounter, explained in a way that’s easy to grasp, even if you’re new to slots.

Reels

Reels are the vertical columns where the symbols spin. Traditionally, slot games had three reels, but today’s video slots often have five, six, or even more. Some games include special features like cascading reels, where symbols fall into place and disappear after a win, making room for new ones.

One good example of cascading reels is offered by Gates of Olympus 1000 slot game.

Other features, like “locked reels” or “wild reels,” can boost your winning potential. One unique option is the "reel hold" feature, where you can choose to freeze a reel for your next spin.

Wilds

Wild symbols are like jokers in a card game - they substitute for other symbols to help you complete winning combinations. In some games, wilds do even more, like in Starburst where they expand on a while reel and connect symbols to an adjacent reel. Here’s how that looks in this game.

You might see expanding wilds that grow to fill an entire reel, sticky wilds that stay in place for several spins, or multiplying wilds that increase your payouts.

This symbol is quite popular among players because it improves your chances of winning in some cases. And, it’s just fun to see how the wild symbol works.

Free spins

Free spins are one of the most popular features in slot games - it’s what slots are known for. Essentially, you get a set number of spins without spending your own money. These are usually triggered by landing a specific combination of symbols, like scatters - that’s a symbol that works only to provide free spins.

During free spins, you might also unlock extra bonuses, like multipliers or additional spins. Any winnings you collect during the free spins sessions get added to your total, so it's no wonder people love them so much.

One good example of free spins can be found in the Book of Ra deluxe slot game. I played it on Wild.io and all I had to do was land three book symbols to unlock 10 free spins.

Jackpots

Jackpots are the ultimate prize in slot games - there’s simply no other way to explain it. A standard jackpot pays out a fixed amount when you hit the right combination. But progressive jackpots are where things get really exciting - they pool contributions from multiple players, growing until someone wins.

Winning a progressive jackpot can turn a small bet into a life-changing payout, but you’ll usually need to bet big ($5 to $50 per hand) to qualify. It’s high-risk, high reward, but that’s part of the thrill.

Let’s take a look at Wolf Gold slot on Crypto Games Casino. I set the bet on $5 and the fixed jackpot is clearly displayed on top. Ranging from $150 to $5,000, I only have to land 3 or more Moon Symbols for the Mini jackpot and a full screen for the Mega jackpot.

How do bonus rounds work?

First of all, don’t mistake bonus rounds for free spins. Free spins are only one of the several types of bonus rounds.

Bonus rounds are triggered in different ways depending on the game, but they all share the same goal: to keep you playing longer.

To activate a bonus round, you’ll typically need to land a specific combination of symbols, like three Scatter symbols or certain special icons. These requirements vary by game, so it’s always a good idea to check the slot’s rules and payout table for details.

Once you trigger the bonus, you’ll get to participate in a mini-game or extra round, where the stakes - and the fun - are usually higher.

Here are the types of bonus rounds:

Free spins

As said earlier, you get a set number of spins without spending your own funds, but you still keep all the winnings. Free spins are often triggered by landing three or more Scatter symbols.

Some games add extra perks during free spins, like multipliers or additional bonus symbols, to make the round even more rewarding.

Bonus games

Bonus games take you into a new, interactive scenario. You might open treasure chests, pick hidden items, or match cards. These rounds are designed to be engaging and fun while giving you a shot at extra rewards.

The goal is to maximize your winnings or unlock more features. So, this is actually something like ‘’upgraded’’ free spins.

Expanding symbols

During some bonus rounds, specific symbols can expand to cover entire reels. This increases your chances of forming winning combinations, as the expanded symbols take up more space.

Multipliers

Multipliers increase your winnings by a specific number, like 2x, 3x, or even more. For example, if you win 100 coins and there’s a 5x multiplier, you’ll walk away with 500 coins. Multipliers often appear in conjunction with other bonus features, supercharging your rewards.

Tips for slots: how to play with confidence

Slots are all about luck and randomness, so it’s important to start with this reminder: just because you’ve lost 100 spins doesn’t mean you’re due for a win. Every spin is independent of the last.

Responsible gambling should always be your priority - set limits, play for fun, and know when to stop.

That being said, let’s see some tips to make your slot session better, not necessarily to win more (there are no tips or tricks for that, I'm afraid).

Maximize your bankroll

Use promotions, loyalty programs, and bonuses to stretch your bankroll. These extras can give you more playing time and opportunities to win, while casino rewards often include perks like free drinks at the land-based facilities or some merch.

Split your bankroll

Break your total budget into smaller portions for individual sessions. This helps you manage your money better and avoid overspending in one go.

Bet maximum when possible

Betting the maximum coin size can unlock larger payouts and progressive jackpots. This strategy works best if it fits comfortably within your budget.

Find slots with high RTP

Research which games offer better odds and play those with the lowest house edge. A little homework can go a long way in improving your chances.

Play all paylines

Modern slots often feature multiple paylines, sometimes as many as 50. Activate all of them to increase your chances of hitting a winning combination.

Take breaks

Set time limits for your sessions and step away when your timer is up. Use breaks to grab a meal, watch a show, or relax, keeping your gambling experience balanced.

Set win limits

Know when to walk away. Decide in advance how much of your winnings you’ll keep and resist the temptation to keep playing and risk losing it all.

Have fun

At the end of the day, slots are meant to be entertaining. Don’t take it too seriously, and remember to enjoy the experience. If luck isn’t on your side, come back another time.

Is there a trick to playing slots?

By now, you must be wondering: how do you even win a slot game? Well, unsurprisingly, there’s no bulletproof tactic.

But, if you’re looking to improve your approach and make your sessions a tiny bit better in terms of payout, there are strategies that can help. Here are a few tips and tricks to consider:

Practice in demo mode

Before getting into real money slots, try playing free versions first. It’s a fun way to understand the mechanics of the game, learn about bonus rounds, and spot quirks without risking your bankroll.

Aim for smaller jackpots

Slots with smaller jackpots often have better payout frequencies. While progressive jackpots are tempting, they can be harder to win. If you’re focused on steady, smaller wins, these games might be your best bet.

Levels betting

Start with a bet size that’s 1% of your bankroll. After five consecutive losses, increase your bet size in increments of five units. For example, if you start betting $1, move to $5, then $10, and so on.

Reset to the base bet after a win. This approach aims to recover losses with larger payouts, but can be risky if you hit a long losing streak.

Fixed percentage betting

Bet a set percentage of your available bankroll, such as 3%. Adjust the bet size as your balance changes. For example, if you start with $100, your initial bet would be $3. If your balance increases to $110, your next bet would be $3.30.

This method limits losses during bad runs and maximizes gains during hot streaks, though it requires paying close attention to calculations.

Top crypto slot games to try

I’ve played a ton of crypto slot games, and let me tell you, some just hit differently. Of course, which ones stand out depends on your preferences - do you love flashy themes, and big jackpots, or is innovative gameplay your non-negotiable? But after plenty of spins, I’ve found 10 gems that deserve a mention either way.

Wanted Dead or a Wild

Wanted Dead or a Wild by Hacksaw Gaming delivers a gritty, dark Wild West adventure with striking visuals and a unique soundtrack. The 5x5 grid with 15 paylines provides plenty of action, but the game’s high volatility ensures you’re in for a fun, high-risk ride.

The bleak visuals, blood-red sky, and somber soundtrack create an immersive experience. That’s why this slot game stands out from other Western-themed slots. I enjoyed it in BitStarz Casino and the feeling was quite good, especially when I triggered free spins.

The RTP varies depending on the casino, so always check before playing, but the maximum is 96.38%, with a hit rate of 19.36%, meaning roughly 1 in 5 spins could land a win.

Key stats:

Feature	Details
Reels and Paylines	5x5 grid, 15 paylines
RTP	Up to 96.38%
Volatility	High
Max Win	12,500x your stake
Bet Range	$0.20 to $100 per spin

The game features expanding multiplier wilds, sticky wilds, and three bonus rounds, each with its own unique mechanics.

One of such symbols is the VS symbol. This special symbol expands to cover the entire reel, turning into a wild. It triggers a gunslinger duel awarding a random multiplier from 2x to 100x. If multiple VS symbols contribute to a win, their multipliers are added.

Another thing worth mentioning is wild symbols. These substitute for all regular symbols, helping to complete winning combinations. Alongside the pistol cylinder symbol, wilds are the most valuable, paying 20x your stake for five on a line.

Now, let’s talk about bonus rounds, which are the highlight of this slot game.

The great train robbery

This feature is triggered when you land three or more Train Robbery symbols on the reels. Once activated, you receive 10 free spins, where every wild symbol that appears sticks to the reels for the duration of the round.

The sticky wilds can help you form consistent winning combinations, making this bonus less volatile than the others. While the potential payouts are smaller, the medium volatility makes it a great choice for players who prefer a more steady gameplay experience.

Duel at dawn

The duel at dawn bonus round begins when you land three or more Duel symbols in a single spin. This round also awards 10 free spins, but it cranks up the excitement with a higher chance of landing VS symbols, which can combine for massive payouts.

However, this feature comes with high volatility, meaning big wins are possible, but the frequency of smaller payouts is much lower. It’s perfect for those who enjoy high-risk, high-reward gameplay.

Dead man’s hand

This bonus round stands out due to its two-phase structure. It starts with the Collect Phase, where you aim to gather as many wilds and multipliers as possible through a streak respins mechanic. You have three spins, and every collected symbol resets the spin count. When no symbols land for three spins, the Showdown Phase begins.

In the Showdown Phase, the collected wilds are randomly distributed across the reels for three spins, and every win is boosted by the accumulated multiplier, which can go up to 31x.

Big Bass Bonanza

Big Bass Bonanza by Reel Kingdom is a slot that takes players on a fishing adventure with fast gameplay and charming visuals. The game unfolds on a 5x3 reel grid with 10 paylines, where players can form winning combinations by landing matching symbols on adjacent reels, starting from the leftmost one.

With medium-to-high volatility and the maximum payout of 2,100x your stake, it is quite tempting to hit the spin button.

The RTP is up to 96.71%, but this varies depending on the casino, so it’s always best to confirm it before playing. I played it on the Cloudbet iGaming site and I liked how fast and easy everything was. Plus, the visuals and sound effects are quite impressive.

Key stats:

Feature	Details
Reels and Paylines	5x3 grid, 10 paylines
RTP	Up to 96.71%
Volatility	Medium to high
Max Win	2,100x your stake
Bet Range	$0.10 to $250 per spin

Now, let’s talk about symbols and features that you can encounter in the Big Bass Bonanza slot game.

Scatter symbol

The scatter symbol is your gateway to free spins. Landing 3, 4, or 5 scatter symbols will award 10, 15, or 20 free spins, respectively. Unlike its sequels, there’s no bonus buy option in the original Big Bass Bonanza, so triggering the free spins is your only route to the bonus round.

Money symbol

The fish symbols serve as money symbols, each displaying a random cash value that can range from 2x to a massive 2,000x your bet. These values are collected during the bonus round, adding significant excitement to the gameplay.

Wild symbol

During the free spins, the fisherman wild symbol comes into play. It acts as a substitute for all other symbols and has a unique function: when a wild lands with fish money symbols, it collects all visible cash values.

Free spins and multipliers

Free spins are the heart of Big Bass Bonanza. Each wild collected during the game is stored in a meter, and every 4 wilds retriggers the feature with an additional 10 free spins and an increased multiplier.

The wild multiplier progresses to:

2x for the first retrigger
3x for the second retrigger
10x for the third retrigger

Once the final stage is reached, no further retriggers are possible. If you hit the 2,100x max win during the bonus, the round ends immediately.

Cash The Gold

If you love dazzling and glittering symbols, Cash the Gold by 1spin4win should be your number one pick. This slot revolves entirely around cash and gold, combining simplicity with a touch of luxury. While the visuals might feel a bit dated at first glance, the gameplay offers enough fun to keep you spinning.

The game unfolds on a classic 5x3 reel setup, with payouts awarded for landing three identical coins, anywhere on the lines. Unlike many modern slots, Cash the Gold sticks to straightforward mechanics. Buttet game’s standout feature is its coin-based wins: each coin holds a multiplier value between 1x and 100x, and this offers a mix of smaller wins and potentially big payouts.

The game comes with an RTP of 97%, slightly above the industry average. I enjoyed this game on BC.Game Casino and it’s enough to say that this is the most straightforward slot I played.

Key stats:

Feature	Details
Reels and Paylines	5x3 grid, no paylines
RTP	97%
Volatility	Medium to High
Max Win	2,500x your stake
Bet Range	1 to 30 coins
Special Symbols	Wild symbols, Free Spins coins
Bonus Features	Gamble feature, Spin Chance

Now, this slot offers only one feature - Gamble. If you land a win worth 5x your total bet or more, you can choose to gamble it. The feature offers two wheels - one to multiply your winnings, and another to earn you more free spins. However, the risk is real: a red section on the wheel means you lose your winnings and return to the base game.

Starburst

Starburst, developed by NetEnt, is one of the most iconic online slot games. Why? Well, it’s mostly because of its vibrant visuals and simple yet engaging gameplay. And, this slot is perfect for those who love a retro, arcade-like vibe.

The game features 3D-like graphics with dazzling gems in various colors, along with classic lucky sevens and bar symbols. The sound effects and background music elevate the experience even more. My go-to place for this game is FortuneJack.

Starburst is played on a 5x3 grid with 10 paylines, which pay in both directions, increasing your chances of winning. Its low volatility ensures frequent payouts. The game has an RTP of 96.1%.

Key stats

Feature	Details
Reels and Paylines	5x3 grid, 10 paylines (both ways)
RTP	96.10%
Volatility	Low
Max Win	250x your line bet
Bet Range	$0.10 to $100 per spin
Bonus Features	Expanding Wilds, up to 5 re-spins

As for the special symbols and features, Starburst is stacked with wilds and re-spins.

The standout feature in Starburst is the wild bonus round. The wild symbols can only appear on reels 2, 3, and 4. When a wild lands, it expands to cover the entire reel and triggers a re-spin. If another wild appears during the re-spin, the feature continues, allowing up to 5 re-spins in total.

While Starburst doesn’t offer a progressive jackpot, its top prize is 250x your line bet. The absence of traditional free spins is compensated for by the frequent re-spins from the wild feature, which can be quite rewarding.

Chilli Heat

Chilli Heat, by Pragmatic Play, brings the lively spirit of Mexico to your screen with crisp visuals, mariachi music, and lots of features. This cheerful game combines a medium volatility level with balanced bonus mechanics.

Set against the backdrop of a Mexican street lined with cactuses and colorful houses, Chilli Heat features a 5x3 grid with 25 paylines. The betting range accommodates all types of players, starting at $0.25 and going up to $125 per spin.

The standout elements of Chilli Heat are its money respins feature and free spins bonus round. The game also boasts three fixed jackpots, including:

Jackpot Type	Multiplier
Grande Jackpot	1,000x your stake
Major Jackpot	100x your stake
Mini Jackpot	30x your stake

With an RTP of 96.5%, it offers decent returns while keeping things entertaining. I enjoyed this game on Justbit.

Key stats:

Feature	Details
Reels and Paylines	5x3 grid, 25 paylines
RTP	96.50%
Volatility	Medium
Max Win	1,000x your stake
Bet Range	$0.25 to $125 per spin
Bonus Features	Money Respins, Free Spins, Wilds
Jackpots	3 Fixed Jackpots

Now, let’s see a bit more about those features.

Money respins feature

Triggered by landing 6+ money bag symbols, this feature uses a new reel set where the triggering symbols become sticky. You start with 3 respins, and every new money bag resets the counter. Filling all 15 positions with money bags not only awards their combined value but also grants the Grande Jackpot.

Free spins bonus round

Land 3 sunshine scatter symbols on reels 2, 3, and 4 to unlock 8 free spins. During this round, only high-value symbols appear, boosting your chances of hitting big wins. The feature can be retriggered endlessly by landing additional scatters.

Wild symbol

The Chilli Heat logo acts as the wild, substituting for all regular symbols to maximize winning combinations. It doesn’t replace scatters or money bags, though.

The maximum win in Chilli Heat is capped at 1,000x your stake, achievable through the Grande Jackpot.

Queen of the Pyramids Mega Cash Collect

When it comes to visually stunning graphics, Playtech did a really good job with the Queen of the Pyramids Mega Cash Collect slot. This game takes you back to the era of Cleopatra, combining exciting features for fast-paced gameplay. The game is part of Playtech’s popular Cash Collect series, known for its unique mechanics and engaging gameplay.

The design is top-notch, with high-quality graphics, lively animations, and an ancient Egyptian vibe. The reel setup is a bit unusual, featuring a 3-4-4-4-3 grid and 30 fixed paylines. The betting range is flexible, starting at $0.10 and going up to $500 per spin, appealing to both casual players and high rollers.

While the RTP stands at 95.41%, the unique features and variety of mechanics make this slot a solid choice for fans of Egyptian-themed games. I made my deposit on Blizz Casino and enjoyed this game there. Lady Luck was on my side and so I landed a full reel of wilds on the second and fourth reel.

This slot is also equipped with four fixed-prize jackpots that vary depending on your wager. I usually bet with $10, so for me, the jackpots are:

Jackpot Type	Multiplier
Grand	500x
Major	200x
Minor	50x
Mini	20x

Key stats:

Feature	Details
Reels and Paylines	3-4-4-4-3 grid, 30 fixed paylines
RTP	95.41%
Volatility	Medium
Max Win	Up to 16x per Sticky Cash symbol or Jackpot Diamond wins
Bet Range	$0.10 to $500 per spin
Bonus Features	Dropping Wilds, Cash Spreader, Sticky Cash, Jackpot Diamonds, Cash Collect mechanic

In terms of gameplay, Queen of the Pyramids has plenty of features to keep things interesting. It introduces cash-collect symbols that work with key symbols to unlock extra reels, where special perks await.

Dropping wild:

A stack of wild symbols drops onto the main reels, with multipliers increasing up to 3x when combined with multiple cash-collect symbols.

Cash spreader:

The Pharaoh staff symbol adds coins to random positions and transforms them into a random coin itself.

Sticky cash:

Sticky symbols stay on the reels, doubling their value each spin when cash collect symbols are present, and can turn into jackpot Diamonds worth up to 16x the stake.

Sahara Riches Cash Collect

Again, Playtech outdid itself with this Arabian adventure. This medium-volatility slot brings players a mix of cash-collecting mechanics, free spins, and jackpots, though it may not appeal to high rollers due to its modest max win of 500x your stake.

The game’s visuals are appealing, with a classic Arabian theme brought to life through rich graphics and smooth animations. The reels are filled with symbols like treasure chests, gold coins, and the Arabian lady, who serves as the Wild.

You’ll spin on a 5x3 grid with 30 fixed paylines. Winning combinations form by landing matching symbols, starting from the leftmost reel. With a betting range from $0.10 to $500, the game is accessible to a wide range of players, though its low max payout may deter those chasing bigger wins. My go-to place for this slot is 7Bit Casino.

Key stats:

Feature	Details
Reels and Paylines	5x3 grid, 30 fixed paylines
RTP	95.67%
Volatility	Medium
Max Win	500x your stake
Bet Range	$0.10 to $500 per spin
Bonus Features	Cash Collect mechanic, Free Spins with sticky Cash Collect symbols, Wilds

This slot game is stacked with cool features, but you need a bit of time to learn about them before you start wagering real money.

Cash collect symbol

The standout feature in Sahara Riches is the cash collect mechanic, which keeps the action engaging. In the base game, you’ll often see gold coins with cash values land on the reels. To collect these prizes, you need to land the cash collect symbol, which appears only on the fifth reel during base gameplay.

Free spins

The free spins bonus is triggered by landing the cash collect symbol along with special numbered symbols (+3, +5, etc.), which determine how many free spins you’ll receive. During the free spins round, the cash collect symbol can appear on all reels and becomes sticky for up to three spins.

Jackpots

There are four fixed jackpots up for grabs:

Jackpot Type	Multiplier
Mini	20x your stake
Minor	50x your stake
Major	200x your stake
Grand	500x your stake

To win a jackpot, you need to land a diamond symbol along with a cash collect symbol. The jackpot you win is randomly assigned.

While Sahara Riches looks and feels great, its math model may leave players wanting for more. The RTP of 95.67% is decent, but not exceptional, and it’s worth noting that some operators may offer lower RTP versions of the game.

The medium volatility means you can expect a mix of smaller, frequent wins, but the 500x max payout is a bit short.

Book of Dead

Anyone who played slot games must be familiar with the Book of Dead game. Launched by Play’n Go, Book of Dead is a perfect title to learn how to play slots. The game centers around Rich Wilde, an Indiana Jones-like adventurer on a quest through ancient Egypt to uncover hidden treasures. With rich graphics and an epic free spins feature, this slot has become a go-to for adventurous players.

It plays on a 5x3 grid with 10 adjustable paylines, so you can easily customize your bets. The high volatility and maximum payout of $500,000 offer plenty of fun. Book of Dead is also fully optimized for mobile.

With an RTP of 96.21%, Book of Dead falls within the industry standard for online slots. The high volatility means wins may not come frequently, but when they do, they can be substantial. I tried it on Bitcasino, and it was awesome, especially because this casino works flawlessly on any device.

Key stats:

Feature	Details
Reels and Paylines	5x3 grid, 10 adjustable paylines
RTP	96.21%
Volatility	High
Max Win	$500,000
Bet Range	Adjustable (varies by casino)
Bonus Features	Free Spins with expanding symbols, Gamble Feature

As for the special features, there are only two, but that’s enough to keep you going. Sometimes, less is more.

Gamble feature

The gamble feature adds a risk-versus-reward dynamic to Book of Dead. After every win, you can hit the gamble button and wager your winnings. Correctly guess the color of the next card to double your payout, or guess the suit to quadruple it. Be warned, though: a wrong guess means you lose it all.

Free spins

The free spins feature is the main highlight of Book of Dead. It triggers when you land 3 or more Book of Dead scatter symbols anywhere on the reels. You’ll be rewarded with 10 free spins, and additional scatter symbols during the round can retrigger more free spins.

Before the feature begins, a random symbol is selected to become an expanding special symbol. This symbol will expand to cover an entire reel if it forms part of a winning combination. Even better, it doesn’t need to be adjacent to create a win, as long as it’s on an active payline.

Wolf Gold

Wolf Gold by Pragmatic Play is a slot that you can find in most crypto casinos. It features a 5-reel, 25-payline setup and medium volatility, so it’s a solid choice for all kinds of players. Add the potential to win three jackpots - Mini, Major, and Mega - and it’s clear why this game has such widespread appeal.

The game runs smoothly across all devices, and its bet range of $0.25 to $125 per spin ensures accessibility for casual players and high rollers alike. The Wolf Wild and scatter symbols enhance the base game, while features like money respins and free spins keep the excitement alive.

Also, there are three jackpots:

Jackpot Type	Multiplier
Mega	1,000x your stake
Major	100x your stake

With an RTP of 96.01%, Wolf Gold sits comfortably within industry standards. Its medium volatility makes it suitable for a variety of play styles.

I played this game on Bitcoin Casino, and I loved how the game works. Everything is fast, and I also enabled the turbo mode, which makes spin really fast.

As for the features, Wolf Gold is as simple as they come with only two features available.

Scatter symbol & free spins

The scatter symbol, represented by a glowing red rock, triggers the free spins feature. Landing three scatters on reels 1, 3, and 5 awards five free spins. During this round, reels 1, 2, and 3 merge into a giant symbol that can significantly boost payouts. The feature can also be retriggered.

Money respin feature

The money respin feature is a highlight of Wolf Gold. Landing six or more money symbols anywhere on the reels triggers this bonus. Regular symbols are replaced with moons, and players receive three respins to collect more moons. Each time a new moon symbol appears, the respins reset to three.

This feature is also the pathway to Wolf Gold Jackpots, with the ultimate goal of filling all 15 reel positions with moon symbols to claim the Mega Jackpot.

The Goonies

The Goonies by Blueprint Gaming brings the nostalgic magic of the 80s cult classic to the reels. This 5-reel, 20-payline slot perfectly captures the adventurous spirit of the movie with cool visuals and original soundtrack clips.

With a 96% RTP, The Goonies is more than okay, as it offers balanced returns. The maximum win of 10,000x your stake is a tempting prize for adventurous players.

I enjoyed this game on Bet Victor Casino, and it’s quite cool to see how this slot works. Everything is easy and the gameplay is quite streamlined.
