Types of free spins available

Not all free spins are the same. Some come with strings attached, and others are completely risk-free. Also, since this bonus offer is quite tempting for slot players, free spins are often combined with other top bonuses, like welcome bonuses. Here are the main types you’ll come across:

payout-speed

No deposit free spins

No deposit free spins are exactly what you think they are: spins you get without having to deposit any of your own money. All you usually need to do is sign up at a casino, and the platform will give you a set number of spins to try out a popular slot (like Starburst or Book of Dead).

Just keep in mind that these spins often come with high wagering requirements. So, you will have to play through your winnings to cash them out. Also, consider that there is usually a limit on how much you can cash out from these. Still, for a freebie, it’s a solid deal.

hot

Wager-free free spins

This type is the sweetest — these are spins that come with no strings attached. And, it doesn’t matter if you get them from a welcome offer, a standalone promo, or even a surprise email from the casino; the best part is that whatever you win is yours to keep right away.

There’s no need to play through the winnings multiple times before you can cash out. If you win $10 from wager-free spins, you can withdraw that $10 immediately.

support

Social media or promo free spins

Social media or promo free spins are bonuses that casinos give out through platforms like Telegram, X, or Instagram. You’ll often find promo codes in their posts or stories, and you can use these codes to claim free spins.

Sometimes these spins are free; other times, you’ll need to make a small deposit. In most cases, the spins come with low wagering requirements. Also, note that these offers are usually smaller compared to other types, so they vary from 20 to 30 free spins.

bonuses

Welcome bonus free spins

Welcome bonus free spins are spins you get as part of a casino’s sign-up offer, usually when you make your first deposit. For example, a casino might give you 100 free spins on Sweet Bonanza when you deposit $20 or more.

These spins are often bundled with a match bonus (like 100% up to $1,000), so you get both bonus cash and spins to get started. The free spins usually have different wagering requirements, lower than the match deposit.

wallet

Daily/weekly free spins

Daily or weekly free spins are bonuses that casinos give you based on your activity or as part of ongoing promotions. The more you play, the more likely you get these offers.

Some casinos also stretch out free spin deals over several days, like giving you 100 spins total, but unlocking 20 spins a day for five days. It keeps players coming back, and it’s a fun way to spread out the bonus instead of using it all at once.

free-spins

In-game free spins (triggered spins)

In-game free spins, also known as triggered spins, aren’t casino bonuses in the usual sense. They’re actually features built into the slot games themselves. I listed them here because many players confuse them with bonus offers.

These spins are triggered when you land three or more special symbols (like Scatters) while playing a slot. When that happens, the game gives you a set number of free rounds, often with added features like multipliers or sticky wilds. You don’t need a promo code or deposit to get them, they’re all about luck while spinning.

no-wagering

Standalone free spins

Standalone free spins are given out as a bonus all by themselves, not bundled with deposit matches, cashbacks, or other rewards. These offers are usually simple and straight to the point, like “50 free spins on Amusnet slot games” just for depositing $20 or more.

trophy

Loyalty/reward free spins

Loyalty or reward-free spins are part of the casino VIP programs, where the more you play, the more rewards you unlock. These programs often have different levels, and as you climb higher, free spins are handed out as a perk.

For example, if there are 10 levels, you might get 100 free spins at levels five through 10. Also, there are more VIP casino bonuses, not just free spins. These are usually cashback, reload offers, and cash rewards.

Are free spins rewards different when using crypto versus fiat?

In most cases, there is no difference between free spins rewards when using crypto or fiat currency. The key factor is how you make your deposit. Fiat deposits work through traditional payment methods like credit cards or bank transfers, while crypto deposits are made using digital currencies like Bitcoin or Ethereum.

Once the casino receives your deposit, it will issue your free spins, regardless of whether you used fiat or crypto.

However, some casinos offer special crypto-only promotions, where you can earn free spins as part of a bonus for using cryptocurrency. These offers are typically designed to encourage players to use crypto, as casinos often prefer the lower fees and faster transactions that come with digital currencies.

How do free spins bonuses work?

Free spins bonuses are exactly what they sound like: spins you get to play on slot machines without using casino balance. You’re not paying for the spin, but if you hit a win, the payout is yours. That’s the magic of it.

Now, here’s something to keep in mind: these spins usually only work on specific slot games. Some casinos will tie their free spins to popular titles like Big Bass Bonanza or Starburst. So don’t expect to use them on any game in the lobby.

Free spins can come as a standalone offer or as part of a bigger welcome package. Sometimes, you’ll get them just for signing up or verifying your email, like on BitStarz Casino.

Other times, they’re bundled with deposit bonuses or loyalty rewards. One good example is a welcome bonus found on 7Bit Casino: 325% up to 5.25 BTC plus 250 free spins.

Free spins also often drop on specific days of the week, like Wednesdays at Golden Crown Casino.

Either way, it’s free play, and that’s always a win in my book.

Not all free spin bonuses are the same. Some come with wagering requirements, usually around 30x. This means you’ll need to play through your winnings a few times before you can cash out.

Others might have a cap on how much you can win, depending on the bonus offer, the number varies from $100 to $1,000. So, before you get in, always check the terms. It's the not-so-fun part, but it saves headaches later.

Best free spins bonuses at crypto casinos

I’ve tested multiple free spins casino sites that accept crypto, and not all are worth your time. A few really stood out, as they’ve got proper free spins bonuses, not just part of a welcome package buried under fine print. This brings us to my recommendations:

Best free spins slots available

When I tested free spins casinos, I noticed that in most cases, these bonuses were tied to specific slot games. Here are some of the most popular slots I came across that offer top free spin bonuses.

Sweet Bonanza

Sweet Bonanza is a candy-themed crypto slot that uses a 6×5 grid instead of traditional reels and paylines, where wins occur by landing 8 or more matching symbols anywhere on the screen. With cascading reels, winning symbols vanish and new ones drop in, increasing your chances on a single spin. Bets range from $0.20 to $100 (or $125 with Ante Bet), making it accessible to all players. The game features medium-high variance, a 96.51% RTP, and a massive max win of up to 21,100x your stake, plus exciting extras like free spins and multipliers.

Book of Dead

Book of Dead is a high-volatility, ancient Egyptian-themed crypto slot with 5 reels and 10 paylines, offering big win potential despite less frequent payouts. The Book of Dead symbol acts as both wild and scatter, triggering a free spins feature with expanding symbols that can lead to wins of up to 250,000 coins. With a 96.21% RTP, bet limits from $0.01 to $50, and a risk game to double your winnings, it’s a popular pick for players chasing big rewards.

Starburst

Starburst is a low-volatility, space-themed crypto slot with 5 reels and 10 paylines that pay both ways, offering frequent small wins. Featuring colorful gem symbols, classic BARs and 7s, and a standout wild Starburst symbol that expands and triggers re-spins, the game delivers fast-paced, easy-to-follow action. With an RTP of 96.09%, bets ranging from $0.01 to $100, and a max win of 500x your stake, it’s a great choice for players who prefer steady gameplay over high-risk spins.

Gonzo’s Quest

Gonzo’s Quest is a high-volatility crypto slot with 5 reels and 20 paylines, featuring an avalanche mechanic where winning symbols explode and make way for new ones. Set on a quest for Eldorado, the game includes engaging 3D visuals, increasing multipliers, and a free spins round that can boost payouts up to 3,750x your bet. With an RTP around 96% and bet options from $0.20 to $50, it’s a long-time favorite for players chasing big, adventurous wins.
