Best free spins bonuses (2025)

Sweet Bonanza

This is a fun, candy-themed slot game that’s a little different from the usual slots you might be used to. Instead of having reels and paylines, it uses a 6x5 grid where winning combinations can happen anywhere on the screen.

To win, you’ll need eight or more of the same symbols to land. The symbols include colorful fruits and candy, like apples, bananas, grapes, and watermelons. Plus, it has cascading reels, so winning symbols disappear, and new ones fall in. This gives you more chances to win with a single spin.

The game is flexible when it comes to how much you can bet, so it works for all kinds of players. You can bet as little as $0.2 or go up to $100, and there’s even an Ante Bet option where you can wager up to $125 per spin.

The game has a medium-high variance, which means you’ll get a mix of small wins and bigger payouts. With an RTP of 96.51%, it’s got a fair return for players, and the max win is huge, up to 21,100 times your stake. Sweet Bonanza also has some cool features, like free spins and multipliers.

Book of Dead

For those who fancy a bit of an ancient Egyptian theme, Book of Dead is a top pick. It has five reels and 10 paylines, and the game has high volatility, meaning you might not win that often. But when you do, the payouts can be pretty big. The symbols are about Egyptian treasures, with the main character, Rich Wilde, leading the way.

The Book of Dead symbol acts as both a wild and a scatter, which is super helpful when you’re spinning. The best part of the game is the free spins feature. If you land three or more symbols, you’ll get free spins, and that’s when things can really heat up.

The free spins include expanding symbols that can lead to huge wins. You can win up to 250,000 coins. The RTP is 96.21%, which is about average for slots, and you can bet anywhere from $0.01 to $50 per spin. Plus, there’s a risk (double) game where you can try to double your winnings if you’re feeling lucky.

Starburst

Starburst is one of those classic slots that almost every player has tried at least once, and for good reason. It’s easy to play, with five reels and 10 paylines that work both ways. That means wins can start from the left or the right, which gives you more chances to hit something.

The symbols are bright and colorful gems, plus the classic BARs and 7s. It looks like a space-themed candy machine, and it’s pretty fun to watch everything light up when you win.

This game is known for being low volatility, so you’ll see smaller wins more often. The best part? The wild Starburst symbol. When it lands, it expands to fill the reel and gives you a free re-spin, which can really add up.

The RTP is usually around 96.09%, which is fair, and you can play with bets from just $0.01 all the way up to $100 per spin. It’s not a game for massive wins; the max payout is 500x your stake, but it’s still a solid choice when you're in the mood for something smooth and steady.

Gonzo's Quest

Gonzo’s Quest is a fan-favorite slot that’s been around for years, and honestly, it still holds up. It’s got a cool storyline where you join Gonzo, a Spanish explorer, as he searches for the lost city of gold, Eldorado.

Right from the start, there's a fun 3D intro that sets the vibe, and Gonzo even hangs around on screen cheering you on as you spin. The game plays on five reels with 20 paylines and uses an “avalanche” feature. This means the symbols fall into place instead of spinning, and winning combos explode to make room for new ones.

The real fun starts when the multipliers kick in, especially during the free spins round, where payouts can get a serious boost. It’s a high-volatility game, so wins might not come often, but when they do, they can be big, up to 3,750x your bet. The RTP is right around the 96% mark, and you can bet from $0.20 to $50 per spin.

The Dog House

The Dog House is one of those slots that looks super cute and silly at first, but don’t let the cartoon dogs fool you. This game packs some serious power behind its bark. It’s got 5 reels, 20 paylines, and a whole lot of energy. The bright, playful graphics make it feel lighthearted, but with high volatility and a max win of 6,750x your stake, it’s no joke when it comes to potential payouts.

The best part? The free spins bonus. That’s where sticky wilds with multipliers can seriously boost your wins, and they stay locked in place for the whole round. In the base game, you’ll also see wilds that come with multipliers.

You can bet from $0.20 up to $100, so whether you’re just messing around or going for big wins, there’s room for both. It’s simple, fun, and way more rewarding than it looks, and that’s the main reason why casinos feature as part of their free spins bonuses.
