What are the most popular casino games?

This top 20 comes from two sources: how often players search for each slot, and how often Casumo players open it. We refresh the list now and then, so a game can drop out when interest fades and a newcomer can climb in. For each slot you'll find the grid, the paylines and the feature worth knowing about before you spin. List updated October 2026.

Casumo's top 20 slots right now

1. Big Bass Bonanza

Reel Kingdom made this one for Pragmatic Play, and it's the slot that launched a whole fishing franchise. It runs on 5 reels, 3 rows and 10 paylines. Fish symbols carry cash values, but they only pay when a fisherman wild lands during the bonus spins round and reels them in. Collect enough fishermen and the round retriggers, with a bigger multiplier on everything he catches.

2. Gates of Olympus

No paylines here. Pragmatic Play's Gates of Olympus pays when eight or more matching symbols land anywhere on its 6x5 grid, and winning symbols tumble away so new ones can drop in. Zeus throws multiplier orbs worth 2x to 500x onto the reels, and during the bonus spins those multipliers keep adding up instead of resetting. Max win is 5,000x your stake.

3. Sweet Bonanza 1000

Sweet Bonanza 1000 keeps the original's pay-anywhere grid: 6 columns, 5 rows, eight or more matching symbols to win, tumbles after every win. In the bonus spins, multiplier bombs can now land at up to 1,000x, and the max win goes up to 25,000x your stake. If you know the original, you already know how to play this one.

4. Gates of Olympus Super Scatter

This version of Gates of Olympus adds a Super Scatter symbol to Pragmatic Play's familiar 6x5 grid. The base rules don't change: eight or more matching symbols anywhere pay, wins tumble, and Zeus drops multiplier orbs onto the reels. The Super Scatter brings an extra way to trigger and boost the bonus, so check the paytable to see what it does.

5. Big Bass Splash

Same 5x3 grid, same 10 paylines, but the sequel changes how the bonus round opens. Before the spins start, random modifiers can add extra fish, extra fishermen or more spins, so two rounds rarely look alike. Top prize is 5,000x your stake, well above the original's. If Big Bass Bonanza clicked with you, this is the obvious next cast.

6. 5 Lions Megaways

5 Lions Megaways is Pragmatic Play's Asian-themed slot with up to 117,649 ways to win and tumbling wins. When the bonus triggers, you choose how to play it: more spins with smaller multipliers, or fewer spins with bigger ones. That choice is the part players like, because it lets you set the pace of the round.

7. Bonanza Megaways

Big Time Gaming's Bonanza is the slot that introduced Megaways, with up to 117,649 ways to win. Wins trigger Reactions: winning symbols explode and new ones drop in. In the bonus spins, the win multiplier goes up with every Reaction and doesn't reset between spins, so a long chain carries into the next spin.

8. Book of Dead

Rich Wilde goes tomb-hunting in Play'n GO's Book of Dead, a 5-reel, 3-row slot with 10 paylines. The book is both wild and scatter. Land three or more and you get 10 bonus spins, with one symbol picked at random to expand over whole reels for the rest of the round. Pick a high-value symbol and the screen fills up fast; max win is 5,000x your stake.

9. Legacy of Dead

Play'n GO's Legacy of Dead plays a lot like Book of Dead: 5 reels, 3 rows, 10 paylines and an Egyptian tomb to explore. Three or more scatters give you bonus spins with a special expanding symbol, and more scatters during the round can add extra expanding symbols. Max win is 5,000x your stake.

10. Razor Shark

Razor Shark is Push Gaming's underwater slot with 5 reels, 4 rows and 20 paylines. Mystery Stacks can appear on the reels and nudge into view to reveal matching symbols, and the Razor Reveal feature can flip them into prizes. In the bonus spins, a multiplier grows with each nudge.

11. Sugar Rush 1000

Sugar Rush 1000 is Pragmatic Play's supercharged remake of Sugar Rush. Clusters of five or more matching symbols pay on a 7x7 grid. Every time a win lands on a spot, it gets marked, and further wins on marked spots carry a multiplier that keeps doubling, up to 1,024x. Max win is 25,000x your stake.

12. Reactoonz

Reactoonz is Play'n GO's cluster slot on a 7x7 grid: five or more matching symbols touching each other make a win, and winning symbols disappear so new ones can fall in. Every win charges the Quantumeter, which can unlock features that shake up the grid, and filling it brings the big Gargantoon symbol onto the reels.

13. Starburst

NetEnt released Starburst back in 2012 and it's still one of the most searched slots around. It's a low-volatility slot: 5 reels, 10 paylines that pay both ways. Whenever a Starburst Wild lands on reels 2, 3 or 4, it expands to cover the whole reel and gives you a respin, and a fresh wild during that respin keeps the streak going, up to three times.

14. Madame Destiny Megaways

Madame Destiny Megaways is Pragmatic Play's fortune-teller slot with up to 200,704 ways to win and tumbling symbols. When the bonus triggers, a wheel of fortune lets you pick your mix of spins and multiplier, or gamble for a better combination.

15. Wolf Gold

Wolf Gold is Pragmatic Play's desert-night slot with 5 reels and 25 paylines. Six or more moon symbols trigger the Money Respin, where only moons stick and each one shows a cash prize or one of three fixed jackpots: Mini, Major or Mega. In the bonus spins, the middle three reels lock together and spin as one giant symbol.

16. Mega Moolah

Mega Moolah is the Games Global (formerly Microgaming) jackpot slot with a safari theme, 5 reels and 25 paylines. The jackpot wheel can trigger at random on any spin, and wherever the arrow stops decides which of the four progressive jackpots you win: Mini, Minor, Major or Mega. There's also a bonus spins round where wins are tripled.

17. Temple Tumble Megaways

Relax Gaming's Temple Tumble Megaways is set in a jungle ruin and uses tumbling wins on a Megaways grid. Stone blocks sit on parts of the reels, and wins next to them break them open to reveal more symbols and more ways to win. Bonus spins start with more ways unlocked.

18. Mystery Joker

Play'n GO's Mystery Joker is a classic fruit slot on a 3x3 grid with a handful of paylines. Joker symbols can reveal prizes, and the Super Mystery Joker feature can be played after certain wins. It's one of the simplest games here, and that's the point.

19. Book of Ra

Novomatic's Book of Ra is one of the original book slots: 5 reels, 9 paylines and an explorer searching for treasure in Egypt. The book acts as wild and scatter. Three or more trigger 10 bonus spins with one randomly picked symbol that expands across whole reels.

20. Fluffy Favourites

Eyecon's Fluffy Favourites has been around for well over a decade, which tells you something about its staying power. It plays across 5 reels and 25 paylines. Three or more scatters trigger 15 bonus spins with every win tripled, and a separate pick feature lets you choose prizes one by one until you hit a collect symbol.
