One of the many advantages of an online casino is it can host many more games than its bricks-and-mortar cousins. When it comes to slot games, that means many hundreds of different titles. In some online casinos, you could try a different slot every day for more than three years and still not play the same one twice.

Yet despite the vast choice, many players return to the same slot games time and again. There’s something about our top five picks that keeps customers spinning those reels.

Have you tried the top five popular slots in 2021? If not, don’t worry, they are all at TwinSpires Casino. If you can’t find them easily (we did say there are hundreds available), simply use the search icon at the top of the casino screen.

Red Hot Tamales

It’s the slot that’s as red-hot as it is simple. Red Hot Tamales has just three reels and a classical look and feel, but it is so atmospheric you can almost taste the chili on the tip of your tongue.

Catchy Mexican music jaunts along as you spin the reels, trying to land a winner on one of 27 paylines. There’s nothing complicated in this IGT game, just match the bars or lucky seven symbols to win. Land a wild symbol to increase your payout chances.

88 Fortunes

From spicy Mexico to the charms of the Orient, the next of our most popular casino games is 88 Fortunes. With Far East musical effects and crashing gongs, you aim to win via the 243 different ways system, rather than regular win lines.

It’s a gorgeous looking slot, and Scientific Games has worked hard to create an authentic atmosphere. Match up the golden symbols and trigger free spins as you attempt to rack up your winnings. Or go for big money by launching the Fu Bat jackpot.

Crazy Money II

A crazy name for a crazy game. Crazy Money II features dollar bills as the symbols on reels seemingly turned by a giant money-printing press. Maybe it will print money for you?

Trigger the bonus features with three or more bonus wheel scatters across the five reels. There are three bonus games to shoot for: Mint bonus, Money Catch bonus, or a bet multiplier bonus. Crazy Money II from Incredible Technologies is fun, and it’s fast.

Star Watch Fire

Explore a galaxy far, far away, and win big with Konami’s Star Watch Fire slot. A 5-reel, three-row slot game, there are 25 paylines as you attempt to match the fiery yellowy-orange symbols.

Make use of Volcano wild symbols, and land three or more burning sun scatter symbols to launch lucrative free spins and even a nudging feature. It’s a fun offering, and there’s a chance to win a jackpot, too.


Cash-O-Matic is one of those rare slot games which you love to play but have no clue what’s going on. Okay, you’ll understand how to play, but the theme is just surreal. It’s part Wild West, part Starburst-jewelled symbols, part tumbling avalanche feature mechanic. And then there is a scatter symbol meter on the left, together with a multiplier meter next to that.

Somehow, it all comes together to make a highly engaging game, all with a high tempo, rag-time style piano accompaniment.
