The Most Popular Casino Games

First things first: what are the top five most popular casino games? The truth is that it varies, depending on location. In Las Vegas, slots dominate, dwarfing casino table games by revenue with a ratio of more than 3:1. Blackjack and baccarat vie for second place; baccarat revenue is driven by whales with giant pots of money to burn. In Macau, the Chinese obsession with baccarat accounted for 74% of total gaming revenue, making this classic card game the most popular casino game, with slots in second place.

Whatever way you skin it, the top three games at the casino are slots, blackjack, and baccarat. In Sin City, the also-rans are craps and roulette; in Macau, it’s sic bo, roulette, and blackjack. If you find yourself in Atlantic City, sports betting is also a big player. Let’s take a closer look at these casino classics. We’ll take you through the top five most popular online casino games.

Poker is the ultimate blend of strategy, psychology, and risk. The primary difference is that you compete against your fellow players, rather than the house. The other key difference is that poker is a game of skill. The more you play, the better you get.

Variations

• ♣️ Texas Hold’em: The most popular poker game in the world. Each player receives two hole cards and must form a five-card hand using the shared community cards.
• ♣️ Omaha: Similar to Hold’em but with four-hole cards; players must use precisely two.

More Casino Classics

We’ve explored the top five heavyweight players. Here’s a brief look at five more casino games just bubbling under.

Sic Bo

Sic Bo is a traditional Chinese dice game that involves betting on the outcome of three dice. The name translates as ‘dice pair’ (misleading because the game involves three dice). Sic Bo is fast-paced; a mish-mash of craps and roulette. Like roulette, the betting layout offers dozens of wagering options, ranging from simple bets on high or low totals to specific triple-number combinations. To win, you roll three dice and hope your number hits.

Although not common in Western casinos, Sic Bo is hugely popular in Asia and can be found in online casinos. It appeals to players who enjoy quick results and varied betting styles, though many bets carry a high house edge. Simpler bets, such as big/small (total under or over 11), offer the best odds. It’s purely a game of chance, with no skill involved.

Craps

Craps is an exciting, high-energy dice game that always draws a crowd. If there are cheers on the casino floor, you can bet they are coming from the land of craps. Players bet on the outcome of the roll of two dice, with the most popular wagers being the Pass Line and Don’t Pass. The shooter rolls the dice. The action depends on whether a ‘point’ is set.

Though the table can look intimidating, the game is simple as long as you focus on a few core bets. Craps is one of the few games where players actively root for each other, making it one of the most social and lively experiences in the casino.

Keno

Keno is a lottery-style game where players choose numbers, usually 1 to 20 out of 80, and hope their picks match those drawn randomly by the house. The more numbers you match, the higher your payout. It’s one of the simplest games to play and entirely luck-based.

In both casinos and online platforms, Keno offers the chance for large payouts from small bets. It’s not a fast game, and the house edge is high. However,  its ease and similarity to a lottery draw make it appealing to casual players.

Video Poker

Once upon a time, Video Poker was the belle of the ball. When it first appeared in the late 1970s, it was a sensation on The Strip. Video Poker resembles a slot machine but plays like a simplified version of poker. You’re dealt five cards and can choose which to keep or discard. Based on a poker hand ranking chart, the final hand determines your payout.

It’s one of a few casino games where skill matters; choosing the correct cards can drastically affect your chances of winning. Popular variants like Jacks or Better and Deuces Wild offer high payout potential, particularly when employing an optimal strategy.

Top Tips: How to Play Popular Casino Games

Now you know what to expect when you hit the casino. Here’s how to play them.

Slots

• 🎰 Check the RTP (Return to Player) before you play; aim for 95% or higher.
• 🎰 Know the volatility: High volatility means bigger wins less often; low volatility means smaller, more frequent wins.
• 🎰 Use the free play or demo mode to test the game before wagering real money.
• 🎰 Avoid progressive jackpots unless you’re playing at max bet.
• 🎰 Understand bonus features like free spins, multipliers, and wilds to maximize your play.

Blackjack

• 🂡 Learn basic strategies to reduce the house edge. Use a free strategy chart.
• 🂡 Always split Aces and 8s. Never split 10s or 5s.
• 🂡 Know when to double down, especially on 10 or 11 versus a weak dealer card.
• 🂡 Use a consistent bet size unless you’re an advanced player using card counting.
• 🂡 Avoid side bets like ‘Perfect Pairs’ or ‘21+3’. They usually have a high house edge.

Roulette

• ⚙️ If possible, choose European roulette over American (better odds with a single zero).
• ⚙️ Stick to even-money bets (red/black, odd/even) for lower risk and more extended play.
• ⚙️ Remember that betting systems (like Martingale) don’t change the odds.
