When referring to casino games online, the popular slot games tend to be a priority for punters. With vibrant themes, thrilling features, and the potential for massive jackpots, slots form the core of any online casino. But beyond slots, online gambling has plenty to offer even for recreational punters and even high rollers. Whether you believe in luck or prefer to do your thing, the following is a list of the 10 most popular casino games online, each with its own kind of thrill.

1. Roulette

Invented in France in the 18th century, roulette spread quickly throughout Europe and America to become one of the most well-known games in any casino. The game is played using a spinning wheel and a small ball. Players wager on where the ball will land—between red and black, certain numbers, or ranges. There are numbered pockets in the wheel with red and black alternating, and one or two green compartments (0 and occasionally 00 depending on variation). The game is simple to play but builds suspense, hence becoming a classic favorite among casino fans.

2. Blackjack

Also known in Spanish as "veintiuna" or twenty-one, Blackjack is a very old card game dating back to 17th-century France. It became world-famous, particularly in Las Vegas during the 1930s. Players at Blackjack wager against the dealer and attempt to get a hand as close as possible to 21 without going over 21. Number cards are face value, face cards are worth 10, and Aces are worth 1 or 11. The depth of strategy involved in Blackjack is what distinguishes it—players will use strategies like basic strategy or card counting to increase their odds. The combination of skill and chance makes Blackjack worldwide extremely popular.

3. Poker

Poker is a psychological, skill-based, and strategic game, with the most popular version being Texas Hold'em. In this game, players aim to build the best five-card hand from a combination of community cards and hidden cards. From home games among friends to high-roller events like the World Series of Poker (WSOP), poker has a devoted fan base. Other versions include Omaha, Seven-Card Stud, and Caribbean Stud. The bluffing and strategic wagering keep gamblers interested, making poker the most demanding and rewarding casino game to play.

4. Craps

Craps is a fast-paced game of dice that has high energy and social atmosphere. Gamblers wager on the outcome of the roll or series of rolls of two dice. The wagers can be made on a specific number, pass/fail outcomes, among others. Even though the variety of betting options may overwhelm beginners, the excitement and adrenaline of the game often attract them. Craps tables are some of the loudest and most communal areas of any casino. 

5. Baccarat

Many people see baccarat as a high-roller game, but its simplicity of rules and minimal house edge make it extremely player-friendly. The stakes are placed on one of three outcomes: banker hand, player hand, or a tie. Both hands are dealt two cards, and the hand closest in value to nine is the winner. As far back as the 15th century in Italy, Baccarat has managed to survive by virtue of being simple, simplicity of rules, and good odds for the players.

6. Slots

The most popular game offered by both land casinos and online casinos are slot machines. Since the creation of the first mechanical slot machine in the late 19th century, they've grown into interactive video slots with rich graphics, bonus games, and progressive jackpots. Players spin the reels hoping to get identical symbols on one or more paylines. Today's online slots have every theme under the sun—from ancient Egypt and space travel to pop culture and mythology. The thrill of winning a jackpot or starting a bonus round draws players in over and over again. With over 500+ slots to play, something new is always waiting.

7. Pai Gow Poker

Pai Gow Poker is a strange mix of the ancient Chinese game Pai Gow and American poker. All players receive seven cards and must form two poker hands: a five-card "high" hand and a two-card "low" hand. Both of these have to beat the dealer's corresponding hand in order to win. Pai Gow offers a less frantic, more game-like experience that rewards strategy and careful thought. It's particularly appealing to those players that desire a more relaxed, but mentally challenging casino experience.

8. Sic Bo

Sic Bo, or Chinese for "pair of dice," is a very ancient game using three dice. Bets are made on any number of potential results, including numbers, combinations, or ranges. It's primarily played in Asian casinos, especially in Macau. The game offers many betting choices and payout structures, making it an exciting game among variety lovers and risk-takers.

9. Keno

Keno is an ancient Chinese lottery-style game where a player selects a number of numbers (usually 1 through 80), and the house randomly draws 20 numbers. The greater the number of matches, the larger the prize. The game is all chance, but its simplicity and potential for massive payouts have Keno as a favorite among gamers who prefer no-frills play.

10. Video Poker

Video Poker is both the ease of slot machines and poker's skill-based play. It was first launched in the 1970s but reached tremendous popularity in the 1980s. Players are given five cards and have the option to hold or discard whichever they wish. The objective is to create the best possible poker hand, i.e., a Flush, Full House, or Royal Flush. Video Poker also features multiplier options and progressive jackpots, offering a further element of thrill.
