In an industry where emotions are subject to mathematics and chance is part of the strategy, the question often arises: what games are available in online casinos, and where to start. A common mistake is to choose based on “what looks better.” Practice shows that beginners who focus on visuals lose their balance right from the start. The right path is through understanding mechanics, volatility, return rates, and risk types.
What games are available in online casinos: main assortment
Algorithms do not create chaos. Each genre in a casino is not just entertainment but a specific style with predictable scenarios and parameters. The list is extensive, but most platforms boil down their offerings to eight main directions:

- Slots. The foundation of most platforms. Interface simplicity combines with high volatility. Return to player (RTP) ranges from 91% to 98%. Classics include Book of Dead (Play’n GO), while new releases include Gates of Olympus (Pragmatic Play). They attract with fast dynamics, frequent bonuses, and the chance to win a jackpot.
- Poker. Requires strategy. Players compete against each other, not against a random number generator (RNG). Popular variants are Texas Hold’em and Omaha.
- Blackjack. Mathematics + intuition. One of the few formats where the house edge can be reduced to 0.5% with optimal strategy.
- Roulette. A casino symbol since the 17th century. The European version (single zero) shows a return of 97.3%. The American version has a lower return due to the double zero.
- Baccarat. A favorite format of high rollers. Simple rules, high speed. Dominated by three bets: on the player, banker, or tie.
- Craps. A dice game with a history from Las Vegas. High complexity is offset by better odds (house edge ~1.4%).
- Keno and Bingo. Luck-based formats. Offer high winnings with minimal participation.
- Live dealer games. Recreate the atmosphere of offline casinos through streaming. Servers process actions in real-time, while providers (e.g., Evolution) ensure stable broadcasts.
Each category is not just entertainment but a way to interact with mathematics, gambling, and probability.
Slots: beauty, simplicity, results
The main interest for beginners lies in slots. The reason is the visual appeal, instant bets, and automatic play. Popular online casino games in this category create entire universes: from myths to science fiction. Graphics, sound, bonus rounds—everything is adapted to maintain attention.
Critical parameters:
- Return to Player (RTP): 95–98%—an optimal range for beginners.
- Volatility: low—frequent but small wins; high—rare but large wins.
- Maximum Jackpot: up to several million dollars in progressive slots (e.g., Mega Moolah—over $20 million at its peak).
When choosing, it is important to consider the provider. Games from NetEnt, Play’n GO, and Pragmatic Play demonstrate stable performance and predictable RNG. The risk in slots is high but controllable with betting limits.
Card Games: control, strategy, advantage
In this category, online casinos offer card games—poker, blackjack, and baccarat. The difference lies in the presence of basic logic and the ability to calculate combinations.
Poker requires strategic thinking. The advantage depends on the ability to count cards, consider opponents’ behavior, and assess probabilities.
Blackjack allows reducing the casino’s advantage with the right strategy. A simple example: with a six-card deck and basic counting system, the advantage drops below 1%.
Baccarat is a format with minimal rules and high betting speed. It is often used in VIP rooms. The RTP for banker bets is 98.94%.
Roulette and Craps: physics and luck
Roulette mechanics are visually simple but require careful consideration. The European version (with one zero) reduces the casino’s mathematical advantage.
Craps is a more complex variant with a betting table and two dice. Despite external chaos, the game offers players a range of bets with minimal casino advantage (Pass Line—1.41%).
Both formats are particularly suitable for users preferring moderate risk and a fast pace.
Lottery Formats: quick and simple
Formats like bingo and keno occupy a niche among those seeking minimal involvement and an element of luck. Casino games in this category practically require no knowledge.
Bingo—balls are drawn by a generator, and the user marks combinations. Often offers progressive jackpots.
Keno—pick up to 20 numbers from 80. Guessing numbers multiplies the win. Some versions include multipliers, increasing excitement and potential profit.
Dealer Games: bridging online and offline
The popularity of live casinos has grown by 43% in the last three years. The reason is live interaction. Providers like Evolution and Ezugi use studios with professional dealers, HD cameras, and secure servers. The rules are identical to offline games, enhancing user trust.
Games available in online casinos in the live segment include roulette, blackjack, baccarat, and game shows. Connection stability and interface are critical here—a delay of more than 2 seconds worsens perception and reduces engagement.
How to choose a game for a beginner: a simple strategy
A beginner faces an abundance of options. To avoid losing money in the first few minutes, it is worth considering three basic parameters: engagement level, mathematical advantage, and volatility.
A universal selection scheme:

- Low risk + simplicity—slots with low volatility, keno, bingo.
- Medium risk + control—blackjack, baccarat, roulette (European).
- High risk + strategy—poker, craps, slots with progressive jackpots.
This selection structure allows balancing excitement, entertainment, and chances of winning.
What games are available in online casinos: conclusions
The question of what games are available in online casinos goes beyond a simple list. It is a choice between control and chance, speed and strategy. A novice should approach the first step as an investment in experience. Game mechanics, returns, providers, bonuses—each detail affects the outcome. A successful start sets the direction where entertainment follows strategy, and risk follows calculation.
