Casinos attract millions of visitors around the world every year, fascinated by the hope of quick winnings. But the question often arises: is it really a question of skill, or is it simply a matter of luck?
The answer depends on the game you're playing. Some games are dominated by random factors, while others allow players to influence the outcome through their skills.
In this article, we'll explore in detail the different types of casino games, depending on whether they're primarily a matter of luck or skill, while presenting the main strategies used by players to improve their chances.
Games based mainly on luck
Some casino games are almost entirely dependent on chance, meaning that the player's skills have little or no impact on the outcome. Here are a few emblematic examples of these games:
The roulette wheel
Roulette is undoubtedly one of the casino's most emblematic games of chance. The player bets on a number, color or group of numbers, and the ball is thrown onto a spinning wheel. The outcome is entirely random, and no strategy can directly influence where the ball will stop.
Roulette odds
| Bet type | Probability of winning (European roulette) | Potential gain |
| Single number | 1/37 | 35:1 |
| Red or black | 18/37 | 1:1 |
| Odd or even | 18/37 | 1:1 |
| Column | 12/37 | 2:1 |
Slot machines
Slot machines are games based entirely on chance. The principle is simple: the player inserts a sum of money, selects a bet, then spins the reels. The results are determined at random by a pseudo-random number generator (RNG). Although some machines offer a higher payout rate, this does not guarantee immediate winnings.

Slot machine features
| Factor | Details |
| Return rate (RTP) | 85% to 98% |
| Variance | Low, medium or high |
| Player influence | No |
Keno
Keno is a game similar to the lottery, in which players choose numbers in the hope that they will be drawn at random. Luck plays an exclusive role here, as there is no strategy to increase the probability of winning.
Games combining luck and skill
Some casino games allow players to use strategies and skills to improve their chances of winning. However, chance remains an important component.
Blackjack
Blackjack is one of the few casino games where the player's skills can significantly influence the outcome of the game. By using an optimal basic strategy, the player can reduce the house advantage to less than 1 %.
Basic blackjack strategy
| Player's hand | Card visible to the dealer | Recommended action |
| 16 or less | 7 or more | Pull |
| 17 or more | Any of them | Stay |
| Aces and 8s or 9s | Any of them | Double |
Certain techniques, such as card counting, allow experienced players to gain an advantage over the casino. However, this practice is often prohibited by casino rules.
Poker
Unlike most other casino games, poker is a game where skill largely prevails over long-term luck. Players compete against each other rather than against the house, and those who master betting strategies, opponent reading and probability can greatly increase their chances of winning.
Factors influencing poker results
| Factor | Main influence |
| Competence | Very high |
| Random | Moderate (card distribution) |
| Bluff | Essential strategy |
Video poker
Video poker is a hybrid game that combines the chance elements of slot machines with the strategies of poker. By choosing the right cards to hold and those to discard, players can optimize their chances of forming a winning hand.
Skill-based games
Although rare in traditional casinos, some games rely almost exclusively on player skill.
Competitive poker games
In poker tournaments, skill plays a vital role. The best players spend years perfecting their strategies, studying probabilities and analyzing their opponents' behavior.
Card counting blackjack
Although blackjack is often classed as a game combining luck and skill, players who can count cards can gain a statistical advantage over the house. This technique requires excellent memory, sustained concentration and absolute discretion.
Strategy limitations
It's important to note that, even in games involving skill, chance can never be totally eliminated. In poker, for example, a highly skilled player may lose a hand due to an unfavorable distribution of cards. This means that variance plays an important role, and even the best players can experience periods of loss.
What's more, casinos take measures to limit the effectiveness of certain strategies. For example, frequent card shuffling in blackjack makes card counting much more difficult.
A combination of luck and skill
Ultimately, most casino games combine elements of luck and skill to varying degrees. While some, such as roulette and slot machinesWhile some games depend almost exclusively on chance, others, such as poker and blackjack, allow players to develop and use strategies to improve their chances.
However, it's crucial to bear in mind that, even in games involving skill, the house often retains a statistical advantage. Playing responsibly and viewing casino gaming as a form of entertainment rather than a source of income is essential to avoid disillusionment.
Finally, if you'd like to delve deeper into the subject, numerous academic studies and books are available to explore the mathematics of the game, advanced strategies and cognitive biases that influence player behavior.
