Casino Glossary

A structured method for determining how much to wager based on previous outcomes or predetermined patterns. Examples include the Martingale, Fibonacci, and Labouchère systems. No betting system can overcome the house edge, which is a mathematical advantage built into every casino game.

The statistical advantage the casino maintains over players in any game. Expressed as a percentage, it represents the average amount a player can expect to lose relative to their wagers over an extended period. For example, a 2% house edge means the casino expects to keep $2 of every $100 wagered.

The degree of fluctuation in results around the expected mathematical average. High variance games produce larger swings between wins and losses, while low variance games show more consistent results. Understanding variance helps players manage expectations and bankroll requirements.

The practice of setting aside a specific amount of money for gambling and determining bet sizes accordingly. Proper bankroll management involves setting loss limits, bet units as a percentage of total funds, and maintaining discipline to avoid depleting your gambling capital quickly.

The mathematical likelihood of a specific outcome occurring. In casino games, probability determines the odds offered for each bet. Understanding probability is fundamental to analyzing betting systems and making informed decisions about which games offer better mathematical values.

The average amount a player can expect to win or lose per bet over time, calculated by multiplying the probability of each outcome by its payout. Negative expected value indicates the game favors the casino, which is true for all casino games in the long term.

A negative progression strategy where players double their bet after each loss, aiming to recover losses with a single win. While theoretically sound in ideal conditions, the Martingale requires unlimited bankroll and has no betting limit restrictions, which are impractical in real casinos.

A betting system based on the mathematical sequence where each number is the sum of the previous two numbers. Players increase bets following this pattern after losses and decrease after wins. Like other systems, it cannot change the fundamental house edge mathematics.

A standard betting amount established at the beginning of a gaming session, typically calculated as a small percentage of total bankroll. All subsequent bets are measured in multiples of this unit, allowing for proportional betting and bankroll preservation.

A conservative betting approach where players wager the same amount on every bet. Considered the most mathematically sound approach, as it ensures longer gaming sessions and allows players to enjoy entertainment without rapidly depleting their bankroll.
