Understanding Casino Mathematics
Casino games are governed by mathematics. While the house always has an edge in the long run, understanding probability and expected value helps you make smarter decisions and manage your money effectively.
House Edge
The mathematical advantage the casino has. For example, American Roulette has a 5.26% house edge, meaning you lose $5.26 for every $100 bet on average.
Volatility (Variance)
How much your results swing. High volatility games (like Slots) have big wins and long dry spells. Low volatility games (like Blackjack) are more steady.
Frequently Asked Questions
What is Expected Value (EV) in casino games?
Expected Value (EV) represents the average amount you can expect to win or lose per bet over time. A positive EV means a bet is profitable long-term, while negative EV means the house has an edge.
How does the Mines calculator work?
The Mines calculator computes probabilities and payouts based on the number of mines and gems revealed. It shows you the exact multiplier at each step, the probability of success, and helps you decide the optimal cashout point.
What is the Kelly Criterion?
The Kelly Criterion is a mathematical formula that calculates the optimal bet size based on your edge and bankroll. It maximizes long-term growth while minimizing risk of ruin.
