What is House Edge?
House edge is the mathematical advantage the casino has over players, expressed as a percentage of the original bet that the casino expects to win on average over many hands.
House Edge = (Casino's Expected Win) / (Player's Total Bet) × 100%
Example: 0.5% House Edge
- • For every $100 wagered
- • Casino expects to win $0.50
- • Player expects to lose $0.50
- • Over 1000 hands: -$5 expected
Example: 2.0% House Edge
- • For every $100 wagered
- • Casino expects to win $2.00
- • Player expects to lose $2.00
- • Over 1000 hands: -$20 expected
