In BC Casinos, most chance-based games have their payout odds listed on the tables or machines. House advantage for these games is generally between 1% and 10%, with greater advantages being enjoyed on higher payout outcomes such as bonuses, baccarat ties, etc.
For poker and other skill-based games, casinos simply rake the pot to earn their commission.
Slot machine games come in many varieties, each with different jackpots and different outcome possibilities. The probability of winning the top prize at maximum coin play in a slot machine can range from 1 in 4,096 to 1 in 33,554,000. House advantage is built-into most games, which is why the house is favoured to win.
