Casino Games Payout Odds

Unfortunately, calculating the payout odds for casino games is not that simple because each has its payouts and odds. The odds for casino games tell you about the likeliness of a bet winning and how much it will win. This probability can be expressed in fractions or percentages.

  • Decimal:25 (for underdogs) 2.2 (for favourites). These are used at most sports betting sites. With these odds, they represent the amount you will win for every $ you wager.
  • Fractions: UK sports betting sites use this method to calculate the odds. The conversion for these calculations is difficult to understand.
