The player's disadvantage in some online casinos is a result of the casino not paying winning wagers according to the game's "true odds", which are the payouts that would be expected considering the odds of a wager either winning or losing. For example, if a game is played by wagering on the number that would result from the roll of one die, true odds would be 6 times the amount wagered since there is a 1 in 6 chance of any single number appearing. However, the casino may only pay 5 times the amount wagered for a winning wager.

The casinos listed in our sites are offering more than average payouts, and all are bring reviewed and verified by major accounting firms to approve it, some even include the eCogra eGAP "Play it safe" Certificate.
