A high percentage of online casinos do give players a free play casino bonus so that they may try out the casino games without any money risk. This enables the player to enjoy the games the casino has to offers without enduring the risk of losing. The casinos feel that if you enjoy their casino you will continue to play so for them it is a win situation, as a percentage of people will continue to play. The odds on free play casino bonuses are the same as if you were to deposit; the main disadvantage is you are limited to what you may withdraw if you happen to hit a jackpot. Some feel it is not worth the risk and would rather not be liable to meet certain wagering requirements, so they opt out on the free play bonus and elect to play with own cash. This is not a bad idea as they are free to withdraw winnings at any time. A free play casino bonus is just to give the player a taste of the casino games, but not a get rich quick scheme.
