Any casino should be honest with its players, this is the most important thing.
Guy, I am a very gambling person and I like to spend my evening playing bright slots. Now most casinos are honest, as it is much easier to do business this way.
I didn't mean that. For me, the integrity of slots, roulette and other games is important, so that the chance of winning is equal to the chance of losing.
If you are playing at a reputed casino, you have an equal chance of winning or losing. Also you need to realize that most casino are not honest, so first research which casino's are best and then play there.
