During our 3 year experience as avid roulette games players, we've played at literally hundreds of play pokers. We've seen casinos that will cheat you, will not pay you what they owe you, will not answer your emails... and then there are the good ones.
The chant has been that poker is a safer option. Credit card fraud is deemed to be much lower, it is easier to track winnings and there is no risk in carrying large amounts of cash around late at night. You are in the comfort and security of your own home.
Playing and practicing at home will teach you the proper strategy and help build your confidence. Once you have your mistakes down to a minimum you will be ready to play in the free casino.
