Blackjack requires some skill. Although I have seen others play with none what so ever. Roulette is luck. One day IM walking though Paris and see people crowded around a roulette table. One color had come up many times in a row. Now I know the next spin is independent of the last,but I try to get a bet in on the due color and can't get near the table the next spin. Same color comes in. I make it for the following spin and place 100 down and the opposite color came in. I picked up my 200 and kept walking. Barry
