From what I recall, a roulette table has 60 spaces and I think two of them are green (neither red nor black). Perhaps fair coins would work better. You flip three fair coins, and if the first two are the same, but the third is different, you profit. If all three are the same, you lose, and if the first two are different, you break even. I am not sure what you mean by "You can bet on all three". The rules you lay out only describe what happens from the "joint" outcome, not what happens at each roulette table individually.

Since all three coins are fair, outcomes will be one of the following eight:

So, the probability of winning is , the probability of losing is and the probability of breaking even is . Hence, the game is a fair game. By the law of large numbers, there is 100% chance that if you have infinite funds (or the casino is willing to float you infinite credit), you can achieve any amount of winnings that you want. But, in general, you have even chances of winning or losing in this scenario.

Now, if you want to include the rules for Roulette, as well, and these additional methods of winning are "side bets", that changes the problem drastically.
