I'm not saying this to call you naive or anything, but people much more qualified to crunch these numbers have crunched them for years in order to optimize the game to be both fun and profitable. A perfectly fair bet would get ya $18.50 on your $37 bet. Not absolutely horrible, but certainly not an edge in your favor.
You lose 100% of your wager every time you lose your hand. 52.6% of the time.Whenever you win you win 94.59% of what you bet, or to frame it more depressingly, lose 5.41% of your wager every time you win a hand. Even if you have like 35$ on the color bet and 1$ on each 0, you're betting 37$ to win 35$ slightly more than half the time. And of those 20 times, two of your bets would lose at any given moment.
