Roulette: Odds & House Edge
Roulette's payouts are set so that every bet on a given wheel carries the same house edge — the only real decision is single-zero (European) versus double-zero (American).
The green zero(s) are the entire edge: they aren't covered by any outside bet, so red/black, odd/even, dozens, and straight numbers all lose to them.
