Blackjack. You only lose about .5%. So for every thousand that is bet, the house keeps $5.
Craps, betting pass line and backing up your wager with odds is also a sane bet.
Odds behind the pass line, (and come bet) or laying the odds on the don't pass, (or don't come) is the only wager in gambling that offer true odds. Providing the casino pays 2/1 on 4 and 10, 3/2 on 5 and 9, 6/5 on 6 and 8 behind the line. Not all do anymore just like not all casinos pay 3/2 on a blackjack.
