A payout that matches the real chance of winning.
It is written as ways to lose to ways to win, and at this payout the house edge (the casino's average cut) is 0. In craps, the Odds bet you add behind the Pass line is paid at true odds. Example. With a point of 4, there are 3 ways to roll a 4 and 6 ways to roll a 7, so the true odds are 2 to 1. Put 10 on Odds and you win 20 if the 4 comes first. Other bets pay less than true odds, and that gap is the house edge.
