The craps table is undeniably the most intimidating, visually complex game on the entire casino floor.

Understanding how to place and utilize this incredible bet is the absolute key to playing craps intelligently and maximizing your winnings.
The Mathematics of Free Odds
For example, if the true odds of winning are 2 to 1, the casino will only pay you 1.5 to 1, keeping the difference as their guaranteed profit.

If you place an Odds bet and win, the casino pays you exactly, perfectly at “true odds,” keeping absolutely zero mathematical edge for themselves.

Because the casino makes zero profit from this wager, they completely refuse to advertise its existence on the physical table layout.

You do not need to say anything to the dealer; placing the chips directly behind your line bet universally signals that you are “Taking the Odds.”
The 3-4-5x Odds System
Because the Odds bet yields zero profit, casinos aggressively limit exactly how much money you are allowed to place behind your Pass Line bet.

A smart craps strategy requires placing the absolute table minimum on the Pass Line, and backing it up with the maximum Free Odds you can afford.

By keeping your Pass Line bet small and aggressively maximizing your Odds bet, you reduce the casino’s overall advantage to nearly zero.
