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

This secret wager is universally known among veteran players as the "Free Odds" bet, or simply "Taking the Odds."
The Zero Percent House Edge Explained
To understand why the Odds bet is so incredibly powerful, you must first understand how casinos normally make their massive profits.

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.

For example, if you bet $10 on the Pass Line, and the Point becomes an 8, you can place a maximum of $50 in Free Odds behind it.

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