If the pay out for a Don’t Pass Odds bet equals the amt. of the Flat wager, then the Odds bet is bridged. The part of your Odds wager that’s the same as the Flat wager is laid literally beside to the Flat bet. Then, the remainder of the Odds bet is laid on top "bridging" them. As an example, suppose you lay a 5 dollar Don’t Pass bet and the shooter tosses a point of eight. Understanding the true odds for the eight are six to five (for example., 6 ways to roll a 7, and 5 ways to roll an 8), you then place 6 dollars in Odds with the expectation of acquiring five dollars. In this example, if you win the 6 dollars Odds wager, you win 5 dollars, which clearly equals the amt. you earn with your five dollar Flat bet. Therefore, since your Flat wager and Odds bet win the same amt. (5 dollars each), you bridge your six dollars Odds bet by putting a $5 chip literally next to your $5 Flat bet, and then placing the $1 chip so it bridges the two five dollar chips.
If the payoff for a Do not Pass Odds wager doesn’t equal the amt. of the Flat bet, then the Odds bet is heeled. This basically means you position the bottom chip of your Odds bet chip stack exactly beside to your Flat bet. Then, position all remaining Odds wager chips over and above that single chip but to the side and leaning on that bottom chip (your Odds bet chip stack is crooked due to the fact that it’s leaning on the first chip).
Befuddled? That’s fine, do not get nervous. The croupier is always ready to help if you don’t remember. After a couple of times, it all makes perfect sense. It won’t take too much time before you’re a pro. If you are not sure what to do the first time you try it, basically inform the croupier, "I want to lay some Odds but I don’t know if it needs to be bridged or heeled." The dealer asks, "How much do you wish to put?" Let’s assume you indicate, "$15 to win ten." The croupier will request that you drop your chips on the craps table (croupiers are not allowed to take anything, notably chips, right from a competitor), and then the croupier properly heels or bridges them based on the amt. of your Flat wager. You will quickly get the feel of it. Just don’t be afraid to ask the croupier inquiries. His or Her job is not only to deal, but also to be accommodating and assist the gamblers.
