If the payout for a Do not Pass Odds wager is the same as the amount of the Flat bet, then the Odds bet is bridged. The section of your Odds bet that’s the same as the Flat wager is put right next to the Flat wager. Then, the remainder of the Odds bet is placed on top "bridging" them. For instance, suppose you lay a 5 dollar Do not Pass bet and the hurler throws a point of 8. Understanding the true odds for the eight are six to five (for example., six ways to roll a 7, and five ways to roll an eight), you then place 6 dollars in Odds with the expectation of winning five dollars. In this example, if you win the six dollars Odds bet, you earn 5 dollars, which exactly equals the amount you earn with your 5 dollar Flat wager. Therefore, since your Flat bet and Odds wager win the same amount (5 dollars each), you bridge your six dollars Odds wager by laying a 5 dollar chip literally next to your $5 Flat wager, and then putting the $1 chip so it bridges the two five dollar chips.
If the payoff for a Do not Pass Odds bet does not equal the amount of the Flat bet, then the Odds wager is heeled. This basically means you lay the bottom chip of your Odds bet chip stack right next to your Flat bet. Then, position all remaining Odds wager chips on that first chip but offset and angled on that bottom chip (your Odds wager chip stack is crooked due to the fact that it is angled on the bottom chip).
Perturbed? That’s okay, do not get nervous. The dealer is always willing to help if you don’t remember. After a couple of instances, it all makes sense. It will not take long before you are an expert. If you’re not sure what to do the first time you try it, simply inform the dealer, "I would like to place some Odds but I don’t know if it really should be bridged or heeled." The croupier asks, "How much do you want to lay?" Suppose you indicate, "Fifteen dollars to win ten." The croupier will request that you place your chips on the craps table (dealers aren’t permitted to accept anything, in particular chips, directly from a player), and then he correctly heels or bridges them based on the amt. of your Flat bet. You will quickly get the hang of it. Just don’t be afraid to ask the dealer inquiries. His/Her job is just to deal, but also to be courteous and assist the competitors.
