An easy way to remember the place bet payoff is by memorizing the particular payoff. If a place bet is wagered at less than $5 the casinos will only pay out 1 to 1 or even money, which is not a good deal.
For example, a wager on the 5 will be paid $7 for a $5 bet. Any amount lower than the above suggested will not be paid maximum odds. In order to get the maximum odds payoff for a place bet the player should bet in units of $5 for all the numbers except the 6 and 8, which should be bet at $6. Any of you more seasoned players, please correct any misstatements. I'm a fairly new craps player, but here are the basics (cut/pasted from info I got from a 'craps 101 site').
