In your Craps game, the max bet you can make when taking your Pass Odds is three times the pass line bet. You should fix that so that your players are able to make correct odds bets, or at least pay out Pass Odds in increments less than $1.
For example, if I bet $1 on the pass line, I can bet up to $3 on my Pass Odds. The problem is if I were to have a point of 6 or 8 established i wont get a correct payout, because that payout is made at 6:5 and you wont let me bet more than $3 nor pay players $3.6 on that example $3 pass odds bet.
Get that max odds bet to be in line with a B&M casino. Allow bets up to 5× on a point of 6 or 8 and 4× on a point of 5 or 9. If you do the math those odds allow a correct payout (6:5 and 3:2, respectively).
