Welcome to PHP Craps

Die 1	Die 2	Sum	Point

The Rules:

If you roll a 7 or 11 on the first roll, you win. If you roll a 2, 3, or 12 on the first roll, you lose. If you roll anything else (4, 5, 6, 8, 9, 10), this is called your "point". You must keep rolling until your point comes up again. If you roll a 7 while trying to roll your point, you lose. Click the red chip to begin.
