Game of Craps is a game which is played with a pair of dice. You throw them and what matters is the sum of the two face-up sides ( eg. 2&2=4, 1&3=4) so the range of each throw will be from 2 to 12. If you get a 7 or 11 on the first throw you win and if you get a 2, 3 or 12, you lose. Every other result will be considered as your next point target and that's what you should get to win at the required follow-up throw. During the follow-up throw if you get a 7 you lose and anything else does nothing ( except of course from the point target ).
