Primitive game

A very-very simple Dice Game: two persons("You" and "CPU") are dropping dices. If someone scores 17 during dropping dices, he wins. Any doubts are interpreted to a humansside. (im too lasy to add draw here) And one more. Rules say- "if someone Drops 3 same dices at the beginning, he wins." this is not realized in game, too. (but the probability of this is just about 1.4%)
