Decisions relate to inputs from dataflow (D7, D711, D2312, EQ) and outside world (Rb and Reset).

Outputs to dataflow (Sp and Roll) and outside world (Win and Lose).

States (reset, roll dice, roll done) and.

Play continues until the player wins or loses.

Otherwise, the player must roll again.

Otherwise, the sum is either 4, 5, 6, 8, 9, or 10 and is saved as the point and the player must roll again.

if it is 2, 3, or 12, the player loses.

After rolling the dice (two six-sided die), the sum is tested.Review rules (view from state information).Controller Craps Dice Game Switching and Logic Lab Standard Laboratory Exercises
