Here is another automatic dice roller from the 1960s. The Cragstan Crapshooter automatically shakes and rolls the dice. It moves the dice cup with its right hand and 3 dollars with the other. You can also see the rubber face twitching as a new set of dice is rolled.
The Cragstan Crapshooter measures 6″ W x 6″ D x 10″ H. It is pretty rare but you can find both working and non-working versions on eBay.
