Played acey deuecy in the Navy. We once had an unofficial squadron tournament where anyone that wanted to compete would put in $5.00. I'm not sure now how many participated I only remember winning the money. That was before getting married. I'm pretty sure my buddies & me had a great time in San Juan.
The way the dice were thrown in this case dropped was thru a plastic box tower. It had three shelves that the dice had to trickle back & forth & down on. There was no way for anyone to manipulate the dice. Getting good combination of numbers was pure luck.
