Mine is a Self Contained Portable " CRAPS " Table . This one has seen lots of action as seen by wear.
The dice are in a contained area and are activated by a push rod through device
Game is 25-1/4" X 13-1/4" X 2" with a glass top and brass corner plates
Operator of game would be on one side and players on other ( Most likely a bar )
Dice are activated when push rod is pushed from players side ( Floor that dice sit on vibrate for a few seconds, dice jump around and finally come to rest. )
At this point rod on players side is flush with side and cannot be tampered with.
Operator would pay off winning bets and collect losing bets. New bets would be placed.
Operator pushes rod back to players side for next roll and so on.
If Law enforcement comes in bar game could be simply picked up and set behind bar out of site.
