I am surprised the people running the table didn’t call this out. When I first played craps it was at a busy table in Vegas. I was passed the dice to roll and I didn’t throw them hard enough to hit the back wall. The people running the table said the roll didn’t count and asked that I make sure they bounce off the back wall.
