I too love the dice game, I did learn a different spin on it at a recent training. For me I play the dice game when we do the door prize slip.
First I have everyone roll the dice and put the number rolled on top of door prize slip and circle it.
tell them I will explain later,
when I get done with the slip, I then tell them about the game and ask them if they would like to play or pass, if play hand them the envelope with the number they rolled, if pass thank them and go to next person. IMPORTANT, remind all no looking at envelope until everyone has decided to play or pass.
When everyone has decided this is when you can also Play Make a Deal depending on how bad you need Bookings, offer to pay for like extra credit, or offer a dollar amount off, item off your display, whatever you want,
