Winner's Dice by Secret Factory Cut & Restored Magicians take advantage of thatWinner's Dice is a normal looking die that can force ANY NUMBER between 1 to 6. It uses a very special technology which makes our die fully examinable. The spectator can check the die and he can try throwing it to make sure the results are random. But actually, you are in control of the outcome! The forcing result can be changed during the performance, so you can do something like having two different predictions written on two white cards facing down
