The Scarborough Joke Shop Twice Dice Set Accessories

These dice are known as Twice Dice
(sometimes called “Elimination Dice”, “Forcing Dice” or “One-way Tops”).

On each die, one number has been replaced by another. For example the Double-Six has an extra 6 instead of a 1, and the Double-Five has an extra 5 instead of a 2, and so on…
The extra number is on the opposite face to its double, so they are never visible at the same time.
Only a close examination will give the game away.
Magicians use these dice to force a predetermined outcome. Role-playing gamesters use them to fine-tune the odds on certain eventualities. They are also of interest to teachers and students of statistics … not to mention unscrupulous tricksters who want to win dice games!
