Twice Dice are also known as”elimination dice” or “one-way tops.” One number has been replaced by another. For example the Double Four has an extra 4 instead of a 3, and the Double Five has an extra 5 instead of a 2. 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 can use these dice to force an outcome. They are also of interest to teachers and students of statistics, and game players.
Here’s an example of how powerful these dice can be when used in a game. Let’s say you are using the Double Six and your opponent is using a Double One. Out of 36 throws, you can expect the Double Six to win 26 times, draw 4 times, and lose only 6 times.
I designed the optional leather case myself. I cut three straps from good quality leather, interweave them, then lock them together with an eyelet. A brass press-stud and stainless steel split ring complete this stylish and practical travel case.
