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 One number has been replaced by another.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 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!
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 to roll a higher number than your opponent 26 times, draw 4 times, and lose only 6 times.
Size : 16mm (5/8inch)
Shape : rounded edges and corners
Colour : white with black spots.
Materials : injection-moulded plastic.
Other features : The blank dice are made in England from injection-moulded plastic. I use a precision jig system to machine the pip indents into exact position then colour them with a mica infused acrylic paint which is extremely hard-wearing.
