These look like ordinary dice, except that one number has been removed and 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 always on the opposite face to its double, so they are never visible at the same time. This small change makes a huge difference.
These are fantastic if you want to force any number from one to six.
Example Numbers on the a Dice. 1 ,5, 3, 4, 5, 6 So this would allow you by elimination to force the number 2 etc.
