Dice are thrown onto a surface either from the hand or from a container designed for this (such as a dice cup). The face of the die that is uppermost when it comes to rest provides
Sicherman dice dice is a mathematical exercise in elementary combinatorics, involving a re-labeling of the faces of a pair of six-sided dice to reproduce the same frequency of sums as the standard labeling. The Sicherman dice are crazy dice that are re-labeled with only positive integers. The table below lists all possible totals of dice rolls with standard dice and Sicherman dice. One Sicherman die is coloured for clarity: 1–2–"2"–3–"3"–4, and the other is all black, 1–3–4–5–6–8. The Sicherman dice were discovered by George Sicherman of Buffalo, New York and were originally reported by Martin Gardner in a 1978 article in "Scientific
