Chicago

Chicago, also called Rotation, is a game for any numberof players. Two dice are used. The game is based on the 11 possible combinations of the two dice — 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 — and so consists of 11 rounds.

Objective
The objective is to score each of these combinations in turn. The player with the highest score is the winner.

Play
Each player in turn rolls the dice once in each round. During the first round, he will try to make a total of 2, during the second, a total of 3, and so on up to 12.

Each time he is successful, that number of points is added to his score.

For example, if he is shooting for 5, and throws a total of 5, he gains five points. If he fails to make the desired number, he scores nothing on that throw.
