Before starting, determine how many rounds will be in a game. One or two is suggested for shorter games--five or ten for longer ones.
The object of Decimate 'Em is for players to eliminate as many numbers as possible from the block during their turns. This is done as follows:
The first player rolls the dice and removes one or more pegs marking the numbers whose total exactly equals the total on the dice. For example, if a 7 is rolled, the player may remove peg #7, or pegs #6 and #1, or pegs #4, #2 and #1.
He continues to roll as long as he can eliminate numbers whose total exactly equals the dice roll. He must remove the total amount on the dice or none. When the latter happens, he loses his turn. His score for the round is the sum of the numbers still marked by pegs. The next player fills the block with pegs and begins his turn.
When the last player has completed the final round, the individual scores for each round are added. The lowest score wins.
