Yam

Yam is a collection of two variants of the classic dice game Yahtzee. One version allows for one to six players and uses standard rules, the other only allows play for up to four players, but each plays with four columns to put their scores in. Each column behaves differently. The first column is filled in to the player's desire, the second column can only be filled in from top to bottom, the third from bottom to top. The last column can only be used to mark throws for which no dice were re-rolled.
