Cammy

Cammy is a Yahtzee variant that tries to evoke a "Southern feel" by stating in the rules that it was played on southern plantations and later by New Orleans gamblers. It also has a steamboat scene on the cover. It is different from Yahtzee mainly by the fact that 10 dice are used, and the low score wins.
Players roll 10 dice on the first roll. On the second roll they choose which of the dice to re-roll. Same on the third roll. After 3 rolls the 10 dice are divvied up into two groups of 5 dice. Each player has a sheet of paper with 10 categories. Players choose a category to score with each of the 2 groups. Each category must be finished after the player's fifth turn.
