Yahtzee is a classic dice game played with 5 dice. Each player's turn consists of rolling the dice up to 3 times in hope of making 1 of 13 categories. Examples of categories are 3 of a kind, 4 of a kind, straight, full house, etc. Each player tries to fill in a score for each category, but this is not always possible. When all players have entered a score or a zero for all 13 categories, the game ends and total scores are compared.The traditional (public domain) game Yacht predates the trademarked game, and has slightly different scoring. - BoardGameGeek
