Balut is a dice game similar to Yahtzee. It was invented by an American stationed in the Philippines at the end of World War 2, and is a popular social game with the Dutch, with organized play and competitions. The name of the game is derived from the partially-fertilized eggs popular in the Philippines and other parts of SE Asia. The game involves rolling five dice up to 3 times to make various combinations, which are noted on a scorecard. A Balut is a five-of-a-kind of any denomination, Players who obtain a Balut announce it to the other players by calling out "Balut!"—similar to calling out "bingo!", and note it on a special scorecard. Players try to guess before gameplay how many Baluts will be made during the game; correctly guessing the total number can earn a prize.
