Yatzy
Yatzy is a dice game similar to Yacht and Yahtzee. It is related to the Latin American game Generala and the English game of poker dice. Yatzy is most popular in the Scandinavian countries and Finland. Gameplay. Yatzy can be played solitaire or by any number of players. Players take turns rolling five dice. After each roll, the player chooses which dice to keep, and which to reroll. A player may reroll some or all of the dice up to two times on a turn. The player must put a score or zero into a score box each turn . The game ends when all score boxes are used. The player with the highest total score wins the game. Scoring. The following combinations earn points: Upper Section: If a player manages to score at least 63 points (an average of three of each number) in the upper section, they are awarded a bonus of 50 points. Lower Section: "Two Pairs" and "Full House" must have different numbers so that the combination 15566 will score 22 as "Two Pairs", but 15555 will score nothing in that category. Some combinations offer the player a choice as to which category to score them  under. A full house could be scored in the Full House, the Three-Of-A-Kind, Two Pairs, One Pair or the Chance categories. So 22555 would score 19 in Full House or Chance, 15 in Three-Of-A-Kind, 14 in Two Pairs or 10 in One Pair. Differences from Yahtzee. Yahtzee rules and scoring categories are somewhat different from Yatzy: Variations. The two most common variations are "Forced Yatzy" and "Maxi Yatzy": Forced Yatzy. In this variant the players must score in exactly the same sequence as listed above, i.e. "Ones" first, then "Twos", and so on. The  requirement for upper section bonus is reduced to 42 (two of each number). Maxi Yatzy. This variant is played with 6 dice. There are 20 dice combinations. Here the "Yatzy"-combination is removed and the following combinations are added to the lower section: The score required to earn the upper section bonus is increased to 84 points (four of each number). The value of the bonus is also increased to 100 points. If a player does not use all three rolls during a turn (for example, if a Castle or similar combination is achieved on the first or second roll), the  unused roll(s) can be saved and used during future turns.
