Similar to the game of Yacht but faster, played with only three dice, and with differing scoring categories.  A score sheet is needed to record player's scores.

Each player in turn tries to score the highest possible amount for each of the thirteen categories on the score sheet.  In each turn players throw the three dice and may then throw any or all of them again in an attempt to improve their score for one of the categories.  They do not have to use two throws and may settle on their first.  Players must fill in a score for a category after each turn but once it is used they may not change it. If a player has used a category and throws dice that are only suitable for it, they must enter a score of nought for one of the unused categories left on the score sheet.  In this case try to choose a low scoring entry to fill in.  For example 1s. Categories may be filled in any order.

After each player has had thirteen turns and all the categories on the score sheet have been filled, the scores are totalled, and the player with the highest, wins the game.
