Rummikub uses a specific rule set for scoring:the winner receives a positive score equal to the sum of all tile values remaining on the losers' racks. The losers receive a negative score equal to the sum of the tiles still on their own racks. The sum of all players' scores in a single round must always equal exactly zero. This application allows you to enter users in number from 2 to 6 and keep score by simply entering the round winner and the total of the tiles left for the other players. It also keeps track of who started the round and who starts the next round. You can sort users on order entered or descending scores. Editing the last round is also a feature.
