The brain teasing rummy-style puzzle game. It is based on rules of the rummy-style games like Rummy or Rummikub.
There are 106 tiles in the game including 2 jokers. There are 4 different color tiles, black, red, yellow, and green numbering 1 through 13. The objective of the game is to be the first to eliminate all the tiles from your rack by forming them into sets of runs and groups, and then melding them onto the table. All runs must consist of at least 3 tiles of the same color and consecutive rank. Groups must consist of 3 or 4 tiles of different colors. A Joker may be substituted for any tile when you make a meld. Once you have placed your initial 30 points down, you are free to play on the table and manipulate and rearrange melds. If you cannot add onto the other runs or groups of yours or opponents, you must pick a tile from the table. Then you must wait until your next turn to play.
