1. Rummikub is a tile game where the objective is to be the first player to eliminate all tiles from your rack by placing them in groups or runs on the table. 2. Players take turns drawing and placing tiles on the table in valid sets of at least 3 tiles of the same number or consecutive numbers. 3. The game ends when one player empties their rack and calls "Rummikub", with losing players adding up the points of remaining tiles as negative scores and the winner scoring the sum of losing players' scores.
