The Game of Tao

Eighty square tiles are tossed into a bag. Each tile displays one of three colors, one of three shapes, and one of three numbers. On their turn, a player draws tiles to refill their hand to four tiles and then plays up to three of those tiles in a straight line onto a grid of previously played tiles so that the shapes, numbers, and colors of each line created or extended are either all the same or all different. Score a point for each tile in a line that is created or extended. Score bonuses for playing three tiles and for creating lines of three tiles. Play until the bag empties, and one player plays all their tiles. Then, subtract the number of every other player's leftover tiles from their score and add the sum of those tile to the score of the player who went out. Most points wins. —description from the publisher
