In Matchpoint, the first title in The Game Master's "Smart & Fun" game line, players take turns placing one of two tiles in hand onto the playing area, turning the tile this way and that to determine the best way to earn the most points.
More specifically, each tile is comprised of four colored quadrants, with each quadrant having a number of pips: purple has five pips, blue has four, and so on. One tile is placed face-up on the table at the start of the game. On a turn, you place a tile next to tiles already in play, then score the sum of all pips in the colored areas that you add to with the placed tile. (In the advanced version of the game, you multiply the sum of all pips by the number of colors that you matched on that turn.) You then draw a replacement tile, and the next player takes her turn. whoever has the most points when the tiles run out wins!
The rules also include a solo variant.
