Marble Matrix

Forty-eight marbles, each in one of six colors, are placed onto a 7X7 grid, with the center grid space left empty. Players take turns sliding marbles across the grid so that two or more matching marbles line up. The players collect those matching marbles. Play continues until a player cannot create any matches. Each player then scores one point for each set of three matching marbles that she has collected. The player with the most points wins.
