Primrose‘s gameplay is deceptively simple: You’re given random pairs of colored tiles that you must place on a 7×7 grid. When you surround a group of one color with another color, the surrounded group clears, scoring points. The surrounding tiles flip to the color of the tiles that were cleared. When tiles flip color, chain reactions are possible. Larger groups and longer chain reactions are awarded more points. As the game progresses, more colors are added to the pool, making the grid more and more constrained. Ported to Pandora by mcobit.
