In this entry of the Columns series, it's all about playing with your friends in the new multiplayer feature. You can play up to five people. The game's rules stay the same. Match colored jewels with their respective colors horizontally, vertically, or diagonally. Match two or more to create combos that will allow you to raise the floor on your opponent or receive special power-ups. When there's no more room, it's game over. Plus, there's a single player mode if you want to go solo.
