Indigo 7

Indigo 7 is a color-based single-player and multiplayer game. As you follow the plot through comic-style cinematics, you’ll face different battles and unlock a lot of single-player and local PVP modes that tell the rest of the story. The match rules vary in each mode, but the challenge always stays the same: choose a number of colors to use and make the board yours before your opponent does!
