Chain Factor is a casual Flash game developed by Griff and released on November 21, 2007. In this game, the player drops numbered discs into a grid, one by one, attempting to clear other discs off. A disc is considered "cleared" when it is in a row or column the size of the number on the disc. For example, if you placed a disc labeled 3 into a row of three discs, the disc of 3 would be cleared.
This game, later on, received a mobile port for iOS devices.
