Gridcannon is a tactical solitaire card game where the player attempts to eliminate all royal cards (Jack, Queen, King) by strategically placing number cards on a grid. Featuring three different modes and three difficulty settings, Gridcannon provides hours of meditative solitaire card gaming. The original concept for Gridcannon was designed by Tom Francis (designer of Gunpoint and Heat Signature) and has been extended to add further challenge and atmosphere in Gridcannon.

Modes
