Invisible City‘s latest free game of the month is a fast-paced, two-player paper and pencil game which works like a cross between Minesweeper and Battleship. Each player marks a treasure chest and several bombs on a sheet representing a cube. Players then take turns moving on a common board, trying to find each other’s treasure chests without being blown up. Numerous variants are provided for those of you who don’t think this sounds interesting enough, though we’ll have to wait until the year-end review to learn more about the rules for Explosive Mole Launchers.
