Mobile game based on the microscopic puzzle from The 7th Guest. Infection can be played against Henry Stauf, the main antagonist from The 7th Guest, with 7 difficulty levels. As in the original game, Stauf often taunts the players between moves. There is also a Mono Y Mono option where two human players can play together on the same device, and a Demo mode where the AI controls both players.
