The 7th Guest: Infection (iPad) app for $0.99

Trilobyte Games has re-built the wickedly maddening “microscope puzzle” from The 7th Guest. Re-imagined expressly for the iPad, The 7th Guest: Infection is a strategy game for two players or for single play against the mad genius, Henry Stauf. Easy to play, but ever-challenging and difficult to master, this new version of the classic game takes advantage of Apple’s Game Center™, enabling you to match your play against friends and other players worldwide.++
