"If you like heinously difficult AI in an abstract board game scenario, The 7th Guest: Infection is a must have." - Eli Hodapp, TouchArcade.com 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. Features • Rich graphical environment with intuitive and engaging game play • Play head to head with friends • Play against Stauf himself... if you can withstand his maddening taunts • Seven difficulty levels. Few will beat Ol' Uncle Henry when he is at his best. • Original soundtrack by MazeDude • Integrated Game Center The Story Old man Stauf built a house and filled it with his toys. Or so the legend goes. It is said that one of these games could be found by entering the madman's laboratory and peering into his microscope. The germs and microbes there seemed to be imbued with his spirit and intelligence. It is also said that perfectly sane people who attempted to beat him at his own game went completely, absolutely, stark raving mad. Trilobyte has brought the microscope to you, giving you the opportunity to take up the challenge. But you play at your own risk. You have been warned.

Terrible to play ### 1/5 — Too hard to be fun *2018-12-02, version 2.0* Title says it all!! 👎🏼 ### 1/5 — Would be great if it worked *2016-10-24, version 1.0* Great puzzle from one of the greatest games ever created. This app, however, does not open properly and a window pops up that prevents any interaction with the app. ### 3/5 — Love it, but it freezes *2016-09-24, version 1.0* Whenever I hit either of the two buttons at the bottom, the game freezes. I have to unload the game from memory and relaunch it. I'll give it five stars when they fix this. BTW, I'd really like to have multiple board variations, too! Thanks! ### 4/5 — Fun but needs to fix the 'reset' bug *2015-03-21, version 1.0* I can't seem to reset the game. It's very fun though, especially knowing the history behind 7th guest ### 3/5 — Great but has a Bug *2015-01-05, version 1.0* The app does not allow you to reset a game once a game has been completed. Other than that, it's great. This bug appeared after ios8. ### 5/5 — Fun! *2013-12-20, version 1.0* Love it! Missed Stauf and his taunts. Hope T7G3 gets funded and made in 2014!!!! ### 5/5 — Infection *2013-11-03, version 1.0* Great age, never gets old. Can waste a lot of time playing this! ### 5/5 — More please *2013-06-16, version 1.0* Great mind game. Please, please do the same type of app for the honeycomb puzzle from 11th hour. ### 5/5 — Incredible *2013-02-28, version 1.0* Works awesome, wonderful strategy game, overall terrific! ## Frequently asked questions about The 7th Guest ### What is The 7th Guest: Infection?
