We are a small company that creates its own escape games with a detective story since 2015. The first game made from LostExit, was the House of Grief (2015-2020 in Prague-Kobylisy). Our advantages are originality, linguistic independence of games and reasonable suspence with a background of real environment. We currently run the non-linear games Special School (since 2018) and Cinema Úsvit / Dawn (will be opened since mid-2020) with a minimum of padlocks. Visitors have an above-standard time limit of 80 minutes for the game, the pairs have a customized variant of the game.
