‘DIY Escape Room’ is a free tool that allows you to create or to enhance an Escape Game built for a real world space. You simply set it up with your own game content & then hand the android device over to your player.
Using clues in the real world combined with those in the app allows players to solve puzzles & be rewarded with access to additional maps, photos, videos & audio.

It was developed with Museums in mind (without access to WIFI) but can be used for public spaces and it's even possible to create a game without extra materials in the real world.
