Before you begin
Does it need an internet connection?
Gameplay, hints, saves and progress backups work offline. Buying and downloading the app uses Google Play. Opening support links uses your browser.
Can I move my progress to another phone?
Yes. Export a progress backup in Settings, move the file yourself, then restore it on the other phone. It includes every room's undo history and best route. Appearance and sound settings stay on each device. Backups are not encrypted.
Can I play without sound or quick reactions?
Yes. Nothing depends on sound or speed. Numbered shapes, text room details, large-text layouts, keyboard controls and both themes support different ways to play.
