Else City

Each locked room holds a small script with a bug; read it, patch it, run it true, and move to the next.

How to play

You face five rooms, each with a short script in a tiny language and a stated goal. Edit the code so the machine meets its goal, then run it. The console shows your variables and whether the goal is met. Solve all five to escape.

• The mini-language has assignment, if/else and while loops
• Run executes your edited script and reports the final variables
• A reference Hint nudges you; fewer hints and faster solves score higher

Controls

• Desktop: type in the editor, press Run or Ctrl/Cmd+Enter; Tab inserts two spaces
• Phone & tablet: editable on touch, but an external keyboard is recommended for coding

Game modes

• Daily: the same five-room set for everyone today
• Practice: a freshly generated set with the New Set button

Tips & strategy

• Trace the variables by hand first — the console shows you exactly where the run diverges from the goal
• Watch loop conditions and off-by-one errors; many bugs are a wrong comparison or starting value
