What is Key & Door?
Key & Door is a comprehensive, browser-based cognitive exercise: collect keys and reach the exit through one-way, lockable doors. It trains logical planning, constraint reasoning, backtracking, and mirrors the format used in real placement assessments, so the pacing you practise against is the pacing you will face.
A session runs about 5-10 min. Nothing to download or install — it runs in the browser on desktop and mobile, with unlimited practice for Pro members.

Key & Door — frequently asked questions
What makes the doors tricky?
- They are directional. A door you walked through may not let you back, so an order that collects both keys can still strand you away from the exit.
Is there an assessment mode?
- Yes. Practice mode lets you retry a board freely; assessment mode scores your first attempt, matching the real round.
