Puzzle workshop.

Ungraded puzzle references to try. Explore the idea, then tell us where you had to stop and think.

These references have no difficulty rating yet. Try one before opening its design notes. Runs stay in this tab; your campaign progress is separate.

REFERENCE
ONE IDEA. ROOM TO EXPLORE.

After playing

Try without design notes first. These observations stay in this tab and are included only when you choose Send feedback.

What changed your plan?

After trying a reference, tell us which move you had to predict, where a wrong choice became clear, and whether the walking outlasted the idea. Include the gym, your input device and whether you read the notes.
