Step-by-step walkthrough
Read the trick
Treat “Teacher wants a rectangle” as an instruction puzzle rather than a trivia test, and check which visible element can produce the requested result.
Important notes
- Keep your finger on the movable item until it reaches the named target; a tap alone may not register.

- Question order can change after an update, so match the wording and screenshot instead of trusting the number alone.
- Restarting the level restores moved objects and counters if an earlier experiment changed the puzzle state.
