Thinking in Turns
Three short lessons on the puzzle cube, for anyone who never got past one face: what a turn is and how to undo it, why four turns bring you home, and why the order of moves matters.
For grown-ups, from what CubeSensei teaches children at Spark & Anvil.
Read me the moves
You'll need: a puzzle cube, or the cube page on one device.
- One person reads a short scramble aloud from the cube page; the other turns the cube.
- Swap: the turner now reads the undo, last move first, and the reader turns it home.
- Try R U R′ U′ six times together, counting aloud.
- Stop when it stops being fun. Nobody times anything.
