How to play Words of Hanoi
- Lift the top letter. Tap a tube to pick up its top tile. Only the top tile moves.
- Make some room. Tap another tube that has space. Any letter may sit on any other.
- Read top to bottom. Finish when every tube with letters spells a four-letter word from the list. Spare tubes may stay empty.
Tips for this board
- Start with the word that has the most letters already in order. The top letters right now are N, L, P, O.
- Keep a tube empty as long as you can. This board has 2 spare tubes, and an empty one is where you park a letter you need later.
- Build each word from the bottom up: the last letter goes in first.
