No clock. Every puzzle you solve takes you a step up, and the next one is a little harder. The first miss ends the climb.
Rules
- You start at the bottom. The first puzzle is easy, and then every puzzle is a little harder than the last.
- Every puzzle you solve is a step up. The number shows how many steps you have climbed.
- Take the time you need. No clock is running.
- No hints and no solutions while you climb.
- One wrong move and the climb is over. Then you see how the solution went.
Your highest step is kept in your browser, and if you have a profile, it goes there too.
Rather race the clock? Try Puzzle Sprint, and in Puzzle training you get puzzles at your own level.
