Which way do the wheels turn?

Tap the right half of a wheel to turn it clockwise, the left half to turn it counter-clockwise. The wheels are meshed, so every tap also turns the neighbouring wheels by a hidden gear ratio · learning those ratios is half the puzzle.

What happens if I run out of taps?

If any wheel is still out of line when your tap budget hits zero, the round is lost. The budget always leaves room over the shortest solution, so a clean run is always possible once you have read the mechanism.

Is the puzzle the same for everyone?

Yes when handed the same seed. The wheel count, the notch count, the hidden coupling, every wheel's starting offset, and the tap budget are all derived from the round seed.

How does difficulty change it?

Higher difficulty adds wheels (up to four), uses finer notches, and scrambles the start further. Higher labyrinth levels shave the tap budget down so there is less room to experiment.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App. Install once and Circle Puzzle works without an internet connection.
