How to play
- Goal: make all 37 lamps glow at the same time.
- Tap a lamp to flip it and every lamp directly beside it. Lit lamps go dark; dark lamps light up.
- Tapping the same lamp twice cancels that pulse. The dotted violet rim remembers which lamps currently have an odd number of taps.
- Par is the fewest pulses possible. Every daily field has exactly one shortest solution, but any route that lights the whole board wins.
