About this puzzle

17 of the 36 lamps on this 6×6 board are lit. Exactly one set of lamps switches them all off, and it takes 5 presses.

Where to start

If you chase the lights down row by row, the solution presses one lamp in the top row.

With only a few presses needed, look for lit crosses — a lamp surrounded by lit neighbours is often one press away.

→ Counting moves: bridges, skyscrapers and lights
