About this puzzle
23 of the 49 lamps on this 7×7 board are lit. Exactly one set of lamps switches them all off, and it takes 16 presses.
Where to start
If you chase the lights down row by row, the solution presses 3 lamps in the top row.
On 7×7, chase, read the bottom row, press the top-row lamps it names, and chase again.
