🏮 Lanterns

Light every lantern. Each tap switches a lantern and its neighbours.

Tap any lantern to begin. Watch which neighbours change.

How to play

Light every lantern on the 5×5 grid. Tapping a lantern switches it, and the lanterns directly above, below, left and right of it, between lit and dark.

Order doesn’t matter, and tapping the same lantern twice cancels out. Par is the fewest taps that solve the puzzle (6–8 on weekdays, 9–11 at weekends). It’s worked out exactly and checked against all 33,554,432 possible sets of taps, so par is always possible and never beatable.
