Lights out puzzle · Challenge 2

How to play

A corner changes three lights; an edge changes four. Tapping the same tile twice cancels that move.

Think about the neighbors.

One tap changes up to five stars. Try predicting the next board before tapping; the same tap again reverses that change.

Start with the board. Open a hint only when you need it. There is no timer: take the puzzle at your own pace.

Browser games are independent activities inspired by observation and playful problem solving; they are not levels from Silky Reveal.
