Tap to flip
A tap flips the tile you touched and its four neighbours. Lit goes dark, dark goes lit.
A daily logic puzzle
Turn out the grid.
Tap a tile and the lights around it flip. Sounds simple. Then the board gets bigger, the tiles stop behaving, and you are three moves from perfect with no idea which three.

How it works
One rule, then complications
Not every tile plays fair
Bishops flip diagonals. Bombs take a whole 3×3. Walls refuse to move at all, and you plan around them.
Beat the target
Every board shows the fewest moves it can possibly be solved in. Matching it is a perfect. Most people don't, most days.
