Lanterns. One quiet room.

Tapping a lantern turns it and the lanterns directly above, below, left and right of it. Lanterns at an edge simply have fewer neighbours. The board is finished when every lantern is out.

Select a lantern with the arrow keys and tap it with Enter or Space. Tab reaches all controls.

Undo takes back a tap. Reset starts this board again; Next puzzle begins a new attempt on the next board.

Each board shows its par, the fewest taps that can clear it. A finished board earns 100 points at par, less 4 for each extra tap, down to 20. Undo takes back the board, never a tap already counted, so the count you see is the count that is scored.
