Lights Out

Turn off every light, one connected little puzzle at a time.

How to play Lights Out

Tap a light to switch it and its neighbours above, below, left and right. Turn them all off.

A useful tip

Each tap changes its own light and its orthogonal neighbours. Tapping the same place twice cancels that change. The generated puzzles are solvable.
