Think-a-Bit

The goal of the puzzle is to first switch all the lights off and then switch them on back in as few key presses as possible.

Pressing the arrow keys (left, up and right) toggles the lights on the top row (left, middle and right) and also toggles some of the lights on the other rows following a "hidden" logic. you may figure out. Pressing "R" restarts the game.
