Lights #708 is a 6×6 board at easy level. It starts with 17 of its 36 lights on, and the one solution needs 6 presses.

Row 2 is the brightest, with 4 lights on. If you chase from the top, that is where most of the work happens.

One corner light is on. A corner light has only two neighbours, so it is changed by just three presses: itself and the two lights next to it.

Easy boards often show the solution in the picture itself: look for a plus shape of five lights, which is one press in its middle.
