Exercise your brain and train your logic with tens of frustrating and exciting hand crafted levels of this classic logic puzzle redesigned expressly for a great Apple Watch experience and reinvented for a new youth on your iPhone.

Based on the idea of the classic Lights Out, the first native iPhone game, but reinvented with new challenging obstacles and added difficulty. All you have to do is aim to clear out each board by tapping on its cells. Be careful, when you tap one cell it will switch its color as well as those of its four neighbours, for better or for worse.

You'll need to plan your moves carefully and try to stay below each level's limit of moves. And once you get the hang of it, new challenges are ready for you with tricky new cell types that bring a new level of complexity that will exasperate, frustrate and obsess you!
