Train your brain with Dark Squares, the logic puzzle that tests your deduction and reasoning.

* one task: clear the board and turn all lights off - leaving only dark squares
* one rule: when tapped, a square will flip colors, but so will its 4 neighbours

Pay attention to the new special squares, and ponder your actions carefully - you have a very limited number of actions to solve each level.

Dark Squares is completely free for you to play - bringing new life to the popular classic puzzle Lights Out, keeping your brain in top shape and improving your deductive, analytic and logic thinking.

Nice game concept

Although the app screenshots weren’t impressive, this game proved to be a pleasant and unexpected surprise: a captivating logic puzzle with good looks and great gameplay.
The idea is to clear the board, by toggling off all the squares on it. The catch is that when you tap on a square, this will also affect its neighbours. So the order in which you tap on squares is quite important. The fact that you have only a few limited moves for each level (when you end them you'll need to start over) makes it a bit frustrating, but I guess that's the whole idea - you need to be careful with how you play each one, not unlike chess or checkers (simple rules with difficult emerging gameplay)


Wishing for logic

Enjoying the complex simplicity. Hoping for brain train while OCD time wasting.
