Black Hole Square

About Black Hole Square

Black Hole Square is a minimalist space puzzle game with one goal: clean up every square in the universe. Each board is a small grid of tiles, and tapping a tile makes it act. Arrow squares shove their neighbours in a direction, and black holes swallow whatever falls into them. Other tiles behave in their own peculiar ways that you discover as you play. Each puzzle gives you a limited number of moves, so you have to find the exact sequence of taps that leaves the board empty. The early puzzles teach one idea at a time, and later ones combine them into tricky chain reactions. Eighteen hand-made puzzles include three bonus challenges at the end. Swipe to reset, go back or skip ahead, and your solved puzzles are remembered on this device.
