Heart Box

About Heart Box

In Heart Box, each level is a physics-based puzzle where you must get a robot to the exit. You interact with the scene by clicking, dragging, or tapping on objects such as boxes, planks, and switches. You do not control the robot directly: instead, you rearrange the environment, and the robot moves automatically once a clear path exists or when triggered. Your goal is to solve each layout in as few moves as possible.

The challenge comes from the limited space and the need to think several steps ahead. Objects tip, slide, and interact with gravity, so a poorly placed box can block the exit or send the robot tumbling backwards. Early levels teach simple placements, but later puzzles introduce multiple moving parts, timing elements, and objects that respond only to specific actions. The game rewards careful observation over guesswork, and the satisfaction of a well-planned sequence is what makes it hard to put down.

Tips to win

• Study the whole level before your first move; a single misplaced block can block the exit.
• Use the edges of the level to keep objects from falling off; wedging blocks against walls makes stable structures.
• If a solution isn't working, undo your last few moves instead of restarting; the problem is often a small placement error.
