About Heart Box

Professor Rat is obsessed with physics puzzles, so he built a robot named Robby. There's just one catch: Robby's battery is terrible. To keep him running, you'll need to cleverly interact with objects in each room, guiding him to the charger to complete the level. Pop, destroy, or move things with a click or tap. If solving puzzles isn't enough, you can even build your own in the Level Editor!

Physics Focus

Gravity, Rolling & Bounce: Use gravity, rolling, falling, rebound, momentum and object collisions to complete each challenge.

How to Play Heart Box

Use the left mouse button on PC or your finger on mobile to pop, destroy or move game objects. Place the square robot Robby in the red charging station to complete the level
