Heart Box - physics puzzles game

Tap, drag, and drop physics objects to guide a stubborn heart into a waiting box—then build your own contraptions.

I didn't expect much from a game called Heart Box, but the first time I tapped a wooden block and watched the whole stack collapse like a guilty Jenga tower, I was hooked. You get a heart—sometimes a smiling cartoon heart that looks mildly annoyed—and a box somewhere on screen. Your job? Remove or manipulate the physics objects between them so gravity does the rest. Blocks, ramps, balls, ropes, springs—each level is a tiny Rube Goldberg machine waiting to be broken. The trick is figuring out what to delete and when. Deleting a support beam might send a pendulum swinging into the heart, or it might drop a boulder on its face. I've restarted levels more times than I care to admit, not because they're hard, but because I kept thinking 'just one more tweak' after every failure. The cartoon characters you unlock are pure bonus. They don't change the physics, but they absolutely change your mood when the heart finally plops into the box and the little critter cheers. And then there's the level editor. I spent twenty minutes building a nightmare of spinning gears and stacked crates, only to realize I couldn't solve my own puzzle. That's the sign of a good sandbox. If you enjoy thinking with your hands instead of just clicking through menus, this one gets under your skin fast.

Use the mouse or touch to interact with objects. Complete levels and unlock all funny cartoons! Don't want to complete levels - make your own levels!

Tap objects to delete them, but watch the chain reaction—sometimes the first thing you remove isn't the real problem. Use the level editor early; building your own puzzles teaches you how the physics engine thinks. Experiment with timing: some objects need to be removed in a specific order, not all at once. Don't ignore the cartoon characters—unlocking them adds a surprising amount of motivation to finish levels. If a level seems impossible, look for hidden hinges or objects that only move when something else is gone. On touchscreens, use short taps rather than drags to avoid accidentally triggering multiple objects.
