Casual Game Heartbeat Cup

Heartbeat Cup is a physics puzzle about guiding water into a cup. Water pours from a tap as fluid, splashing droplets, and your job is to get it into an empty cup by drawing lines and rails that redirect its flow. Because the water behaves like real liquid, you have to think about splash, momentum, and slopes — a steep drop makes it splash everywhere, so you draw gentle curves to tame it. You also have a limited amount of 'ink,' so you can't just wall everything off — the best solutions use short, clever lines and lean on gears, blocks, and other objects already in the scene. Across a hundred-plus levels it mixes in traps and moving parts that keep you experimenting. It's a satisfying, creative puzzler where there's often more than one way to fill the cup.

- Study the layout: Look at where the water starts, where the cup is, and any traps between them.

- Draw paths: Swipe to sketch lines and rails that redirect the flowing water.

- Mind your ink: Lines use limited ink, so aim for short, efficient routes.

- Fill the cup: Guide enough water into the cup to complete the level.

- Sometimes the longest route is the safest — don't try to block a fast, steep flow head-on.

- Draw gentle S-shaped curves to slow splashing water down rather than stopping it abruptly.

- Use objects already in the scene, like blocks or spheres, as pivots so you spend less ink.

- If water splashes over the cup, add a small buffer curve near the rim to funnel it back in.

- Mental: 65% — Figuring out how to redirect the water within your ink limit is a genuine physics puzzle.

- Healing: 55% — The gentle, experiment-freely pace and satisfying pours make it a relaxed game.

- Reaction: 25% — You can plan and draw at your own pace — it's about the solution, not fast reflexes.
