Drip Doodle: Paint Puzzle

You get one line. Draw it anywhere you like, then watch the paint fall.

That is the whole game. A tap pours paint, a jar waits somewhere below, and between them is whatever the level puts in the way. Your line is a ramp, a wall, a lid, or a bridge across a gap in the ground. Draw it well and the paint runs where you meant it to. Draw it badly and you get to watch exactly why it went wrong, which is usually the more useful of the two.

REAL PHYSICS, NOT A SCRIPT

Nothing is on rails. The paint is thousands of drops that pile up, run down slopes, spill over edges and find the gap you left. Boulders roll, fans push, ice is slippery, and a crate you did not account for will send the whole stream somewhere you did not want it. Every level runs the same way every time, so when something surprises you it is a thing you can learn rather than luck.

925 PUZZLES, EVERY ONE PROVEN SOLVABLE

Each level was generated and then played by a simulator before it was allowed in. If there was no line that solved it, it never shipped. Levels are also checked to make sure their obstacles actually change how the paint moves, so nothing in a board is decoration.

THE DIFFICULTY FOLLOWS YOU

Solve things quickly and the puzzles get harder. Get stuck and the next one eases off. A level you failed never becomes easier while you are staring at it, because that would be insulting; the game adjusts what comes next instead.

COVER THE HOLE

Some levels start with the hard part done. Paint pours from a pipe onto a slope, and the slope carries it toward the jar. Then the ground ends. There is a gap between you and the jar, and every drop that reaches it falls in and is gone. Draw one line across the gap and the paint keeps going: over the hole, down the far slope, into the jar. Miss either edge and the flow finds the hole anyway. It is the same single line you have drawn all game, doing a different job.

FAIR ABOUT ADS

Drip Doodle is free and shows ads between levels. There are none at all until you have finished eight puzzles, never more than one every three minutes, and never after a level you just failed. A single Remove Ads purchase turns the between-level ads off for good. The optional ads you choose to watch in exchange for a hint stay available either way, because that is a trade you asked for.

Nothing sold changes the physics. Everything for sale is either cosmetic or the absence of ads, and every puzzle is reachable without paying anything.

Draw one line and guide the paint into the jar. 1081 physics puzzles, every one proven solvable by simulation before it shipped.

Every obstacle now does a job: bars send the stream one way, fans bend the paint in mid-air, bumpers throw it, portals move it across the board, and spikes wait where a half-drawn line would leave it.

New in the shop: line styles, jar characters and a night theme, bought with coins you earn by playing.
