Chute

A hopper pours grey parts and a bin wants red ones. In between there is nothing, and a part only travels on a part. Tap a chute into a cell and the part falls through it. A painter turns it red, a ramp turns the stream, a splitter deals left and right, a mould changes the shape, a filter sorts, a merger stacks one part on another. Nothing is dragged or wired. When the line is built you press Start and watch it run: a spilled part is lost, a slow machine just makes a queue, and a hopper that pours faster than one painter can keep up is the cue for a second line.

96 levels in eight wings, each adding something to build and something the floor does: mixing paint, wear and repairs, lifts and pipes, power cuts, grime, pistons, fans and a robot arm. Every level scores three stars and up to 1000 points, a Daily Shift deals everyone the same order each day with a streak for coming back, and a crew of eight characters complains when poked. No lives, and no clock until you press Start.

Plain HTML and JavaScript drawn on a canvas, no build step and no dependencies, in English, Russian, Spanish and Brazilian Portuguese. The simulator is deterministic, so every level ships with a stored solution that a test proves still works, and the same frames double as the store screenshots. One build goes to every portal through a thin layer for each SDK, ads and leaderboards. It is live on Playgama, with more portals to follow.
