Every factory in Mixmatics has customer orders to fill. Place pipes from your inventory on the grid, turn them into position and route liquid from the sources to the order outlets. Press Run and the liquid moves one cell per tick; stop, adjust and run again as often as you like. Only your last run counts.
Mixers combine colours by recipe: red and blue make purple, red and yellow make orange, blue and yellow make green. T-junctions alternate between their exits, filters let only listed colours through, chambers heat, chill or polish a drop, and programmable valves open and close on a schedule. A contaminated drop fails the run if it reaches a customer, and an open pipe end spills liquid as waste.
Filling every order earns a star; meeting the efficiency targets earns two or three, judged on waste first, then energy, production cycles and your actions. The campaign has 200 levels in eight chapters, and a new Daily Challenge factory, the same for everyone, opens at 00:00 UTC. Every drop carries a letter as well as a colour, so colour is never the only cue.
