Flowjar
Pipe puzzle · Liquid physics
Liquid falls from a tank, runs down a tangle of pipes and fills the jars at the bottom. You control the valves. That is the whole game.
The catch is that a jar only counts if everything in it is one colour, and there is no undo for a jar: one drop of the wrong colour and it is spoiled. So Flowjar is not a reflex game. It is about reading the tangle before you touch anything, working out where each valve sends its liquid, and choosing the order.
The liquid is simulated, not animated. It pours, it splits at junctions, and it fills a jar from the bottom up, and it does not wait for you. There is a clock on each level, so the reading has to happen before you open anything. Open a second valve too early and two colours meet in a pipe you were counting on.
