How do you play PourFlux?

Tap a tube to lift it, then tap another to pour. Liquid only pours onto the same color or into an empty tube. Sort every color into its own full tube to win.

Can a PourFlux level be unsolvable?

No. Every level is generated with a solver and shipped only if a full solution exists — if you are stuck, undo a few pours and try a different order.

How do I get three stars?

Finish at or under the level’s par, which equals a verified solution’s length. Undo does not reduce your pour count, so plan before you pour.

How to play PourFlux

Tap a tube to lift it, tap another to pour. Only the top run of color moves, and it only pours onto the same color or into an empty tube. The level is solved when every color sits in its own full tube. PourFlux is Skorven’s free browser water-sort puzzle: 40 levels that ramp from three colors to nine, and every single one is machine-verified solvable before it ships — if it looks impossible, there’s always a line.

Tips & strategy

Empty tubes are your only workspace — never fill the last one unless the pour wins something concrete.
Pour to consolidate, not just to move: prefer pours that empty a tube completely or complete a color.
Before touching a buried color, check where its other segments are. If two are trapped under each other in different tubes, dig the shallower one first.
