About the game

PLUMBY is a pipe-rotation puzzle where water changes state on its way. Rotate the pipes to lead the water from the tank to every flask in the form it asks for: water or steam. A boiler turns water into steam, steam melts ice blocks back into water, a fan spun by steam drives motor pipes and opens valves, and a water generator powers furnaces and freezers. Unscrew bolted pipes with a screwdriver and smash rocks with a pickaxe. An endless mode brings in new elements one by one, five worlds of 100 levels each focus on one element, eight difficulty tiers go from Super easy to Impossible, and a daily challenge of 10 levels mixes everything. Chests, mascots and pipe skins to collect.

How to play

1Tap or click a pipe to rotate it a quarter turn.
2Connect the tank to every flask so each flask gets the state drawn on it: a water drop or a steam cloud.
3Steam spins fans that move motor pipes and open valves of the same color; water spins generators that power furnaces and freezers of the same color.
4Tap a bolted pipe to use a screwdriver, tap a rock to use a pickaxe.
5Fewer moves give more stars; use a hint if you are stuck.
