PLUMBY

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.
