Liquid Measure 3: Poison Pack
Smart Code's superlatively fluent physics puzzle has turned toxic, and this is a good thing. Really. Liquid Measure 3: Poison Pack transforms the pipe-building, fluid pouring, quantum teleporting and bombing you know and love, giving it a more potent purpose. Arrange the pipes, valves and other elements, then turn the start switch to direct glowing green liquids into their respective containers, measuring properly so you don't spill or waste any of the hazardous fluids.

As an expansion pack, it has the gameplay of Liquid Measure 3 only with 30 newer, glowier levels. You also won't find many instructions here and the challenge ramps up early on, leaving you scratching your head over seemingly impenetrable blocks while an increasing number of pieces forces you to construct byzantine plumbing to reach success. Although it sounds like a simple plan and each level can in theory be solved in less than a minute, Poison Pack is packed with enough experimenting and rerouting to tease your brain for most the afternoon.
