The Alchemy puzzle is used to provide work for paints, (used to redecorate ships and building interiors) cloth dyes, enamel for swords, and potions. It is the crafting puzzle for the Apothecary. It also produces paint brushes. It was the second puzzle added to the game.

The Apothecary requires Hemp Oil made at a distillery to produce its paints.

This puzzle is most easily controlled by mouse. Left-clicking rotates a section of pipe counter-clockwise, and right-clicking rotates a section of pipe clockwise. When you are ready to see the results of your work, press the fill button.

• When making a path, keep in mind that the flow is generated by potion being pumped through the pipe, not by gravity, so if need be, you can double-back.
• Don't let flows cross unless you want them to mix! Be VERY careful about letting your paths branch off.
• The secondary colours mix like paint, not like light. So yellow and blue make green, blue and red make purple, and red and yellow make orange.
• When you make a secondary colour, (when you mix two colours) the new colour flows back upwards. This is because the potion follows ALL available paths. This means you cannot branch off a blue potion to fill a blue beaker, when you also need to make purple or green. Your blue beaker will end up smashed.
• The goal is to reach as many beakers as possible in one fill. Pou have unlimited time, so feel free to experiment to the full potential of your board. At the moment this is only a guess, but secondry colours ought to logically give you more points than primary ones.
• When there are two pieces in one grid zone, both are rotated at once. There is no way to change their rotation relative to each other.
