Alchemy 2 is the second part of an interesting series of logic puzzles where you have to mix certain elements and natural phenomena to create others, then use those elements to create more elements, and so on.
If you mix water with fire, you get vapor, and if you mix water with a mountain, you get a geyser. Based on this premise, you have to try different combinations to get new results. As you mix elements and make progress the difficulty increases exponentially, as there will be more and more elements for you to combine.
All the elements you discover will be added to a library where you can look up how they were created and see a log of your findings. And if you get stuck, you can watch ads to get clues or use research points that you earn as you play.
Alchemy 2 is an interesting logic game that's clearly based on other games from JoyBits (Doodle God, Doodle Evil, etc.) and ends up being simple and direct enough to be enjoyed by anyone, no matter your age or condition.
