Little Alchemy. A game that gives you four elements: Earth, Air, Fire, and Water. These are your four basic elements that begin a combination that will grow to over 500 current combinations. Mix Earth with Water and create Mud. Mix Fire and Air and you make Energy. Energy and water will then lead to Steam. Earth and Fire gives Lava. Before you know it, you have 99 looking for one more....then you CAN NOT STOP YOURSELF. I'm Sorry. If you want to cheat, there are hints out there but I won't link you to them. If you get them all, let me know. We'll make a 560 club!
