The Sandbox

In this game you try to complete certain tasks to get mana. If you are buying an element and you accidentally hit buy it now and don't have enough mana, it will take you a screen that you can't get off of unless you shut you phone down. This game is also bad because you buy all the elements you need, but you need more mana to go on! This game does have in- app purchases, but don't get it, in my opinion, those flaws are really big. It's a good game because it keeps you thinking. You also can create worlds for others to view In the gallery. You can view other worlds in the gallery, too. This game is free. It's rated 4+.
