Bones Chain
In Bones Chain you're playing a combination puzzle and strategy game that has you killing green zombies. Click on the floating zombie head you want to kill and bones will fly out in all directions, killing anything they come in contact with and sometimes ricocheting off the sides of the screen. Your job will start out easy: kill a certain number of zombies with just one hit. Then the blue ghouls come into play and you're not supposed to touch those. More and more challenges await you with every new level in Bones Chain.
