I'm sorry, but I'd always associated the elephant games with fun gameplay and challenges to your thinking. Not random chance and split-second reactions. 1/5 Insane police car.
Man, it seems like in the final level I get maybe a dozen copies and then it starts spazzing out. And yet I can play things like Balloon Invasion without any problems at all. Grr
Fun and challenging enough that I actually had to think, but not so hard that I had to bang my head on the wall for an hour over the one puzzle. And to think I actually attempted to draw the musical notation symbol with those lights. HA!
A-hah! I understand now. With the waves that come when the enemy castle is low, you're supposed to have offensive spells to thin them out. I guess all I need to do is go back and forth, capture castle, lose castle, capture castle, a few times until I level up enough to get an attack spell.
