It is way more fun having 3 dragons match up and attack your enemy, instead of matching 3 bubbles and getting points. 

There are rpg elements, pieces get stronger, equipment give special bonuses. 

Perfect for an iPad. Easy to learn, difficult to master, but not too steep a curve and just enough new pieces add to keep the challenge interesting. 

I just started playing recently, I really enjoy it so far. I had a busy weekend and couldn't play too much but I should be able to play later tonight. Considering the fun I had with my short time so far I'm really stoked about playing later.
