I am enjoying this neat little match 3 game. It has a nice progression where you earn coins and buy various upgrades as you beat levels and progress to harder ones (like most games ;-). It is free and, so far, no signs of IAPs anywhere. Worth a look!
Edit: there is a shop where you can buy coins with real cash, but I have not needed to at all. I have played quite a bit into the game and I am happy with how the difficulty is tuned. I continue to really like this one.
