Again, you need level select. The entire game shouldn't have to be played in one sitting, especially when there isn't any indication of how many levels there are. Otherwise, it would have been a good game. Nothing new, but decent for match 3.
Too many problems! First, I started getting blank spaces, then the next chest woudn't open after I completed the sixth. To top it off, my game reset after the sixth chest. I wanted to like it... :(
I used alot of in-training items to raise my stats. It seems you can use as many as you want as long as you have enough money. My stats were almost all full. I think that is what helped me win the LittleGiant Cup.
