Help me spend $10k to make our app profitable (itunes.apple.com)

Hi hackers. I posted fews months ago a blog post that had so much interest from the community: https://news.ycombinator.com/item?id=5067709 It was about how my previous app was a flop and wasn't able to get enough traction (0$ in 3 weeks). I got a lot of feedback from everyone here and learnt fews lessons the hard way.

Now let me introduce my new app: Boggler. Boggler is a variant of Scramble with friends and Ruzzle.

Contrary to the previous app (when I didn't have any marketing budget) this time I have $10k. I know that money ain't everything, but I guess it can help a lot.

So I need your help on a few things :

1. Any feedback on the app itself 2. How can I wisely spend that money to be profitable: Got fews ideas I can share if anyone interested. 3. Help me get some traction.

Thanks! And you're all awesome.
