What's a good iOS game for someone who thinks word puzzles are statistically satisfying?

Okay, so WordPix: Guess Word by Picture is this game where you look at a picture and figure out the word it represents. Sounds basic, right? But the interface is clean, the puzzles are well-designed (the graphs are actually readable!), and it hits that sweet spot of being challenging but not frustrating. It's like a spreadsheet...but fun! Plus, it’s got a 4.8 rating, so the data doesn’t lie. Finally, goodbye to Excel hell for a few minutes. I'd bet you could even analyze the difficulty curve of the puzzles; now *that's* a project. I could probably even build a script using the API to pull puzzle data and run some regressions. Now I'm getting excited!
