like this game but....
i really like the 8 different difficulty levels (from "greenhorn 5x5" to "grandmaster 20x20") but it's not really clear that this app is one of those game apps where they give you 2 puzzles for each difficulty level but if you want more, you have to pay for game packs. i know part of it is my fault b/c i didn't read the more part but that's still the only thing that says it. there's no screenshots in the app store & doesn't say anything anywhere else. i downloaded this late last night & i thought maybe it was the type that added everyday. this morning i went to check, nothing changed & i noticed the shop icon on the bottom & it hit me.
