There seems to be a lot of great, and usually cheap, games out there that get lost on the flood of apps. Has anyone tried Wallz? It looks like an interesting strategy game. There's one review on iTunes, but I think it's probably the dev trying to talk it up. Zone Warrior looks promising too. Enso Dot and Hexterity both look like pretty unique puzzles. Mastermind. I have this one, but I think it's overlooked. I keep it next to Imangi on my home screen with my "overwork my brain until I get a headache" puzzles. Metasquares. I have this too. As far as I know it's an original concept and it's very well executed. I know there has to be about a million more.
