Takes concentration – Tic-Tac-Logic: X or O? Review

This game is great. I've learned several strategies to make the puzzles easier. I play this game on my iPhone 5 and iPad 4 at least once a day for the past 6 months. I've only bought one extra game so far bc I just play the same puzzles over and over again (I don't remember them since they're just a series of Xs and Os).
