I didn't play this very much at first, but I recently picked it up again and have really enjoyed the challenge...

Interesting puzzles, I especially like the really big boards. Well made, like all Conceptis games.

Iām still working my way through the medium puzzles, looking forward to the advanced. I really enjoy figuring out the solutions using logic. My only suggestion is that there should be a way to erase all the pencil marks at once.

Please make more. I want to stop replaying the ones I've already done. Please make some more!!!

Great game, at first glance you think it is too easy then suddenly you are totally stuck.

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).
