Whatever problems I had opening the app have been resolved, possibly by the restore I did. Great app!

The rules are simple, but some of the deductions are fiendishly challenging on the harder, larger puzzles. I love the interface and the way it keeps count of the number of X's and O's in each row and column. A polished, fun treat for logic fans.

Great game for short spurts of time, like waiting at the bus stop. It's easy to pick up where you left off, yet still engages the brain. Fun!

I like the game, but sometimes I can't tell which cell I'm clicking on, and I change the wrong one, messing up the board. A moveable cursor like in Fill-a-Pix would be helpful.

I love this game! It is worth every penny. I play this all the time and it is a great way to kill time. Got quite a few people hooked on it!

This is a new puzzle type for me and I'm really enjoying it. It also works well on the iPhone, unlike several of the other Conceptis puzzle games that have clunky, awkward interfaces. Skip the Conceptis version of picross for the iPhone and get this instead!

This is an awesome puzzle game. Great for anyone who wants to stay sharp and likes to think outside the box. I've never had any issues with the game, no bugs or glitches or anything and the extra puzzle packs are really reasonably priced. I'd definitely recommend this game to fellow logic puzzle lovers.
