Love the simplicity of the rules and the different challenges this game offers. Also: it never crashes... Ever.

I love this game! It's simple to learn, but tests your logical thinking. It's easy to pick up and play when you have a few minutes. My go-to when I have a few minutes.

I really enjoy deductive games. So I really like games that impose new constraints that force me to develop a whole new set of inferences to play them.

... and more challenging than you'd expect--in a good way. I often end up saying "I'll play just one more," and it turns into 3. ;)

I love this game, and it's probably my most played. I've restarted it a couple of times just so I could play it again.

Lots of free puzzles included, at 3 different levels. Interface is great and the app is reliable. Can't ask for more than that!

It's a fantastic logic puzzle, meets all my needs except it is often VERY drab to stare at. Some color options would brighten it up and complete the experience.
