Updated updated review:
Found that if you sit in a quiet room with no distractions, the puzzles are easier to solve. These definitely are challenging puzzles, but helps to keep our brains actively thinking!

Updated review:
Great customer support. Like that this version doesn’t “time shame” you. Glad to be reminded of where check your answer icon is. Like the note section. It’s the way I would work solutions when solving the magazine versions. Would like a variety of challenges available in purchased puzzle packs (4x4, 4x5, etc.) or know what is being purchased. Sometimes the wording is not always clear whether the statement is true or should be eliminated. That is brain frustrating and my only real complaint now that developer has responded.

Previous review:
Hard to follow. Not easy to check whether answers are right or wrong and erase wrong answers because no buttons to check that as with previous version. Not as much fun. Guess I will stick with my Quick Logic version and erase & replay and/or work daily puzzles. 👎

Developer Response ,

Hi there, thanks for the review. The “lightbulb” 💡button at the bottom right will check for errors and optionally erase errors. So, I think everything you loved about the old version is still there! 🎉

If you have more questions or comments, you can reach us anytime via email at, or Facebook.

Oops! This is a great item!!!

The last part of this is my original review. My personal preference is to fill the whole thing in myself-psychological problem, I’m sure. Now, I make sure to not finish the top part first. Problem solved.
The answer was only incomplete because I didn’t scroll to the side. Learning curve. Sorry.
Thank you for the opportunity to rewrite this review.

Old review: Puzzle stopped before I finished. Answer listed by you was incomplete. Sort of a buzz kill. Puzzelus interrupts.

Developer Response ,

Hi! We obsess about quality of both the app and the puzzles, so I'd love to get more information about this. You can use Help – Contact Support, or email When the top rows of the puzzle are filled in, we mark it complete - perhaps that was the "stopped before finished" problem? The provided answers are often quite cryptic, but are usually complete, but we'd love to know of any errors so we can fix them!

I'd love to get some details if it's convenient - we actively support and improve this app and are releasing updates every week or two with customers suggestions and improvements.

Thanks, Mike @ Egghead Games

Orange rocks! ,

I’ve been looking for this!

Ive always loved logic puzzles and I’ve been looking for some that make me think. I’ve downloaded different apps but never liked the layout and features, however this one is very user friendly and is my new and only go to. I love that i can check my answers as i go and the clues were just enough to get your board started but i had to use a lot of actual logic to really solve it. I’ve enjoyed it so far!
