What’s New

Version 4.2.12

Detects and provides hints for any unused "transpositions" on the board. These are a "mechanical" hint based solely on the current board position, but they are commonly overlooked and a useful aid to solving. (See the link the User Guide for solving logic puzzles and look for the Transpositions section for more information.) Also, an accidental tap of the Hint button will no longer cost a hint, and finally there is a new feature to report on mistakes without clearing them.

Cheers, Michael

Fun puzzles, great implementation

I love this style of logic puzzle and this is a really good implementation. I find the interface easy to use, and when I get stumped on some of the tougher puzzles I like that I can take a look at the solution notes to get a strategy hint (just like I used to be able to do by looking in the back of the puzzle magazine, when I used to buy puzzle magazines).

I don't always agree with the difficulty ratings, sometimes I blow through some of the "extreme" puzzles and get stuck for a long time on some of the "casual" puzzles! But that's not really a complaint. My only actual complaint is that I've gone through all the puzzle packs already! But I'm going to clear out a bunch of the puzzles I've already done, so I can do them again.

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.

Cheers, Mike @ Egghead Games

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
