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

So fun!

This is comically challenging for me. I’m constantly saying to myself “it’s ok, you’re good at other things in life” ... but that’s part of the fun in learning new things. Once I read the answer I feel better and excited to try to think through the clues differently. I think it would be cool if some of the answers had another layer of hand holding to help guide me through solutions a little more, and how I can think differently through areas where I probably got stuck.
