5 STARS by Totoro. Flawless Implementation of the Logic Puzzle on Tablets. This is exactly what I was hoping it would be when I purchased the game. I works exactly like the pen-and-paper version of the puzzles and provides a good spectrum of difficulty. The best feature is the ability to "remove mistakes" from the playfield. Since I never make any mistakes(lol), it can also be used to "reassure" you that you aren't going down the wrong path if you get stuck.

5 STARS by Suzy D. I've been looking for exactly this game for a year now. This type of logic puzzle was just waiting for a tech boost -- automatic fill-in, and no dreaded erasing! The interface is perfect: the controls are intuitive, and there's even a note section for when it helps to get your thoughts in order.

5 STARS by Mutation600. I've been waiting years for a decent Logic Problems app to show and its finally here. Used to play the old Dell logic problem books when I was younger and loved every minute of it. Great job guys!!!!

Logic Puzzles are popular preparation for the GMAT Logical Reasoning sections and similar deductive exams. Solve these puzzles to keep yourself sharp!

There are 10 backstories and five puzzles for each story that get progressively harder. The 5 puzzles for each story all have a unique solution, clues and statistics. See how your time compares!

Volumes 2-10 are available for in-app purchase. Volumes 2-6 each have another 50 puzzles with 10 new backstories and 5 puzzles for each story that get progressively harder. Volumes 6-10 repeat the backstories and allow you to choose harder or easier puzzles. These will provide HOURS and HOURS more fun!

New variations on each volume have multi-size grids, from 4 cell all the way to up 7 cell grids. Look for the "Casual" and "Extreme" volumes for these.

What’s New

Version 1.15.0

Fixed the "large font" problem on the new iPad Pros. Added more nudges to update to the new Logic Grid Puzzles app which has lots of new puzzles, automatically syncs between all your Apple devices and overall works better and is constantly being improved.

Removed Cloud sync and thus was able to completely remove the last remnants of Facebook's library from the app. iOS 11.3 or higher is now required.

Unfortunately it won't be possible to support this version forever. It is built on old technology that gets the job done, but is out of step with Apple's direction. I'm keeping it going as long as I can, but it's getting harder to do so. Please try our latest app: "Logic Grid Puzzles" and if it's missing things you like, email me at

Thanks, Michael @ Egghead Games

Super fun

I am a sucker for logic puzzles and I really enjoy having a portable version for my phone. I have only done a couple puzzles currently but they seem to offer a decent variety for the free version. The same problems have many levels of difficulty so you can do your favorite scenarios with more challenging prompts. Or you can start off with the easiest level and work your way up.

The only thing is that when you use the option to make notes, the app uses its own keyboard. I have an iPhone so it's not very intuitive to use a keyboard I'm not accustomed to. Maybe in the future they'll find a way to incorporate the phone's keyboard.

Other than that, it's a fun and entertaining app that keeps your brain sharp.

One Logic Puzzles app to Rule them all?

I’ve tried quite a few logic puzzle apps, and this one is my favorite. You get the most puzzles for free, and the additional puzzles you can purchase have 40-60 puzzles for $2.99 rather than a dozen or so puzzles at the same price.
I also like the time aspect and the ribbons you get if you beat the average or master time—it makes for more opportunities for replay.
My one issue is that on the harder levels, I have to use a pen and paper since it doesn’t allow note-taking. Adding that ability would make it pretty perfect! I’m still giving 5 stars though because it gave so many free puzzles and there’s no ads. Thank you!

Great app for logic puzzles!

I love this app! It's the best logic puzzle app I've had. It's very easy to use (though not easy to solve!). The stories are fun and different. They give you a good amount for free, and it's not too expensive to buy more (cheaper than a book of them at the grocery store!).

However, I've taken a star off because it needs an update badly. every time i finish a puzzle and tap to go back to the list of puzzles, it instead opens my web browser trying to allow itself access to my facebook profile. THIS HAPPENS EVERY TIME. If they fixed this, it would be a 5 star app

Developer Response ,

Hi Kristin, thanks for the update, and apologies for the ongoing problems introduced with iOS 11.x. We're busily working on a new version of the app but don't want to release it until it's done, especially as this one is still working for many people (though not all, like you :( ). Please give our "Education Logic Puzzles" a try in the meantime. We've made it free with 100 new puzzles, and it has the updated code that works perfectly with hints, and no hanging etc. We've also just updated "Classic Logic Problems" which has the Penny Dell puzzles in it.

If you'd like to be in the test group for new updates, or would like to talk directly for any reason, you can reach me at

Apologies again for these problems :( I hate when our apps have problems, but unfortunately we're in a weird place with this particular app, as it was built using technology that stopped being supported when Microsoft bought it, and then something in iOS 11 made it unstable. So it's really hard to know what's going wrong and even harder to fix it. This new version will fix all these problems once and for all, thankfully, as it is all being made with standard Apple tools. It just takes a while unfortunately, but we're getting closer every day.

Thanks, Mike
