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.

So fun and hint feature great when stuck

My favorite is the hint feature which explains why you can make the next deduction based on what you’ve already deduced rather than just telling you so you actually learn to get better- I love to start with the easiest puzzle in a series and work my way up so with each successive puzzle I get better at making deductions-This makes the app better than the books I used to do - in the books if you get stuck you have to peek at the answers- and might never figure out what deduction you missed- In the app you can learn along .
Also love the eraser feature- it tells you if you have made an incorrect deduction thus far- cant tell you how many times in the old paper versin I made one error and then had to erase whole grid- if you click eraser it erases just the incorrect deduction or confirms you have no errors- very helpful when you’ve just made a big deduction and dont want to continue without knowing its right
There are in app purchases but only for more addtl puzzle packs to play- not while you are doing the puzzles you own and the puzzle packs are only a few dollars each and easily if your an average solver will take 6 or more hours to work through a puzzle pack so its a great deal. A few bucks for hours of puzzles.
I always loved the books but this app is amazingly better than the books with the extra features-have tried a few logic puzzles apps but this is my hands down fave

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!
