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!!!!

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!

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

Freezes and crashes a lot

I really enjoy these puzzles, but as with a lot of people it continuously crashes. I have to restart the app for it to work again only to find that most of my progress has been deleted and then I have to restart the game because I can’t work out where I am up to. I had a look at the new educational game, however do not find it challenging enough. Hope you guys come up with a solution

It is a well formed app, which makes it so sad for me that it freezes and crashes most of the time when I try to submit my solution for checking. When I restart I have to start again from about half way through.

Developer Response ,

Hi, I'm sorry about these crashes. They seem to be related to hints and Apple's latest updates but we've been unable to find a fix 😢 (hmm ... perhaps also related to internet, as most reports are from outside USA where the server is...). HOWEVER, we're working hard on a complete replacement for the app and have released it first for our Education Logic Puzzles. We also made that app free so everyone can try it. There are 100 puzzles there of a full range of difficulties, so please give that a try: You can also reach us at anytime.

Thanks, Mike @ Egghead Games

Why it Hangs Up

On a very bad internet if you ask for a clue and the App cannot get a clue because of timeout, dropped packets etc, the app will hang. Don’t ask for clues and you never have a problem.
