If you're completely stuck, you have the ability to check the grid for errors or get a hint.

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 2-5 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

PLEASE CONTACT US VIA EMAIL IF YOUR APP IS CRASHING: We need your help to fix these very rare crashes. Thanks!

* New puzzle sizes, from easier 4 cell to brain crushing 7 cell
* iPhone support
* Zoom support
* Updated design

We've made a lot of changes in this release. Please email us at if you have any problems at all! We will reply and we are planning to do a new release ASAP to fix issues that arise.

** SUPPORT UPDATE, 8:00am Monday July 28 EST **

Although a LOT of people have successfully upgraded and are enjoying new puzzles and the improved usability (thanks!), we have heard from you about some things in the update that you'd like fixed or changed. Below is a summary of what we know about so far and our plans.

CRASHES: Two emails about crashes suggest that the pattern is something like: upgrade, look at help, cannot get out of help, restart app, but it always closes. First try turning your device off completely ("red swipe"). If that doesn't correct the problem, a workaround is to completely uninstall the app and reinstall. BUT this will erase your completed puzzles. Please email us at if you've experienced a crash of any sort, especially if turning on and off fixed it.

VARIOUS: You can find your solve time in the center of the sliding star. Look for fireworks if you beat the expert time! We hear that you'd rather have the original white labels with black text for better readability. Music is muted when you start Logic Puzzles, but should keep playing. We'll change both of these in the next release.

MISSING VOLUMES: If you had purchased volumes but not played any puzzles in them, please choose Menu -> Restore All Purchases to re-enable your purchases. Thanks!

NOTE TAKING: We're looking into the following problems and will get them fixed ASAP: hardware keyboards no longer work, text jumps down to the line below when trying to add to a line.

Apologies for these and any other glitches. We will fix these. We take our puzzles seriously, just like you do! Thanks for your patience as we work through this. Mike @ Egghead Games.
