The highest rated app for classic grid Logic Puzzles! Decode written clues & fill the grid to solve them. 50 grid-based logic puzzles ranging from intermediate to expert solving ability. This modern solver has Smart Hints, multi-level Undo and the Auto-X features make it easier and quicker to focus on the logic. Keep short notes along with the puzzle to help you make your way to the solution. 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 2-6 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 in Version 1.12.11

We fixed the "large text" problem on iPhone 6S and 6S Plus phones -- thereby completing a company-wide New Years resolution!
We also added two new volumes (Volume 6 Casual & Extreme), though many of you will have seen an update for those already.

Please leave a review, or tap to quickly re-post your previous review. We don't nag in the app, but we're thinking about changing that policy because so few people leave reviews and because of the way Apple juggles the App Store listings, it really does make a difference. Prove the cynics wrong and thanks in advance!

Best logic puzzle app

I really love the features of this app. The puzzle themes are fun and there's a huge variety with varying difficulty in each theme. You have the option to change the color scheme from bright, normal, night time - which for me is great because I like to do a puzzle or 2 before falling asleep. Other great features include auto fill of boxes once you've placed an X, zoom in and out options to make the boxes larger or smaller, zoom in and out for clues to make the text larger or smaller, clues shown in a list so you can scroll between all available information easily, ability to cross out clues once completed, and add on puzzles (which are totally worth purchasing - you get a full set for 1.99) listed by difficulty level ranging from casual to challenging.

I've been playing this app for years and it's never disappointed. New puzzles are added from time to time. Also the developer people are very nice, friendly, and helpful. I've only written 3 app reviews ever and 2 were for Egghead games.

Bottom line: There's no better logic game app available.

Fantastic logic puzzles.

I've been playing this for a long while and finally decided to review it. I don't often review things so it takes a lot for me to do so. This is a fantastic set of logic puzzles and the new update fixed the large text issue on iPhone 6s. All puzzles are possible to complete with no guessing, and after months and months I finally can do the extreme puzzles under the expert time.
Each puzzle has multiple levels of difficulty and the starter pack has a good mix of easy and hard. I've downloaded a few extreme packs and they are well worth the money. Thank you for this app!

Best logic puzzle app!

I love the puzzles, I've bought all of them, although at this point I'm only buying the "extreme" ones because they're the more challenging ones. Never have any issues with the app, just wish there were puzzles added more often and that they weren't so similar to one another. The clues kind of have the same "pattern" if you will, so now that I've gotten used to it, I fly through them fairly fast. Regardless I'll keep buying them because I love logic puzzle Solving!
