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.

Customer Reviews

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.

Really fun and great functionality

These puzzles are more challenging than the quick logic puzzles made by egghead, but they're also really fun. It's like having a snack versus having a full meal--both great, but for different things. The functionality of the app is great. I love the auto fill of the Xs when you double tap an O, the back button for the fumble finger moments, and the erase errors button for the times when I'm just not sure if I'm on track. Great app!

Great game!

Love that you can choose different difficulty levels for the same scenario! There are many helpful features such as the hints and the "erase errors" button. I highly recommend this game for people of all ages who enjoy a good challenging logic puzzle.
