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 Smart 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!

Note: Some reviews suggest there are logic errors. As far as we know, there are none. Contact us with a screenshot if you disagree, or get a hint, which will show which clue still has information for you to use.

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.

Tough love

When I first got this app it worked wonderfully. I loved getting fifty puzzles for free. They were a lot of fun and I enjoyed beating my times. I spent hours upon hours working on it, and I had just finished the last puzzle and was going to go back to redo some when it crashed. This had happened before so I didn't think It was a big deal, but when I went back to reopen it, it wouldn't work. It tried for a few seconds and then crashed. This was extremely frustrating seeing as I just finished the last puzzle, and I really want to go back in. Also, some of the puzzles were guess-and-check, which I didn't like. Although it provided hints, I wanted to solve them on my own and that was impossible for some. Please fix this!

Great Program!

This is a very well done program! The interface is quite simple to use and helpful. You can "cross-off" clues as you want to, and it automatically populates all of the "No" values in a column/row when you pick the "Yes" value. There's an undo which is helpful too.

My favorite feature though is the new Hint system, where it actually helps you understand what you missed, either a logical deduction, or going into some text detail about a Clue, walking you through understanding where you missed setting a value. This is something the old version didn't have, but a feature that is awesome!

Great app many levels, add more pls

This game is great for logic puzzle lovers. Many levels, timed so you can try to solve faster and beat the expert time. There are several puzzles with five non repetitive levels each. Can play over and over. I wish they would send more puzzles. Some apps have a weekly or daily puzzle feature, which would be great so the app doesn't end up in the trash. I highly recommend it to maintain longevity in the life of the app.
