LogiGrid Logic Problem Puzzles

By Harmony Applications

Open iTunes to buy and download apps.


Do you sometimes feel that you need a mental tune-up? Feel like your logical thinking skills aren't what they used to be? LOGIGRID Logic Problems are a challenging and fun way to develop your deductive reasoning and critical thinking skills. If you regularly do logic puzzles then you know how addictive they can be. If you're new to logic problems, they're simple to learn so you'll be solving them within minutes.

To solve LOGIGRIDs, you are given a scenario which describes the problem to be solved, followed by a set of clues from which you deduce the connections between groups of items such as people, places, objects, or dates. If you determine that a connection exists between the two items then you place a “dot” in the grid, if there is no connection then you enter an “X”. It's that easy!

Whether you have just a few minutes or a few hours, LOGIGRID's 20 original logic problems will entertain you while improving your ability to think and comprehend more clearly.


Runs optimally for the iPhone and iPad screen format.
Ease of use features include PROGRESS, UNDO, and AUTOFILL buttons.
Use in-app timer to challenge yourself and compete against others.

Customer Reviews

Good app.

Love the fact, as already mentioned, that it is simply what it is rather than daft graphics and sound effects. Works very well, ie when you go to fill in the puzzle the app zooms in all the while leaving the clue there. So when your brain is trying to remember five things at once it isn't over complicated by trying to remember that Emma is actually mrs Arnold and forgot to lock door but got there before jean who isn't mrs hunter! All in all I love it, it's not too easy, it's nice and challenging, however I would like to see a few more puzzles as I am nearing the end. But well worth five stars.

Love this game

I love how this app works it's simple to use and great fun, I have not experienced any glitches but I do wish they would update with more puzzles. I have played the puzzles about 4 times over and I am doing them again. It is easy to clear a puzzle and by the time you have finished the last puzzle and left it a little while you can replay without the fun being taken away.

I love logic puzzles

This is a great app, and is easy and intuitive to use, BUT
1. Is slow to respond: when I tap on 'autofill' or 'done' it takes several seconds before the app responds.
2. More puzzles please! I only downloaded it so have several puzzles left, but it won't take me long to finish.
3. The price is acceptable if there are new/more puzzles coming on a regular basis, but way too expensive if not.
