Logic Grid Puzzles - Word Games For Brain Training

By Ross McNamara

This app is only available on the App Store for iOS devices.


Long before Sudoku hit the scene there were Logic Grid Puzzles. Developed by Lewis Carroll (besides writing Alice In Wonderland, he was also a mathematician and logician), these logic puzzles rely on deducing a complex solution from only a few pieces of information! You're probably thinking, "Whoa, that sounds really nerdy!" And you're right. But it's also really addicting. With only a few clues, you'll be able to fill in the entire 6 grid puzzle after you put your brain to work.

Plus, these types of word problems and logic puzzles are showing up with increasing regularity on standardized academic tests like the SAT, LSAT, MCAT and GRE. So beyond just being a fun past time, they're also a great way to prepare yourself for higher level learning.

The app is free, and includes a starter pack of puzzles so you can see if Logic Grid Puzzles are your kind of fun. If they are - there are already more packs with many more puzzles in place you can purchase from within the app - and I'm hard at work writing more puzzles to add in as soon as possible.

Sudoku and Ken Ken puzzles are fun, but I think you'll agree that solving word problems pushes your brain in ways those math based puzzles don't!

What's New in Version 1.5.3

Minor update - just a few small tweaks to the new Booya Pack. Changed clue #1 in the 'Resumés' puzzle. And fixed a few other spelling errors. Thanks to Christina for pointing these out!

As always, if you get stuck on a puzzle, or have any other questions or concerns you can email me at

Thanks for all the great feedback and reviews - it really helps!!!

Customer Reviews

Best Puzzle Ever, and I hate writing reviews.

This is by far my favorite app right now. Listen, I never write reviews- not on the App Store, not for products I buy..I just don’t really think it’s worth my time tbh. I won’t publicly endorse a product unless I use it exclusively and I really believe in it. My only official recommendations are US Army-issued moustache trimmers, Morton’s Salt, and the CR Laurence Fein two-inch axe-style scraper oscillating knife blade. But this app is incredible. I’m a philosophy major, and this app has boosted my reasoning abilities out the wazoo- well, I’m not a genius now, but it’s definitely made my class easier. If you’re looking to go to law school and take the LSAT (or sometimes the SAT/similar tests have stuff like this), this could really help you out. The stories are entertaining and make it a little easier to separate the premises, and I showed it to my professor and he loved it. 10/10 would recommend; logic is a skill many have lost.

My favorite app!!!

I don't write reviews often, but this app is so great I had to! The puzzles are challenging and engaging which I love! I struggle to find apps that entertain me and keep my brain engaged, and this one does not disappoint!! The clues are funny and I often show them to my husband who also thinks they are quite clever. I love the differing levels of difficulty and am so glad I bought all the puzzle packs available because I go through them rather quickly! I would definitely recommend this app to anyone who loves logic puzzles!!! 😀
**Small side note, other people have commented that autofilling the rows once an answer is true would be nice, but I prefer it without. It allows more room for error so I feel like I have to pay attention more. So maybe if it gets added someday it could be something in the settings you can turn on and off.

10/10 would recommend to a friend

I love this app! The puzzles are fun and interesting, some harder than others, and funny. I find many of the clues and scenarios to be hilarious. I often screenshot the clues and show them to my friends because I enjoy them so much. Whoever wrote these has a great sense of humor, or at least one very similar to my own. And there are even Easter eggs in some of the clues, which makes me enjoy them even more! My only complaint might be that I enjoy them too much and I go through the packs very quickly!

With the added bonus of feeling like I'm studying, or at least doing something close to studying- what's not to love?!

But the jokes, the jokes are so funny. They make my days brighter, so thank you to whoever wrote the clues!
