What’s New

Version 4.6.6

Improves row, column and label highlighting. If you tap a label, zoom and tap a cell, it will continue to highlight the row/column. This makes it easier to keep your place when the grid is zoomed and was a recent customer request (thanks!). Removes irrelevant menu items.

Fun puzzles, great implementation

I love this style of logic puzzle and this is a really good implementation. I find the interface easy to use, and when I get stumped on some of the tougher puzzles I like that I can take a look at the solution notes to get a strategy hint (just like I used to be able to do by looking in the back of the puzzle magazine, when I used to buy puzzle magazines).

I don't always agree with the difficulty ratings, sometimes I blow through some of the "extreme" puzzles and get stuck for a long time on some of the "casual" puzzles! But that's not really a complaint. My only actual complaint is that I've gone through all the puzzle packs already! But I'm going to clear out a bunch of the puzzles I've already done, so I can do them again.

Much different from “Logic Puzzles”

This is an update to my previous review. I had correspondence with the developer which cleared up some issues I was having, and for that my rating has improved dramatically.
This Logic Problems app game is very different from Logic Puzzles. It has a different style and feel; the clues are sometimes a puzzle in themselves. Both games give a round of puzzles for free, you can try before you buy. Personally, I do not care for the style in this “Logic Problems” game. That said, the games are proofed by the puzzle supplier and other people are able to complete them - they are just too difficult for me and I find them frustrating, even at lower difficulty levels than on the “Puzzles” app.
I would also like to retract my previous statement that the developer had removed my poor review of his app. Developers are unable to do this.
So, if you enjoy this type of brain teaser I would say give it a shot, it’s a free trial, you only have to pay if you enjoy it and want more.

[Edited] Thanks so much for getting in touch. I'm glad we were able to chat. Yes, some people like these traditional paper puzzles (converted to screen format), while others prefer the newer ones available in my other app "Logic Grid Puzzles". Vive la différence. Thanks again for taking the time. Happy puzzling! Cheers, Michael

Poorly written puzzles

Deleting this. Would be fun if the Logic puzzles were, well, logical! These types of puzzles have to be carefully written and double checked to provide clues and make sense with each other and the story. That is literally the basis for it. So why on one game where you have to figure out where all the cats nap in their owners home, how old they are and how long he’s had them does the story say he hasn’t owned any cats for longer than they’ve been alive, but the age of starts at 3yrs old while the categories in the grid allow for him to have owned some of the cats for only 1 or 2 years?
This is just an exercise in frustration when the information being provided has not been double and triple checked for accuracy! You’re supposed to be able to rely on the information being provided, not have to wonder if it’s wrong. The point isn’t to trick people into failing with half-truths. Anyone who’s ever taken the LSAT knows how well properly and infallibly written these games can and need to be to solve them.

Hi, I OBSESS about quality, as does Penny Dell who provide these puzzles. The cat puzzle is hard, but it’s complete. The clues are sufficient and correct. The sample puzzles, especially, have been solved thousands of times. Email a screenshot to me anytime at and I’ll take a look if you’re stuck. Cheers, Michael
