5 STARS from KahiaL Way more puzzles than other apps! This game has way more puzzles than any of the other logic apps I've tried. Love that it has a daily puzzle too.

The game starts you off with more than a hundred free logic puzzles, with new puzzles added every day as part of our Daily Challenge feature. Enjoy a new, free brain-teasing logic problem every day direct to your iPhone or iPad or build your collection with one of our puzzle pack add-ons.

The Professor has even prepared a load of logical achievements for you to master - for example, can you beat him twice in a row, or how about five times? He thinks it is unlikely...

The gameplay is simple but addictive and Logic Puzzle Daily boasts all the latest logic puzzle features, including Auto X, Hints, Error Checker and Multi-Level Undo. For the harder logic puzzles you can use the Notes section to help you work through the clues and solve the puzzle.

These logic puzzles are all brand new and created especially for this app, not licensed or published before somewhere else.

Pretty fun but not five stars.

I love doing logic puzzles and do them all the time at home so I know what to expect. This app is fun and there are some good puzzles but I really dislike how they don’t tell you important info you may need. For example, if a logic puzzle is going to put in “Mr. —“ or “a boy wore purple” they usually tell you which name belongs to which sex. Most of these puzzles are made in England and have English names and dishes, and some of us who are not from England don’t know Basil is a boy’s name or if a certain dish has beef or not. Also, if you complete a puzzle but do not watch the entire ad after, the game erases your progress for your game. I understand if the game has ads but to erase everything you did because you didn’t watch an ad is insane. I do like the app though and I wouldn’t mind paying for other packs but $2 for 20 puzzles seems a bit much to me, especially when you can get an entire logic book for $5 with 100 puzzles in it. I’ll probably end up deleting this app when I finish all the free puzzles.

Also, with the new update that came out today (May 9th, 2018), things are zoomed in really strange for the iPhone X. I’m not deducting this from the app score but it is a current issue.

We have just put a new update live which fixes the iPhone X problems.

Pretty good

I just tried this app. I do a lot of logic puzzles and I’m always looking for new ones. The puzzles have been interesting and enjoyable. I would give five stars, if not for a couple of things. This is the only logic puzzle app I’ve tried that has ads, which is annoying. I see that buying a puzzle pack will stop the ads, so if I keep this app I will do that. The first thing that bothers me is that the timer doesn’t stop until all the cells are filled in, even if the puzzle has been solved. I wish I could just fill the grids on the top row, or the left-hand column. The other thing that bugs me is that there are punctuation errors. For example, the first puzzle I played had apostrophes in the surnames of all the couples. (Mr. and Mrs. Smith are “the Smiths”, not “the Smith’s”.) It doesn’t affect the playability, but it drives me crazy. If I delete this app, that will be the reason. If those two things were changed, it would be a five-star app.

Fun... if it loads

I love your app, and love logic puzzles. I like that there is a time to beat, but that you can take as long as you want to solve the puzzles. I really love some of the quotes said by the Einstein character, very inspiring!

I downloaded this app a week ago or so, and I bought one of the extended packs. Everything was going great, and I was enjoying it fully.

However, since this last update, I am having difficulties loading the game. It has the initial screen up with a message that comes up saying “loading puzzles, please wait.” No matter how long I wait, it never moves from that. I shut app down, restart, same thing. Sometimes I can open the app up and it loads everything instantly and plays fine. But more often than not, I am running into this loading problem. I just shut app down and restarted 20 times, waiting a little bit here and there, and it’s just not loading right now. I’ve tried restarting phone, no difference. I shut down other open apps and cleared my cache (something that seemed to help once before), and still no progress. What’s odd is it seems like it’s in the game, but not showing me anything besides this screen because I’ve tapped on it and then I got an apple store pop up asking me if I wanted to buy a puzzle pack.

I’m on a 6S iPhone (still works great! ;)
Please fix so I can rate higher!
