A logic grid puzzle with a twist! Small logic problems use the same principles as larger puzzles, but are faster to complete and work well on phone screens. One free puzzle every day, or buy a volume of puzzles if you can't wait.

Great for new players, or seasoned players who want a quick game. As well as a free puzzle every day, this fully functioning version includes 10 graded puzzles and no ads. As always, there is NEVER guessing required, just logic. Smart Hints suggest a new square and explain which clue applies and why, based on your current solution (internet access required).

Solve these puzzles to keep your brain sharp! Logic Puzzles are popular preparation for the GMAT Logical Reasoning sections and similar deductive exams.

Optimized for screens instead of paper, this modern solver has smart hints, multi-level Undo and Auto-X features to 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 hint.

As well as the daily puzzle, there are ten puzzles arranged as two story groups each with 5 unique graded puzzles. Each logic puzzle includes statistics for its average completion time. See how your time compares! Each group has a range of puzzles that get progressively harder. Additional volumes are available for in-app purchase and more will be added regularly.

The best logic problem app out there


I LOVE this app! Logic problems are my favorite, so I'm always on the lookout for a good source of them. This one is the best! The clues are clearly written and never obtuse, and I so appreciate the functionality of how it's built. When you tap an O, the Xs auto fill. If you fumble finger and poke the wrong thing, you can just use the undo button to go back a move. I have found other apps that are lacking in some or all of these qualities, and it makes them more frustrating than fun. I have opted to buy a number of the puzzle packs and think the value for what you get is very good. They are just so fun. Keep the puzzle packs coming!

Logic puzzles


I like this puzzle app, I like that there are daily puzzles , but I sometimes have a problem getting the Saturday daily puzzle. I hope they fix the problem because the daily puzzles are only available on that day. It would be nice if the daily puzzles were available for the whole week that they appear, that way you can go back to the days you missed. But other than that it is a good game., especially if you don't have the money to buy puzzles. Thanks for this app. 🐱



I’ve seen what you’re doing with you other games and it looks HORRIBLE! Please please please don’t change the colorful formats and design of your current version!!!

Developer Response

Hi KBiz13, thanks for this feedback. It's a bit of a dilemma. Although I just managed to put out this small update to fix some crashing problems that started in iOS 11, it's really hard to update this app for various boring technical reasons, and we've put a huge effort into doing the new "pure iOS style" version of the app you've seen. Side note: have you seen the pictures we just added (in Education Logic Puzzles) to make it much more colorful? They're coming to Classic Logic Problems this week as well.

All that aside, I hear you (and others!) and understand that completely changing an existing loved app is not a good thing either. Believe me, this was discussed constantly as we worked on the new design. I'm currently considering keeping this app "as is" and adding new puzzles and features only to the new app and expanding its original goals. Then everyone can keep using the old, and also use the new when we get it to the level that makes it desirable to them.

I'd love to hear more opinions and discuss specific ideas. You can reach me anytime via email at if you feel inclined. It would really help us to clarify our thinking as we move forward.

Thanks, Mike @ Egghead Games
