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. 🐱
