Learn and enjoy Logic Puzzles with 100 unique puzzles of increasing difficulty and multiple sizes. Decode written clues & fill in the grid to solve each puzzle. Work your way up from from beginner to master! Use the unlimited Smart Hints to see exactly which clue applies to the current board and why. Start with small 3×4 puzzles and challenge yourself with huge 4×7 cell puzzles.

Smart Hints examine your solution so far and explain how to fill in another cell by referencing your current board position and telling you what clue to use next (internet access required).

Other features include Auto-X for faster entry and multi-level Undo. These make it easier and quicker to focus on the logic! If you're completely stuck, you have the ability to check the grid for errors.

There are never any ads or nags or gimmicks. The app supports iOS iCloud sync and accessibility features, including VoiceOver, Larger Text and Dark Mode.

If you run out of puzzles and want more, there are multiple "100 packs" of new puzzles available for purchase. These are in the same size & quantity as the original free puzzles: 30 each of 3×4 & 30 3×5, and 10 each of 4×4, 4×5, 4×6 & 4×7.

Alternatively, you can purchase an Unlimited Puzzles monthly subscription for $4.99 USD per month (or similar for your country).

Subscription payment will be charged to iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Account will be charged for renewal at the same price as the initial month within 24-hours prior to the end of the current period.

I have all of their games. Someone said they didn’t like the new look (vs Quick Logic). Hmm. I think it’s attractive. I’d say, though, that there’s a lot of scrolling involved (sooo tiring) to see all the puzzles. Quick Logic has them organized into volumes and groups, which I like. I also prefer getting a gold or lower metal than nothing on this app. Gives an incentive to replay when done with all puzzles. Not sure why I’m typing this here. I guess I’m asking for more puzzle organization. I’ve bought all 16 (you’re welcome) puzzle packs of Quick Logic... glad to have fresh new puzzles with different stories.

Developer Response ,

Update: Thanks to your feedback, we now group the puzzles by size/difficulty, so the scrolling should no longer be necessary 🙌. (And we have more improvements coming!

Original: Thanks Ashley, this is the sort of feedback we love and will definitely address!

We're working hard on adding trophies as I write this. Reducing the scrolling by adding filtering is on our real-soon-now list as well.

Thanks again for those supportive words – and your purchases! Note that ALL the puzzles in this app are new - none will be repeats from your previous Quick Logic purchases. Yes, we have lots more stories too, so they won't repeat nearly as often.

Feel free to email me directly anytime at, or find us on Facebook, Twitter etc. if you have more ideas or comments.

Cheers, Mike @ Egghead Games

Love the different levels of difficulty but

I love that there are so many different levels of difficulty but I wish that checking your answers wasn’t considered a hint. I don’t want to know what I got wrong, just that something is wrong. It’s more difficult to figure out where I went wrong after the entire board is filled out. Also, a way to mark a box as a possible answer would be nice as well. • for true, x for false, and maybe a ? for maybe. I think that would help a lot!

Thanks! A quick note that we’ve added the change you suggested to only find out if there are errors and not always provide a hint (a couple of months ago). Thanks for pointing that out! I like the idea of marking a cell as “?” – something along those lines is in the queue. Cheers, Mike

New design is awkward and not enjoyable

I don’t know why the new design has a scrolling hint screen on top and a fixed screen at the bottom. It feels like playing with a broken puzzle, especially how close the bottom of the puzzle is to the bottom of of the screen.

Very user-unfriendly. I’m deleting and will try back in a couple months to see if the layout has been improved (or just changed back to the previous, much better Kaylie).

Hi, thanks for taking the time to leave feedback.

Yes, it is a bit different from the previous layout, and may take a little adjustment. The goal was to improve things not make it worse 😕, so I’m sorry to hear it’s not working as well for you.

Note that the board is not fixed, and can be moved down to expose more clues, in case that is preferred. Or, another way to make the more use of the screen is to rotate to landscape.

Please email me at if you’d like to discuss this further. I’m determined to improve this, so if you have other ideas, I’d love to hear them. Thanks, Michael
