Oops! This is a great item!!!


The last part of this is my original review. My personal preference is to fill the whole thing in myself-psychological problem, I’m sure. Now, I make sure to not finish the top part first. Problem solved.
The answer was only incomplete because I didn’t scroll to the side. Learning curve. Sorry.
Thank you for the opportunity to rewrite this review.

Old review: Puzzle stopped before I finished. Answer listed by you was incomplete. Sort of a buzz kill. Puzzelus interrupts.

Developer Response

Hi! We obsess about quality of both the app and the puzzles, so I'd love to get more information about this. You can use Help – Contact Support, or email When the top rows of the puzzle are filled in, we mark it complete - perhaps that was the "stopped before finished" problem? The provided answers are often quite cryptic, but are usually complete, but we'd love to know of any errors so we can fix them!

I'd love to get some details if it's convenient - we actively support and improve this app and are releasing updates every week or two with customers suggestions and improvements.

Thanks, Mike @ Egghead Games

Need more options


I prefer the puzzles with more than 4 categories and after buying 3 packages I still haven’t seen any. I would rather choose which packages I pay for. It would also be great if we could make notes right on the puzzle to help solve it (ie, M or F and numbers to keep track of who’s who).

Developer Response

All the Penny Dell puzzles have 4 categories, and hence each "Add 30 Puzzles" will always provide puzzles of the same size (and always new puzzles of course). Of course if there's a reason to provide choice, I'm happy to do that, it just seemed a little redundant. Perhaps I'm misunderstanding? Yes, we are working on a way to add notes while solving the puzzle. It's a bit challenging due to the screen space required, but there is that white space at the bottom right, so we're thinking hard about it! If you have more comments, you can always reach me directly at and I'd love to hear anything else, or you can volunteer to test the first version with notes! Thanks for the review!

Love this app! But I can’t see it!


I love these puzzles and the app is easy to use and very stable and attractive. My only issue is that I have terrible eyes, so I sometimes struggle to read the column and row headers. It seems like there’s a lot of white space — a bigger font would be AMAZING! Please?

Developer Response

Did you know you can zoom the board (using pinch/zoom like a photo) until it is the "usual" size text for your device? We use the standard Apple font settings you've chosen for your phone/iPad, so if you can read other text, you *should* be able to read the puzzle labels too. However we do shrink it down initially to fit the display size so you can see the puzzle at a glance. That said, perhaps we can optimize the fonts further, as you suggest. You can contact me directly at if this doesn't help. We've put a lot of thought into the trade-offs for size and other accessibility features, so I definitely want to make sure we've hit the mark! Thanks, MIke @ Egghead Games
