Paint squares as you solve the puzzle and discover a beautiful pixel-art picture! Each puzzle consists of a blank grid with clues on the left of every row and on the top of every column. The object is to reveal a hidden picture by painting blocks in each row and column so their length and sequence corresponds to the clues.

Pic-a-Pix are exciting logic puzzles that form whimsical pixel-art pictures when solved. Challenging, deductive and artistic, this original Japanese invention offers the ultimate mix of logic, art and fun while providing solvers with many hours of mentally stimulating entertainment.

The game enables zooming the entire puzzle, or just the grid area while keeping the clue-panes locked. Other features include a unique fingertip cursor for playing large puzzles with ease and precision, and a show/hide/lock rulers option helping focus on one row and column at a time.

To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

For more fun, Pic-a-Pix contains no ads and includes a Weekly Bonus section providing an extra free puzzle each week.

Great puzzles!

I’ve been doing this kind of puzzle for years. These are some of the best. This app includes genuinely challenging puzzles. You don’t have to spend money to try some harder puzzles. And after you get through them all, there’s also a free weekly released puzzle. I liked it so much, i did buy a couple of puzzle sets. I really enjoy this developers puzzles and I want to support him or her. (If you haven’t seen the other puzzles, you should really check them out... personal opinion, they’re all good.)
I like the interface... the way you choose color or lack of color is intuitive, and the ability to lock the row and column selector is a great feature I don’t remember seeing anywhere else. It’s epically usefully for the large puzzles.
I highly recommend this to experienced puzzle players.
Beginners, there are a few easy games and a set of instructions, but it puzzles get harder fast. I’d say try it. If you find the puzzles too difficult, check out any of the dozen or more competitive apps that have a full set if easy puzzles to warm you up, and then come back and try these again.

Fantastic game, I'm addicted!

FYI you get 42 puzzles free and one new free puzzle a week. Other packs cost like 2-3 dollars and come with like 20 puzzles. But they're so fun. And it actually has good pictures. I can't find other similar apps that make as good of pics or are as fun to complete. Also I love that there are themed packs—I bought a romantic theme and it had all these cutesy pictures of love and it was adorable! I would totally recommend this game if you like logic puzzles.

Edit: I do have one complaint about this game. I play it on a phone and primarily use my thumb, but the color choices are on the top of the screen, so they aren't comfortable to reach. The bottom of the screen is completely empty, and it seems like it would be a good idea to put the color choices down there where they would be easy and comfortable to reach. It's a little thing but something that's begun to irritate me after playing for a long time. I would love to see this changed in a future update :)

Best Picross app available!

I tried 10+ different Picross apps and this one is the best by far. There are hundreds of puzzles of varying difficulty levels to choose from and the controls are great. Cursor mode makes doing large puzzles on my small iPhone 7 screen totally possible. Other apps have terrible controls, lots of bugs, and their puzzles are way too easy because they have to fit on small screens. The Easy level in this app is like other apps' Max Difficulty level. Also, the developer updates this app and adds new puzzles regularly. Most other Picross apps on the App Store have been abandoned.

Minus 1 star because the pricing model is a bit expensive if you do a lot of puzzles. You buy puzzles in packs of 20 for $0.99 to $3.99 based on size and difficulty. I wish there was an option to get all the puzzles for a one time fee. Or at least more puzzles per pack. Relative to other apps and games on the App Store, these puzzle packs are expensive. But worth it!

Feature request: Dark mode or dark themes for playing at night!
