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.

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.

The game features a unique fingertip cursor which enables playing large puzzle grids with ease and precision: to fill a square, move cursor to the desired location and tap anywhere on the screen. To fill multiple squares, press and hold fingertip until cursor fills the square and start dragging to neighboring squares. The game also enables locking the rulers, a powerful feature helping focus on one row and column at a time.

For more fun, Conceptis Pic-a-Pix 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 :)

I am addicted to pixel puzzles, and have been since they were introduced in Games magazine (about two decades ago). I’m serious! And Conceptis makes most of the best puzzles, which is probably why Games magazine has featured their puzzles so often. They also make the best app for pixel puzzles.

This app game would have earned 5 stars from me, but for two issues I have with it. It is not set up like the online Conceptis Pic-a-Pix puzzle play. I would especially like to be able to pick a column and row highlighter color that works better for me, and to be able to put my finger or stylus on the squares I wish to twocolor). Another reviewer wrote that the puzzles are a bit too expensive, and I agree that some do seem a bit too costly.

I am delighted that Conceptis made an app to satisfy my “addiction” (except for my two fairly minor issues. Thank you, Conceptis!
