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.

Customer Reviews

Hours of Fun!

If you love logic puzzles combined with art, you will love these. I especially like the large, more difficult color ones. It's so satisfying to see the picture revealed after hours of thought and calculation.

The user interface has nice features such as error check, which tells you how many errors you've made, or shows the exact errors if you choose. I also love how it shows, with a touch, how many empty spaces are left between solved areas.

The only improvements would be to allow filling of a square directly instead of first having to place the box curser over it and less expensive puzzle packages.

Highly Addictive!

These games are so much fun and extremely addictive. I love watching a picture come to life as I figure out the puzzle. The colored are my favorite.

The only issue I have is that I'm playing these on an iPad mini and a lot of the puzzles I would like to play are so large that I can't read the numbers well enough. I wish there were more made for the iPad mini or that there was a way to enlarge sections of the puzzle as you work through it.

Terrible Interface

Were you guys trying to invent the worlds most cumbersome interface? Every mark requires multiple gestures. First you have to line up the double rulers to frame the square, then touch once to fill it in, then a second time to block it out and then a third to clear it. On top of that there is no way to lock down what you've done so it is easy to accidentally change marks.

It's a shame because Conceptus has high quality puzzles but there are much more usable nanogram apps on the store.
