Find the way clues are linked, paint the paths and discover a hidden pixel-art picture! Each puzzle consists of a grid containing clue-pairs in various places. The object is to reveal a hidden picture by linking the clues and painting the paths so that the number of squares in each path equals the value of the clues being linked together.

Link-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 features a unique fingertip cursor which enables playing large puzzle grids with ease and precision: to create a link, press and hold fingertip anywhere on the screen, wait until cursor fills the square and start dragging to neighboring squares. To delete a link, double-tap or use the eraser button above the puzzle.

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

Super Fun!

I love these puzzles! I think I might be addicted to them. Lol. There is a good variety of sizes and subjects. The puzzle solutions are creative and sometimes a little humorous. My favorites are the Famous Masterpieces series and the Bestselling Books series. It's so much fun turning a screen full of numbers into a cool picture and it's fun trying to guess what the picture will be as you work through the puzzle. There are a few similar apps but this one is by far the best of them!

There are free puzzles in intro packs, along with a weekly free puzzle. If you choose, you will spend 2.99 to 5.99 for new packs of 20 puzzles. These will last a good while. It’s a low price for the hours of relaxation you will get from these puzzles. One last thing, if you struggle with anxiety and difficulty unwinding at the end the day like I do, these puzzles will help relax your mind and ease your anxiety. Give them a try! You won’t regret it!

Ahhhhhhh this app is za BEST ,

Great game!

I LOVE this game. There are only two annoyances that keeps popping up for me. The controls are kind of difficult, because if you want to drag a link back, well… you have to DRAG it back. And I play with the game very zoomed out, essentially making it more difficult to play. And, of course, my second issue is that after you play a good week or so, you have to buy the new level packs. With money. From the real world. I am already retrying old levels just to have something to play on this game, because I am NOT getting my parents to spend money on this. But aside for these two details, the game is worth it. Thanks for reading this review!

Great puzzle, well made app

The same high quality puzzles from Conceptis I've enjoyed in book form are a real joy to solve in digital form as well! I find Link-a-Pix puzzles just a little easier to solve than some of the other picture puzzles from Conceptis, which is nice for the moments I don't want to concentrate quite as hard. The controls are intuitive and easy to use. I especially like the cursor mode which allows me to draw lines from off to the side without my finger getting in the way of the squares in which I'm working.
