About this game

Find the blocks, fill with color and discover a hidden pixel-art picture! Each puzzle consists of a grid containing clues in various places. The object is to reveal a hidden picture by dividing the whole area of the grid into rectangular blocks according to the rules.

Block-a-Pix are exciting logic puzzles that form whimsical pixel-composed pictures when solved. Challenging, deductive and artistic, these puzzles offer 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 block, press and hold fingertip on a clue, wait until cursor fills the square and start dragging to neighboring squares. To delete a block, 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, Block-a-Pix includes a Weekly Bonus section providing an extra free puzzle each week.

Fun logic puzzles. I wish you could do things at the edge of the screen without it thinking you want to go back to the menu, but that's probably a phone issue rather than an app problem. Also wish you could have uncolored blocks that aren't complete, or to connect / merge two blocks. All in all, great game, though!

Great game! However, the controls are a bit glitchy or they feel too sensitive. It would be nice if the zooming/scrolling could be a lot smoother. Another thing, there's only 2 puzzle packs that are free (out of 88?). 😞 Please give us more free packs. 😅

I love this game, I only play the "mega" packs with 100x65 puzzles, it is very relaxing (not hard, but satisfying to complete). However, the packs are very expensive. I buy one from time to time but I would buy a lot more if they were cheaper.

Thank you for your feedback, and we understand the price of the puzzle packs is not cheap. This is because all puzzles are hand made by professional artists making them very expensive to create. We hope to find ways to lower the prices in the future, and thank you for your understanding.
