Conceptis Fill-a-Pix – Many hours of mentally stimulating entertainment

[Game] Conceptis Fill-a-Pix

Conceptis Fill-a-Pix  Fill-a-Pix are exciting logic puzzles that form whimsical pixel-art pictures when solved.

Challenging, deductive and artistic, this original Conceptis puzzle offers the ultimate mix of logic, art and fun while providing solvers with many hours of mentally stimulating entertainment.

Each puzzle consists of a grid containing clues in various places. The object is to reveal a hidden picture by painting the squares around each clue so that the number of painted squares, including the square with the clue, matches the value of the clue.

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 features a powerful Smart-fill cursor for quick, single-tap filling of all remaining empty squares around a clue.

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, Conceptis Fill-a-Pix includes a Weekly Bonus section providing an extra free puzzle each week.

Conceptis Fill-a-Pix user reviews :

I’ve been playing this game for quite a while and really enjoy it! There are puzzles of different sizes and difficulty, so I can always pick the right one for me in the moment! I do really wish there was a “dark mode,” though, that would invert the colors or do something similar so the board wouldn’t always be so bright. I like to play the game before bed, but it’s not exactly relaxing having a super bright screen in your face.

  • Thank you for your comments. Dark Mode feature is on our list, and we hope to add it to the app soon.
I love this game but the Advanced Logic puzzles are literally impossible. I even referred to the hint page on how to play the Advanced Logic puzzle but that seriously didn’t help at all. It literally only shows you ONE instance of Advanced Logic using a 3 and a 5 and that Advanced Logic doesnt occur ANYWHERE on the actual puzzles, let alone in the corner. Any help more useful then the terrible hint page on the app would be nice.

  • Advanced Logic puzzles are extremely varied and it’s not possible to provide hints for all possible combinations. In case you get stuck on a puzzle, please send us a screenshot to support[at] and we will explain which next step you can take.

Brilliant game for losing time with. Only game I ever buy. Each puzzle gets you thinking in a different way. Levels for everyone and every amount of time you have from minute to hours.

Challenging but satisfying logic game. The finished picture at the end is surprising and amazing. I also appreciate that there are no ads that pop up.
