Find which neighboring squares must be painted and create a beautiful picture! 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.
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.
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.

Ratings and Reviews
Fun game, suggest adding a hint option.
UPDATE: Conceptis has updated the game to address the concerns noted below, I really like what they have done - a great game! ********** I really enjoy the game overall and have worked through most of the free games, including the weekly freebies. However, some of the larger, advanced puzzles can be VERY difficult and frustrating. Sometimes, I may stare at a puzzle for an hour and not see any options from the clues given - that gets frustrating (I am currently over 10 hours on one puzzle alone). I don’t see a “hint” option, which I strongly suggest adding, so I can start to see clues to look for. You provide a “solve” option, but that doesn’t help me learn clues. If a hint option was available, I would be much more likely to buy the other games. As is, I probably won’t.
Developer Response ,
Thank you for your feedback. Adding a "Hint" option is something we are looking at right now and hopefully we will add it as a standard feature to all our apps in the future.
Great puzzle game, enhancement suggestion
This game has brought me many hours of head-scratching enjoyment. The images are very entertaining, and I enjoy the variety.
One minor issue for me is sometimes when I pinch and zoom, I accidentally change a cell I did not intend to change. Finding my mistake is very difficult. I think I have some color blindness because the red color used to show errors is hard to discern, especially on the larger puzzles, and especially for the cells marked with an ‘x’. Maybe a feature that temporarily blurs out the correct cells and the unmarked cells, leaving only the cells with errors, or temporarily enlarges incorrect cells is an alternative.
When I do a very large puzzle, and I think it is complete with no errors, I realize there are one or two cells I still need to mark. However, even on an iPad using the zoom feature, it is hard to find the unmarked cell. A “show me empty areas feature would be very helpful, maybe similar to showing cells with errors.
Developer Response ,
Thank you for your feedback. Although not perfect, the new "Assistant" feature should help you with both issues you describe. In the case of accidentally changing a cell the Assistant will tell you if there is an error and will enable you to fix it automatically. Also, in the case you almost completed a puzzle and can't find the next empty cell, the Assistant will move the grid and show a frame around the area where you can make the next step. We hope this helps.
Simple, but great
Whenever I want to play a game but I’m not in the mood to play something more involved, Fill-a-Pix is the perfect choice. With simple rules, a spartan but functional interface, and tons upon tons of downloadable (IAP) levels spanning everything from very small puzzles to massive iPad-only huge ones, very easy to impossibly hard, and across a wide range of topics, there’s enough here to keep me busy for years.
And years is how long I’ve been playing Fill-a-pix, in fact. I’m grateful that the developer continues to add new level packs even after all this time. The developer’s other number puzzle games are also well worth trying, though I keep coming back to Fill-a-pix time and time again.
Update: Still playing Fill-A-Pix regularly, all these years later. Nikoli, you really know how to deliver a number puzzle game that is simple yet engaging.
