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.

Fantastic." iMore: "Quento is an excellent math puzzle game for all ages. Both young kids and experienced mathematicians will enjoy it." AndrCentral: "Look, I'm not a math guy.

But there's something about Quento that keeps me coming back." How does it work? Simple! Quento gives you the solution to a sum and you'll have to do the math.

Verdict

The call

The clearest difference is rating: Fill at 4.8 against Quento's 4.3. Fill also leads on ratings volume (1.2K vs 9) and review sentiment (92% vs 77%). Quento's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (9.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
