Fill-a-pix is coded black and white image. The form does not unravel looks like a table with cells that contain the numbers from 0 to 9. The numbers show how many cells around, including direct cell itself, is painted. Some numbers are hidden (empty cell) to complicate the solution. This puzzle is also known as "Mosaic". His rules and is slightly reminiscent of a puzzle game "Minesweeper". By default, cells are shaded in gray. Left button (or tap on touch screens) put a black cell, right - white. Key Appointments can be reversed by clicking on the button with the black / white triangles. For convenience, the number of cells crucial change color depending on the state: Red - the number of painted squares around the more acceptable, or not enough cells available to paint, to reach the specified number. Blue - the number of painted squares around the same as the number in the cell, but there are free cells, which can be noted in white. Green - painted all the cells around the cell and the number coincides with the number of cells painted black color. Brown - all empty cells around can only be black. Most of the puzzles, especially small, compiling a program is trying to remove as many numbers as possible to tackle the most difficult and was left as little as possible solutions paths, and ideally - all alone.
