Flash player support

Due to deprecation of Flash at the end of 2020 we are converting all our games to HTML5 which is supported by all popular browsers. We are planning to complete this process before the end of 2019. In the meantime, in case you have problems enabling Flash on your browser please see these instructions

Fill-a-Pix tips


  • Start with the 0's and 9's inside the grid, 6's on the edges and 4's in the corners.
  • Analyze all clues one by one. There is always another step somewhere!
  • Every new square you paint might become a useful clue later on.
  • Never guess! Paint squares only if you are sure they must be filled and mark squares with an "X" only if you are sure they must be empty.

Note: There is only one unique solution for each puzzle.

When solving on paper

  • Use a soft erasable pencil and a high quality eraser.
  • Shade squares lightly so numbers remain visible after the squares are painted.

When playing on a computer

  • Use Preferences options in toolbar for a better personal playing experience.
  • Use Smart-fill Curser to speed up the game. Move cursor with mouse or arrow keys and paint squares with the spacebar or by double clicking cursor edge with the mouse.
