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

Link-a-Pix tips


  • Start with the short paths of 1, 2 and 3, and then move up to longer ones.
  • Don’t forget the squares at each end when counting path lengths.
  • Paint partial paths whenever possible. This will usually help with neighboring paths as well.
  • Every new path you paint might help in a next step.
  • Determine which clues pair with which. Using odd/even parity can help with this process.
  • Never guess! Paint each path only after you are sure it is unique.

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

When solving on paper

  • Use a soft erasable pencil and a high quality eraser.
  • Draw paths as thin lines and paint the squares later.
  • Lightly draw temporary paths to see which pairs of clues are blocked from others.
  • Experienced solvers can paint with markers for outstanding results.

When playing on a computer

  • Use Preferences options in toolbar for a better personal playing experience.
  • Paths can be started from both ends, and then joined together later on.
  • Path fragments can also be painted by starting from any empty square.
  • Any path can be deleted by double-clicking the mouse or using the Delete key.
