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

Cross-a-Pix tips


  • In SingleClue puzzles start with the very small and very large clues.
  • In DualClue puzzles start with rows and columns in which the first clues are very small or very large.
  • In DualClue puzzles continue with rows and columns in which the second clues are 1 or 2 or where the two clues are identical.
  • Scan all rows and columns one by one. There is always another step somewhere!
  • Every new region you fill might become a useful clue for the next step.
  • Never guess! Paint regions 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.
  • Mark completed rows and columns by checking-off the relevant clues.

When playing on a computer

  • Use Preferences options in toolbar for a better personal playing experience.
  • Use the ruler-tip counters to show the number of filled, blanked or empty squares, as well as the number of blocks in the case of DualClue Cross-a-Pix.
