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.
