How to solve

  • One line per cell: Every cell holds a single diagonal, either / or \.
  • Corner numbers: A number on a corner says how many diagonals touch that corner (0 to 4).
  • No loops: The diagonals can never join up into a closed loop.
  • Unnumbered corners: Corners without a number can touch any number of lines.
