Rule variations[edit]

  • Contrary to its name, there is no need for the puzzle to have exactly four snails.
  • Word Hitori Snail from WPC 2017/Round 23: Furthermore, cells without a letter cannot share an edge. Although this variation is called Hitori, there were no rules about the connectivity.

History of the puzzle[edit]
