From WPC unofficial wiki


Draw a path passing through the centres of all cells horizontally and vertically. All words from the given list must be read along the loop only in a single direction in the given order.

(Example from Japan National Finals 2006[1], the list is "ONE TWO THREE")

Rule variations[edit]

  • In the original puzzle, along the path the letters read ONETWOTHREE.
  • Sutuna Loop from WPC 2017/Round 23: Instead of a path, the objective was to draw a loop, and there were no given order of words.

History of the puzzle[edit]

First appeared on Japan Nationals 2006. Author of the puzzle is unknown. Sutuna is probably the contraction of 数字つなぎ (Suji Tsunagi, lit. "Number Connection"). There were a puzzle named 数字つなぎ (known in English as Number Connection) prior to Sutuna. The naming is most likely to signify that Sutuna is a variant of Number Connection with word puzzle element.
