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, the list is "ONE TWO THREE")
- 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
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.
