Link pairs of identical numbers so that each number represents the number of cells on the link, including the cells with the numbers. Cells containing 1 represent paths that are 1-cell long. Paths must follow horizontal or vertical directions and are not allowed to cross or overlap other paths.

(Rules and example from WPC 2017 IB)

Rule variations[edit]

  • Sum Numberlink from WPC 2016/Round 14 was a Number Net puzzle with an additional constraint of a path not occupying 2x2 cells. As the name suggests this is probably sought to be a variant of Arukone but is much closer to Number Net in terms of the ruleset.

History of the puzzle[edit]

According to Conceptis Ltd, the puzzle was invented by one editor of the Byakuya Shobo publishing company. [1] When did this happen is uncertain, but probably in the late 1990s on お絵かきパズルランド (Oekaki Puzzle Land) magazine, first published in 1995.

Most commonly this puzzle is known as Link-a-Pix (a name by Conceptis), but the name of this article is based on the original name given by Byakuya Shobo, ナンバーネットロジック (Number Net Logic).
