Rule variations[edit]

  • In some puzzle, rotated/reflected images are considered identical.
  • Puzzle asking a triplet among pairs / a pair among triplets is possible.
  • In Find a Pair puzzles from WPC 2016/Round 7, the images were subgraphs of a complete graph with 7 vertices. In one of the puzzles, solvers were asked to find which two graphs were complements, or dual graph, of each other.

History of the puzzle[edit]
