Abstract: Systems and methods for solving and generating a mathematical puzzle are presented. A puzzle may comprise areas comprising mystery number regions, pair clue regions interposing pairs of mystery value numbers, and a central clue region located centrally to the mystery number region. Solving a puzzle may comprise deterministic search methods coupled with heuristic approaches. Puzzle generation may comprise adding conforming clues until a puzzle has only one possible solution, the clues chosen based on heuristics for adding clues while minimizing incremental change in puzzle difficulty; or reducing the number of solutions/partial solutions to the puzzle.
