How to play

  1. Fill the grid with 1 to N, once per row and once per column, like a Latin square.
  2. Thick lines mark cages. The digits in a cage must make the number in its corner using the sign shown.
  3. A cage with − or ÷ has two cells; the order doesn't matter.
  4. Digits may repeat inside a cage, as long as they're in different rows and columns.
  5. No digits are given: the cages are the only clues, and every puzzle has one solution.
