  • No number repeated in a row or column.
  • Bold irregularly-shaped boxes represent blocks.
  • Number and operation on a block’s top-left corner represents the entire block.
  • 4 operations
    • \(+\) : Numbers of the block should add up to the representative number.
    • \(-\) : Absolute difference of two numbers in the block should equal the representative.
    • \(\times\) : Multiplying the numbers should equal the representative.
    • \(\div\) : Dividing the larger number by the smaller number should equal the representative.
  • Use the representative if there’s no operation.
