Solving tips

  1. 1

    One gap first

    A cell in an equation with only one empty spot can be calculated directly.

  2. 2

    Use the bank

    Each number is used once. If only one number fits a cell, it goes there and is gone for every other cell.

  3. 3

    Crossings are the key

    A number where two equations cross must work both across and down.
