How to Play

  • The grid size defines the numbers you can use in a puzzle. If it’s a 3×3, you’ll use numbers from 1 to 3. If it’s a 4×4, from 1 to 4. And so on!
  • Squares outlined by bold lines are called cages. Each cage has a target number and a an associated math operation.
  • Each cage must be filled with numbers that, combined in any order, produce the target number of the cage using the correspondent math operation.
  • Numbers may not be repeated in any row or column, just like Sudoku.
