How to Play:

1. Fill each cell with a number so that no number repeats in any row or column (like Sudoku).
2. Each outlined group must use the math operation (+ − × ÷) to reach the target sum or result.
3. For addition groups: add all numbers in the group to match the target.
4. For subtraction: the largest number minus the smallest equals the target.
5. For multiplication: multiply all numbers together to match the target.
6. For division: the largest number divided by the smallest equals the target.
7. Numbers are limited by grid size (2×2 grid uses 1–2, 4×4 uses 1–4, etc.).
8. Work through the clues step by step.
9. Use logic elimination to determine valid placements.
