How to Play Calcudoku

🎯 Goal

Fill the grid so every row and every column contains each number exactly once — AND every outlined cage satisfies its arithmetic target.

🔢 The Cages

Each outlined region has a label like 12× or 7+ or 3.

  • 12× — the numbers in this cage must multiply to 12
  • 7+ — the numbers must add up to 7
  • 3− — the two numbers differ by 3 (larger minus smaller)
  • 2÷ — the two numbers divide to give 2 (larger ÷ smaller)
  • 5 (no operator) — the single cell must contain 5

✏️ Filling the Grid

  • Tap a cell to select it, then tap a number on the pad (or use keyboard).
  • Cells with errors flash red — fix them before solving.
  • Single-cell cages are pre-filled as givens — you can't change them.
  • 💡 Hint reveals one correct cell.

⚡ Grid Sizes

4×4 uses digits 1–4. 6×6 uses 1–6. 9×9 uses 1–9. Larger grids = longer session, higher score!

The grid is divided into cages, and each cage displays a target number and an arithmetic operation — the numbers in that cage must produce the target when the operation is applied.

What makes Calcudoku distinctly different from Sudoku is that operations include addition, subtraction, multiplication, and division. A cage showing
