How do I play?

Your goal is to fill the entire grid with the numbers 1 to 9.

🔢 Follow the Sudoku Rules

Each row, column, and 3×3 block must contain the numbers 1 to 9 without repeating.

➕ Complete the Cages

The numbers inside each cage must add up to the small number shown in its top-left corner. The same number cannot appear more than once in a cage.

🧠 Use the 45 Rule

The numbers in every row, column, and 3×3 block always add up to 45. You can use this to work out missing numbers as you solve.

💡 Need Some Help?

Start with the easy difficulty while you get used to the rules. Use notes to keep track of possible numbers or a hint if you're unsure how to continue.
