🎯 How do you play a 12×12 Grid?
Whether you print a free printable sudoku 12×12 PDF or play directly on our digital board, the core logic remains intact, but the geometry shifts slightly to accommodate the extra numbers:
- The Numbers 1 to 12: Every row and every column must contain the numbers 1 through 12 exactly once. No repeats are allowed.
- The 3×4 Rectangles: In a standard game, the sub-grids are 3×3 squares. In a printable 12×12 sudoku, the board is divided into 12 rectangular blocks that are 3 cells high and 4 cells wide. Every 3×4 block must also contain the numbers 1 through 12.
- Use Robust Notes: Because you are tracking 12 variables across 144 cells, mental memory will fail you. You absolutely must draft candidates heavily in the margins of your paper.
