Super Sudoku
Classic 9×9 sudoku with flexible input, so you can fill cells the way that suits you and jot notes as you go.
Controls
Click a cell then a number, or pick the number first and place it; use note mode to pencil in candidates.
How to Play
Complete the 9×9 grid so that every row, every column and every 3×3 block contains the numbers 1 to 9 exactly once. Nothing needs to add up; the whole puzzle rests on where each digit is and is not allowed to sit.
Newcomers can get the hang of it quickly by reading our step-by-step guide first. From there, pick whichever input style feels natural and start narrowing down the grid.
Tips & Tricks
- Try both cell-first and number-first entry to see which keeps you quicker.
- Use note mode to hold two or three possibilities in a cell until one is ruled out.
- Finish the digit you are working on across the whole board before switching to another.
Frequently Asked Questions
Can I switch how I enter numbers in Super Sudoku?
Yes. You can select the cell first and then a number, or choose the number first and place it in a cell, whichever you prefer.
What are the pencil notes for?
Notes let you mark the possible digits for a cell without committing, which helps when a square could take more than one value.
