Sudoku in one sentence
Fill the 9×9 grid so every row, every column, and every 3×3 box contains the digits 1–9 exactly once. Some cells are filled in for you as clues.
Try it — a mini 4×4
Try it: fill the blanks so every row, column, and 2×2 box contains 1–4.
How the race works
- Everyone in a room gets the identical board.
- A synced 3-2-1-GO! starts the clock for all players at once.
- The first correct submission triggers a 30-second countdown — everyone else races to finish and grab 2nd, 3rd, etc.
- 📊 If time runs out, rankings use completion percentage.
