Sudoku: goal and players
Play Sudoku online on JAWNA at jawna.app. Check the goal and supported player counts before inviting your group. Read the rules even if you know the game: familiar names can have different variants, and your usual house rules may differ from the selected version.
Supported table sizes: 2, 3 or 4 players. Choose a player count in the game settings. In partner variants, check seats and teams first. In individual formats, each player competes for their own result. The in-game How to play screen provides details. Agree on the variant before your first round together.
How to play: rules
- Fill the grid so every row, every column and every 3×3 box has each number from 1 to 9 exactly once.
- Everyone gets the same puzzle at the same moment and plays at once. The first to fill the whole grid wins.
- Tap a square, then a number. Every number is checked straight away: a right one locks in place, a wrong one turns red and costs a heart. Lose all 3 hearts and you are out of the race (you can keep watching).
- Turn on Notes to pencil small possible numbers into a square. Notes are only on your phone. Placing a number clears it from the notes around it.
- Undo takes back notes and wrong numbers. Erase clears a wrong number or the notes in a square.
- You see how far the others are and how many hearts they have, never their numbers.
- Solo has no time limit: the clock counts up. A race ends when its clock runs out (10 to 60 minutes, by level); players still in are ranked by progress, then those who ran out of hearts.
- Six levels, from Beginner to Master. A level is set by the solving tricks its puzzles need. Solo Beginner and Easy puzzles give you 3 hints.
- Every puzzle has exactly one answer and can be solved by logic alone, no guessing.

History & origins
The modern puzzle reached Japan from an American magazine under the name Number Place. Nikoli introduced it to Japanese readers in 1984.
Its long Japanese title was shortened to Sudoku. Nikoli’s later use of symmetrical clue layouts helped establish its recognisable puzzle style.
It then became an international newspaper and digital favourite. Jawna turns that traditionally solitary logic puzzle into a race on the same grid.
