Daily Sudoku (FreePuzzles)

Rate it

A dated 9x9 sudoku for everyone, with three mistakes allowed.

on freepuzzles.net

Daily Sudoku for October 18, 2026, in play at desktop size: a 7 and a 5 entered in row four, a cell selected, timer at 00:08, errors 0 of 3, rules in a panel beside the grid

Daily Sudoku on FreePuzzles.net is a free classic sudoku that changes every day at midnight UTC. Every player gets the same dated 9x9 grid, solves it against a timer with up to three mistakes, and can share the result.

About Daily Sudoku (FreePuzzles)

FreePuzzles.net is a free puzzle site from FlameAI Studio with sliding puzzles, memory games, 2048 and word searches, and a Daily section where each of several games has one puzzle a day shared by all players. Daily Sudoku is the classic 9x9 grid: fill every row, column and 3x3 box with the digits 1 to 9 exactly once.

The day's puzzle is headed with its date and a note that everyone plays the same puzzle today. You click a cell and enter a number. A wrong number counts as an error, and three are allowed before the game ends, so guessing is risky. A timer runs above the grid, and a Notes mode, toggled with the N key or the Notes button, lets you pencil in candidates.

When you finish, you can share your time and result with friends who played the same grid. A new puzzle goes up every day at midnight UTC. There is no account, nothing to install and no advertising on the page; it plays in any browser, and the grid fits a phone screen as well as a desktop one.

How to play Daily Sudoku (FreePuzzles)

  1. Open Daily Sudoku and check the date at the top.
  2. Click an empty cell to select it.
  3. Type a digit from 1 to 9; each row, column and 3x3 box must hold every digit once.
  4. Press N or the Notes button to pencil in candidates instead of answers.
  5. Finish the grid with fewer than three mistakes and share your time.

Tips

  • Use Notes for any cell you are not sure of; with only three mistakes allowed, a guess can end the game.
  • Start with the rows, columns and boxes that already hold the most digits.
  • Look for a digit that can go in only one cell of a box before working cell by cell.
