How the Daily Sudoku Puzzle Works
Everyone gets the same Sudoku for the same date and difficulty. That keeps the daily challenge fair, repeatable, and easy to compare without generating extra indexed archive pages.
Daily Sudoku Difficulty
Easy has more clues and more hints. Medium is balanced. Hard and Expert remove more starting numbers, reduce help, and reward cleaner leaderboard runs.
Daily Sudoku Leaderboard
Signed-in clears save to a separate Daily Sudoku leaderboard, so regular Sudoku scores and daily challenge scores stay clean.
