About Numbly — Daily Sudoku
Numbly is Wordlio's daily sudoku challenge. A fresh puzzle is released every day at midnight, and every player on the platform solves exactly the same grid. Complete it with fewer mistakes to score higher on the leaderboard. Your result is shared across Wordlio's daily points system — the same streak and ranking infrastructure used by Wordly, Quizly, and Speedly.
Sudoku is a constraint-satisfaction puzzle, not a maths problem — no arithmetic is involved. The nine digits are used because they're nine distinct, recognisable symbols. Every valid puzzle has exactly one solution that can be reached through pure logical deduction. Beginners should look for rows, columns, or boxes with eight numbers already filled — the missing digit must go in the single empty cell. As skill increases, candidate-elimination techniques and pencil marks become essential for harder grids.
How Scoring Works
- Complete the puzzle = earn points toward today's Wordlio leaderboard
- Fewer mistakes = higher position on the daily ranks
- Use the Hint button sparingly — hints count as a mistake
- Three mistakes ends the game; the puzzle resets tomorrow
Frequently Asked Questions
Is it the same puzzle for everyone?
Yes — the puzzle is date-seeded. Every Wordlio player worldwide sees the same sudoku grid on a given day, making the leaderboard a true daily competition.
Can I continue where I left off?
Yes — your progress is saved in your browser automatically. If you close the tab and return later today, your board state, timer, and mistakes are all restored.
What difficulty is the daily puzzle?
Numbly uses a medium difficulty setting — 45 cells are removed from the solved grid. It's challenging enough to take most players several minutes, but completable without advanced techniques.
