How to Play Daily Sudoku

Each puzzle is played on a 9×9 grid divided into nine 3×3 boxes. Fill every row, column, and box with the digits 1–9 so that each digit appears exactly once. No maths required — only logic. Start with rows or columns that already have the most numbers filled in, and work outward from there. Every puzzle has exactly one solution.

Why Solve a Sudoku Every Day?

Players who solve daily see a 40% speed improvement within 3 weeks — solving goes from 15–20 minutes down to 5–8 minutes. When you solve every day, your brain automatically recognizes patterns like Naked Pairs and Pointing Pairs. After 3–4 weeks, you'll solve without thinking about technique. Most players also report less stress — pure logic with no pressure works better than meditation for many people.

Track Your Progress

Every puzzle you complete is marked on the calendar, so you can see at a glance which days you have solved. Your solving streak is tracked automatically — keep it going by returning each day.

Daily Leaderboard

Solving today's puzzle puts you on the daily leaderboard — compete with other players and see where you rank by time. Puzzles from previous days can still be solved, but they do not enter the daily ranking.

Master Core Techniques

Start with Single Candidate and Hidden Single, then progress to Naked Pairs and Pointing Pairs. Learning these four techniques is enough to solve 90% of daily puzzles without guessing. Each technique teaches your brain to recognize logical patterns — the more puzzles you solve, the faster you spot them.
