DAILY SUDOKU
One grid a day keeps the boredom away.
Free Online Sudoku, Reinvented
Daily Sudoku is a free browser sudoku game that turns the classic logic puzzle into something you'll come back to every single day. Solve the daily challenge — the same puzzle for every player worldwide — to build your streak. Earn points for every correct move, completed row, column and 3×3 box, then spend them on powers like Time Freeze, Guardian Shield and Auto Notes. But be careful: you only get 3 hearts per game.
Play Sudoku With Friends
Sudoku doesn't have to be a solo hobby. Create a multiplayer room, send the invite link, and solve the same grid together in real time — perfect for coffee breaks, long calls, or beating an Expert puzzle as a duo.
How to Play Sudoku
Fill the 9×9 grid so every row, every column and every 3×3 box contains the digits 1 through 9 exactly once. Use pen notes to mark candidates in tough spots, watch the remaining-count under each number, and let completed lines fuel your power meter.
