Race your friends live on the same sudoku, or battle on one board. Freeze, fog and steal your way to the win. And a new daily challenge every day. Sudoku Knockout is sudoku you play against your friends, live. PLAY ONLINE • Race: everyone solves the same puzzle on their own board. You see each other's progress, never the numbers. First to finish wins. • Blitz: 3 minutes, a point for every right cell. • Battle: one shared board. Every right cell you fill is yours, and golden cells score triple. • Knockout: 3 to 6 players. The last to reach each checkpoint is out. • Power-ups: freeze, fog, shield and steal. • Invite friends with a code or a link, or fill the seats with bots at three levels. • Set the room's rules: mistake limit, hints, notes, power-ups, or no warnings at all. CHALLENGE YOUR FRIENDS • Beat my time: send a friend your solve and they race your ghost. • Share a result, and anyone who opens the link can race it. • See your record against each friend. DAILY CHALLENGE • A new puzzle every day, the same for everyone, with the same rules. • Keep your streak going, compare times with your friends, or race a friend's daily. PLAY ON YOUR OWN • 6,000 puzzles over six levels, from Easy to Extreme, each solvable by logic alone, with no guessing. • Hints that show why: the cell, the digit and the reasoning behind it. • Notes, highlights and an optional mistake limit. • Statistics, best times and streaks. • Solo puzzles, the daily challenge and rooms with bots work offline. FREE, WITH NO ADS No ads, no purchases, no tracking. Start playing straight away with no account; add your email to keep your progress on every device. In English and Turkish.
