Sudoku Showdown: Online Duel

Sudoku, but live. Challenge real players to head-to-head Sudoku battles — same puzzle, same clock, one winner. Quick match in seconds or invite a friend with a code. No account needed, just pick a nickname. THREE WAYS TO BATTLE • Race — One shared board, both of you solving at once. Chain correct answers to build a streak: every cell scores more than the last. A wrong number resets your streak and locks you out for 10 seconds. • Duel — Separate hidden boards. You only see your rival's progress. First to finish wins, and every mistake adds +5 seconds. • Turns — Take turns on one board with a 10-second clock. Place a correct number and you keep the turn. Miss, and it's theirs.
