Sudoku was always a game you played alone. Not anymore.
Dueloku drops you onto the same puzzle as a live opponent and you race —
every correct number is a point and fills the grid for both of you. The
first one to crack it wins. Think chess.com, but for sudoku.
THE TWIST: THE 5-SECOND BLOCK
Guess right, you score. Guess wrong, you're frozen for 5 seconds while your
opponent solves uncontested. Every number becomes a decision: play it safe,
or gamble for the lead? This single rule turns sudoku into a nerve game.
RANKED, WITH REAL STAKES
- A separate ELO rating for every difficulty: Easy, Medium, Hard
- Matchmaking pairs you with players near your skill
- Win and climb. Lose and drop. Your rating is earned, never bought.
THREE WAYS TO PLAY
- Ranked: competitive matches that move your rating
- Friendly: challenge a friend, just for bragging rights
- Practice: solo solving to sharpen up before you queue
BRING YOUR RIVALS
Add friends, challenge them directly, and we'll track your full head-to-head
record — wins, losses, and draws against each one, at every difficulty.
SEE EXACTLY HOW YOU WON (OR LOST)
Every match ends with a breakdown: final scores, rating change, accuracy,
and a flow chart of how the lead swung — including the moment it changed
hands. Learn something from every game.
BUILT FOR QUICK SESSIONS
Most duels run a few minutes. Queue up on your commute, settle a score on
your break, climb a tier before bed.
Sign in with email, Google, or jump straight in as a guest — your progress
carries over if you create an account later.
Make sudoku competitive, social, and genuinely thrilling. One puzzle at a time.
