Some kids compete against other players. Aryan competes against yesterday's version of himself. He'd played his 6×6 personal best of 4:18 four days in a row. Kidoku Live gave him a real leaderboard benchmark to chase.

6×6 Grand Prix · Global rank: 14th this session
Aryan doesn't celebrate when he wins at board games. He calculates whether he could have won faster.
He'd discovered sudoku last year and immediately started timing himself. 4×4 mastered in two weeks. 6×6 took a month to get below five minutes. He kept a note in his phone: every best time, every date.
The problem: he had no reference point. He didn't know if 4:18 was fast for a 6×6. Was he good? Was that average? Was there a ceiling?
Kidoku Live answered all three questions. In his first Grand Prix session, finishing in 4:18 put him 9th out of 14 players. Not elite. But the player who finished 1st did it in 3:41. He now knew where the ceiling was.
He played seven sessions that day. By his fourth session he'd broken 4:09. By his seventh, 3:58 — a personal best.
The improvement was real, measurable, and visible. There was no ambiguity. He knows where he was. He knows where he is. He can see the distance to where he wants to be.
That's the only game Aryan has ever wanted to play.
Structure, timing, and real competition — the three things deliberate practice needs.
Millisecond precision. Your finish time is recorded on the live leaderboard alongside every other player. Improvement is always visible — to you and everyone else in the session.
Grand Prix is a multi-round series. Your position improves or drops across rounds. Consistent fast solves compound into a high overall ranking — patience and speed are both rewarded.
The Hall of Fame shows the fastest times ever recorded per grid size. 3:41 for 6×6. 7:09 for 9×9. Now he has a concrete target. Now practice has direction.
As soon as you finish, your place is locked in. 1st, 7th, 14th — no fluff, no stickers, no vague encouragement. The leaderboard tells the exact truth.
Shaving 9 seconds off per game is invisible in any single session. Across a week, it's the difference between 9th and 2nd place. The game rewards consistent practice, not just talent bursts.
One game, fastest time wins, no series commitment. Use Quick Match as training rounds — warm up your pattern recognition before a serious Grand Prix attempt.

Not faster at a video game. Faster at real constraint reasoning. Faster than real players. Faster than yourself yesterday.
Everything you need to know about Kidoku Live for this use case.
The Hall of Fame is the global all-time leaderboard showing the fastest times ever recorded for each grid size. Any player who submits a Hall of Fame attempt is added to the global ranking. It is permanent, public, and updated in real time. Getting onto the Hall of Fame for a 9×9 grid is a genuine competitive achievement.
Daily Grand Prix practice is the most effective method. Playing the same grid size repeatedly develops consistent scan patterns and placement speed. Most children who practice daily show a 30–50% time reduction within two to three weeks. Practice in Quick Match mode before attempting Hall of Fame submissions.
The Hall of Fame tracks best-ever times for each grid size globally. The current record holders are visible on the leaderboard at kidoku.app/live. These are real submitted times from real players — there are no demonstration records or bot times on the board.
Yes. Any player who completes a Daily Grand Prix receives a global rank for that session. Top performers are visible on the Grand Prix history. Hall of Fame submissions place you permanently in the global record on your chosen grid size. Children from small towns have achieved global top-20 rankings through consistent daily practice.
The Grand Prix runs daily at 4 PM. Every day is a new puzzle, a new leaderboard, a fresh chance to improve your ranking. Missing a day means no Grand Prix entry for that date — there are no retroactive entries. This daily rhythm is what creates the habit-forming quality of competitive practice.
Open the Grand Prix. Finish fast. See exactly where you stand. The next session is already better.
