Weekly Sudoku Grand Prix: Rules, Scoring & Leaderboard Guide
Welcome to the Weekly Sudoku Grand Prix on iLoveSudoku. Every week, the system generates a standardized weekly seed using an identical algorithmic generator, allowing players to test their speed and accuracy against the weekly benchmark.
Standardized Seed
The weekly tournament uses the same deterministic seed and scoring rules for every local tournament session.
Division Ranks
Climb from Bronze through Silver, Gold, Diamond, and Grandmaster divisions. High-percentile finishes earn seasonal trophies displayed on your local profile dashboard.
Fair Play & Deductive Integrity
Puzzles are engineered and validated through our DLX solver to ensure exactly one unique solution. In tournament mode, automatic hints are disabled and invalid digit submissions incur time penalties to reward precise calculation.
Tournament Mechanics & Scoring Calculation
The tournament score is calculated using an inverse time decay model combined with accuracy multipliers:
- Base Score (10,000 Points): Every completed round begins with a baseline pool of 10,000 potential points.
- Time Decay: Points decay by a steady rate for each second spent solving. Fast candidate scanning and efficient pencil marking minimize score decay.
- Mistake Penalty: Entering a conflicting digit adds an instant 30-second penalty to your final elapsed time, emphasizing careful verification over hasty guessing.
- Weekly Reset: Tournament brackets cycle every Sunday at 23:59 UTC, refreshing the weekly challenge seed and resetting the local bracket board.
Frequently Asked Questions
Can I pause the tournament timer?

What difficulty is the tournament puzzle?
Tournament puzzles rotate weekly between Medium-Plus and Hard tiers, requiring techniques such as Naked Triples, Pointing Pairs, and Snyder notation to solve without guessing.

You can practice the puzzle multiple times, but only your first completed round is recorded on your weekly personal ranking board.
