Scoring System & Techniques - SudokuWorldTournament

Our Unique Scoring Philosophy

Unlike most Sudoku apps that only measure completion time, SudokuWorldTournament uses an advanced scoring system that recognises and rewards the specific solving techniques you use. This creates a fairer, more skill-based competition.

                Key Principle: Harder techniques earn more points. A player who solves using X-Wing and Swordfish patterns earns more than someone who only uses basic singles, even if they take the same time.
            

Technique Recognition

Our engine automatically detects which solving technique you used for each move. This happens in real-time as you play, with no manual input required.

10 points per cell solved

15 points per cell solved

Time Bonus

Speed still matters! You earn bonus points based on how quickly you complete the puzzle:

Time Bonus Calculation:

Under par time: +50% bonus to technique points
At par time: No bonus or penalty
Over par time: Gradual reduction (max -30%)

Anti-Guessing System

Random guessing is penalised to ensure fair competition:

                First error: Warning only
Second error: -10% score penalty
Third+ errors: -20% cumulative penalty
Rapid incorrect entries: Flagged as potential guessing

            

Puzzle Generation

Our puzzles are generated using a reverse-engineering approach:

                Start with a solved grid
Remove numbers while ensuring unique solution
Verify solvability using only logical techniques (no guessing required)
Rate difficulty based on techniques needed
Assign point values based on technique complexity
