What is Brain Age?
Brain Age is a metric that estimates your cognitive performance relative to age-based norms. In SudokuWorldTournament, we calculate your Brain Age based on two key factors: processing speed (how quickly you solve puzzles) and reasoning accuracy (how efficiently you apply logical techniques).
The Science Behind Our Calculation
Our Brain Age algorithm is inspired by research on fluid intelligence and processing speed – two cognitive abilities that are well-measured through logic puzzles like Sudoku.
Processing Speed
Processing speed refers to how quickly you can take in information, make decisions, and execute responses. In Sudoku, this manifests as:
- Time to identify candidate eliminations
- Speed of pattern recognition
- Efficiency of scanning techniques
Fluid Intelligence
Fluid intelligence is the ability to solve novel problems without relying on previously acquired knowledge. Sudoku is an excellent measure because:
- Each puzzle is unique
- Success requires logical deduction, not memorisation
- Advanced techniques require abstract reasoning
How We Calculate Your Brain Age
The Formula Components:
- Base Time Score: Your solving time compared to difficulty-adjusted benchmarks
- Technique Efficiency: Points earned per minute of solving time
- Error Penalty: Adjustments for mistakes and guessing
- Consistency Factor: Performance stability across multiple puzzles
Interpreting Your Results
Brain Age 20-30
Exceptional performance. You're solving at peak cognitive efficiency.
Brain Age 30-40
Excellent performance. Strong processing speed and reasoning.
Brain Age 40-50
Good performance. Room for improvement in speed or technique.
Brain Age 50+
Keep practising! Regular Sudoku can help improve your score.
Improving Your Brain Age
Tips for better performance:
- Learn advanced techniques: Efficient solving earns more points per minute
- Avoid guessing: Errors significantly impact your score
- Practice regularly: Consistency improves processing speed
- Challenge yourself: Harder puzzles provide better cognitive training
Scientific Basis
Our approach is inspired by established cognitive assessment methods, including:
- Processing Speed Index from the Wechsler Adult Intelligence Scale
- Research on fluid intelligence and ageing
- Studies on the cognitive benefits of logic puzzles
