One Ranking for Every Player

Introducing the OpenScor Ranking System

Vision: One Ranking One Community

Imagine a world where every game you play — from a friendly challenge at your local club to a competitive final — contributes to a single, accurate, and meaningful ranking. A ranking that shows you where you stand not just in your local community, but in your region, and even the world.

This is the vision of OpenScor. We are building a truly unified global ranking system from the ground up, starting with the heart of competition: the local club and community.

The Problem: A Fragmented and Inaccurate Landscape

Isolated Community Rankings: Most local rankings are simple win/loss systems. They are easily gamed, often inaccurate, and only reflect who you've played within a small circle.

Low Player Engagement: Without a true sense of progress or a clear "what's next," player motivation can fade.

Barriers to Competition: Tournaments are expensive, time-consuming, and can be intimidating for many players.

Multiple, Confusing Rankings: Players often juggle different rankings that don't communicate with each other.

The Solution: The Unified Ranking System

What is the Unified Ranking?

The Unified Ranking is a sophisticated system that uses advanced algorithms to calculate accurate player ratings. It supports multiple calculation methods including ELO, Glicko, and TrueSkill, with customizable parameters to suit different competitive environments.

Starting Score:Configurable (default: 300)
K-Factor Base:Adjustable (default: 32)
Rating Spread:Customizable
Calculation:Multiple Methods
Score Aggregation:Games/Matches/Points
Custom Rules:Fully Configurable

The Science Behind the Unified Ranking

Advanced Ranking Algorithm

Our ranking system uses a sophisticated algorithm that considers multiple factors for accurate rating calculations:

1. Expected Score Calculation

For each match, we calculate the expected outcome based on rating differences:

Expected Score = 1 / (1 + 10^(rating_diff / rating_spread))

2. Dynamic K-Factor

The K-factor adjusts based on multiple factors:

  • Match count (decays with experience)
  • Rating difference between players
  • Match importance (tournament vs. friendly)
  • Score difference (dominant wins count more)

3. Custom Rules Engine

The system supports various rule types:

  • Match Importance (tournament weighting)
  • Player History (experience-based adjustments)
  • Rating Difference (upset bonuses)
  • Custom Rules (domain-specific logic)
