As the leader of the Machine Learning team at Hike Limited, I spearheaded the development of an innovative AI-driven matchmaking system for Rush, Hike’s real-money gaming network. Our goal was to create a fair, engaging, and highly personalized gaming experience by automatically matching players based on their skill levels, gaming behavior, and overall user experience.

Project Overview #

The Rush ML project aimed to develop a sophisticated matchmaking algorithm that could quickly and accurately pair players in competitive gaming scenarios. This system needed to balance multiple factors including player skill, game preferences, and historical performance to ensure fair and enjoyable matches for all participants.

Technical Approach #

Core Technologies #

  • Python for algorithm development and data processing
  • TensorFlow for building and training machine learning models
  • BigQuery for large-scale data storage and analysis
  • Airflow for workflow management and scheduling
  • Custom-built ranking algorithms inspired by chess ELO and TrueSkill systems

Key Components #

  1. Player Skill Evaluation: Developed a multi-faceted rating system that considers various game-specific skills and overall player performance.

  2. Behavioral Analysis: Created models to analyze player behavior, including play style, game preferences, and interaction patterns.

  3. Real-time Matchmaking Engine: Implemented a high-performance system capable of making instant matchmaking decisions.

  4. Fairness Assurance System: Developed algorithms to ensure balanced matches and detect potential unfair advantages.

  5. Adaptive Learning: Implemented a system that continuously learns and adapts based on match outcomes and player feedback.

Challenges and Solutions #

  1. Challenge: Balancing match quality with waiting times. Solution: Developed a dynamic algorithm that adjusts matching criteria based on queue times and player pool size.

  2. Challenge: Ensuring fairness in a diverse player ecosystem. Solution: Implemented a multi-dimensional ranking system that considers various skills and factors beyond just win/loss ratios.

  3. Challenge: Handling new player onboarding effectively. Solution: Created a rapid assessment system for new players, using initial games to quickly gauge skill levels and adjust matchmaking accordingly.

Implementation Process #

  1. Data Analysis: Utilized BigQuery to analyze vast amounts of historical gaming data, identifying key factors influencing match quality and player satisfaction.

  2. Algorithm Development: Developed and refined matchmaking algorithms using Python, incorporating machine learning models trained with TensorFlow.

  3. System Integration: Integrated the matchmaking system with Rush’s gaming infrastructure, using Airflow for orchestrating data pipelines and model updates.

  4. Testing and Optimization: Conducted extensive A/B testing to fine-tune the algorithm, comparing various matchmaking strategies and their impacts on player experience.

  5. Monitoring and Iteration: Implemented real-time monitoring of matchmaking quality and player satisfaction, allowing for continuous refinement of the system.

Results and Impact #

  • Achieved a 40% increase in player retention rates.
  • Improved overall match quality ratings by 60%, as reported by players.
  • Reduced average queue times by 30% while maintaining high-quality matches.
  • Detected and prevented unfair matchups, leading to a 50% reduction in reported negative gaming experiences.

Conclusion #

The AI-driven matchmaking system for Hike’s Rush platform represents a significant advancement in online gaming technology. By successfully balancing multiple complex factors in real-time, we created a system that not only enhances player enjoyment but also ensures fairness and competitiveness in a real-money gaming environment.

This project showcases the power of AI in transforming user experiences in the gaming industry. It demonstrates how sophisticated machine learning algorithms can be applied to create more engaging, fair, and personalized gaming ecosystems.

The success of the Rush ML matchmaking system has set a new standard in the online gaming industry, particularly in the real-money gaming sector. As we continue to refine and expand this technology, it remains a cornerstone of Rush’s commitment to providing an unparalleled gaming experience that is both exciting and equitable for all players.
