How Does Skill-Based Matchmaking Work? A Deep Dive

Skill-based matchmaking (SBMM) works by analyzing a player’s performance metrics to estimate their skill level and then using this estimation to place them in matches with other players of comparable skill. The fundamental goal is to create balanced and competitive matches, ensuring that no single player or team consistently dominates due to a significant skill disparity. Modern SBMM systems often employ sophisticated algorithms that weigh a variety of factors to achieve this balance.

Understanding the Mechanics of Skill-Based Matchmaking

The implementation of SBMM varies from game to game, but the underlying principles remain consistent. Here’s a breakdown of the key components:

1. Data Collection and Skill Assessment

The first step involves collecting data on player performance. This data can include a wide array of metrics such as:

• Kills and Deaths (K/D Ratio): A basic but often heavily weighted indicator of performance.
• Win/Loss Ratio: Reflects a player’s ability to contribute to winning games.
• Accuracy: Measures how effectively a player lands shots.
• Damage Dealt: Quantifies a player’s contribution to combat.
• Objective Performance: Includes actions like capturing points, planting bombs, or assisting teammates.
• Match Completion Rate: A measure of consistency in finishing matches.
• Ranked Play Statistics: Performance in competitive modes, which often have a more structured skill rating system.

This data is then fed into an algorithm, which calculates a player’s skill rating or matchmaking rating (MMR). This rating serves as the basis for matchmaking. The specific algorithm used is a closely guarded secret by most game developers to prevent players from manipulating the system.

2. Matchmaking Algorithms

Once players have a skill rating, the matchmaking algorithm springs into action. The process typically involves:

• Queueing: Players enter a queue, indicating their desire to join a match.
• Searching: The algorithm searches for other players in the queue with similar skill ratings.
• Balancing: The system attempts to create balanced teams, ensuring that the overall skill level of each team is roughly equal. This may involve slight adjustments to team compositions to compensate for variations in individual skill.
• Prioritization: While skill is the primary factor, other considerations may come into play, such as network latency (ping), geographical proximity (to minimize lag), and player preferences (e.g., preferred game modes or maps).

The algorithm constantly refines its search based on the waiting time. If a suitable match isn’t found quickly, the system may broaden its skill range to include players of slightly higher or lower skill levels to reduce wait times.

3. Adaptive Learning and Continuous Adjustment

A well-designed SBMM system is not static. It continuously learns and adapts based on ongoing player performance. As players improve or decline in skill, their rating is updated, and the matchmaking system adjusts accordingly. This ensures that matches remain competitive and fair over time. This concept closely aligns with the research and expertise shared at GamesLearningSociety.org, emphasizing the importance of adapting systems to enhance player learning and engagement.

Why Developers Use Skill-Based Matchmaking

Game developers implement SBMM for several key reasons:

• Improved Player Retention: By creating fairer and more enjoyable matches, SBMM can reduce frustration and encourage players to keep playing.
• Enhanced Competitive Integrity: In ranked modes, SBMM ensures that players are competing against others of similar skill, maintaining the integrity of the ranking system.
• Protection for New Players: SBMM prevents new players from being repeatedly stomped by experienced players, which can be demoralizing and discourage them from continuing the game.
• Fairer Progression: SBMM helps players progress more steadily, as they are consistently challenged but not overwhelmed.

Drawbacks and Controversies

Despite its benefits, SBMM is not without its drawbacks, which often spark heated debates within gaming communities.

• Increased Sweat Factor: Some players find SBMM overly competitive, as they are constantly matched against opponents of similar skill, leading to intense and stressful gameplay. This often removes the element of casual fun.
• Longer Queue Times: Finding matches with evenly matched players can sometimes lead to longer wait times, especially in less popular game modes or regions.
• Smurfing: To circumvent SBMM, some players create new accounts (smurfs) to play against less skilled opponents. This disrupts the system and creates unfair matches for others.
• Stricter Performance Expectations: Players often feel pressured to perform well in every match, as any dip in performance can negatively impact their skill rating.
• Loss of Variety: Some argue that SBMM reduces the variety of matches, as players are less likely to encounter opponents with drastically different playstyles or skill levels.

FAQs About Skill-Based Matchmaking

Here are some frequently asked questions about skill-based matchmaking to provide a deeper understanding of this complex topic:

1. Does SBMM guarantee perfectly balanced matches?

No. While SBMM aims to create balanced matches, it cannot account for all variables, such as player mood, fatigue, or temporary fluctuations in skill.

2. How does SBMM handle party play (playing with friends)?

SBMM typically uses the highest skill rating within the party to determine the matchmaking bracket. Some systems might average the skill ratings, but this is less common.

3. Can I improve my SBMM rating by playing against bots?

Generally, no. SBMM systems usually exclude matches against bots from their calculations, as they are not representative of real player skill.

4. Does SBMM impact casual game modes?

Yes. SBMM is often applied to both ranked and casual game modes, although its influence may be less pronounced in casual modes.

5. How can I tell if a game uses SBMM?

Developers rarely disclose the specifics of their SBMM systems. However, signs of SBMM include consistently challenging matches, noticeable performance-based matchmaking adjustments, and detailed player statistics.

6. Does a VPN really help me avoid SBMM?

While a VPN can theoretically influence matchmaking by changing your perceived location, its effectiveness in completely avoiding SBMM is debatable and varies from game to game. Some games have measures in place to detect and counteract VPN usage. As the original article stated, “Using a VPN (Virtual Private Network) won’t magically get rid of SBMM. However, you can use a VPN to make SBMM work to your advantage.”

7. Is SBMM the same across all games?

No. The specific algorithms, metrics, and implementation details of SBMM vary significantly from game to game.

8. How does SBMM account for different roles or classes in a game?

Some SBMM systems consider the role or class a player is playing and adjust matchmaking accordingly. For example, a support player might be judged on different metrics than a damage dealer.

9. What happens to my SBMM rating if I take a long break from a game?

Many SBMM systems have a decay mechanism, where your skill rating gradually decreases after a period of inactivity. This allows the system to recalibrate your rating based on your current skill level when you return.

10. Does SBMM consider my ping or connection quality?

Yes, most modern SBMM systems prioritize players with good connection quality and low ping to ensure a smooth and responsive gameplay experience.

11. How do I report suspected SBMM manipulation (e.g., smurfing)?

Most games have reporting mechanisms for suspected cheating or abuse, including smurfing. Use the in-game reporting tools or contact the game’s support team.

12. Why do my Fortnite lobbies feel so sweaty?

As the original article stated, “If you camp to A Victory Royale a lot, the game is going to put you in harder lobbies. The game is counting your skill by your placement and not your kills. If you don’t camp too much it could be because Epic Games decided to reduce skill based matchmaking.”

13. Is SBMM used in all game modes of Fortnite?

Skill-Based Matchmaking works in Solos, Duos, and Trios where players matchmake with other players based on their skill level.

14. How can I identify bots in Fortnite?

Check the player’s name. Bots very often have names that don’t seem like the name of a real player.

15. Does Call of Duty have SBMM?

Yes, Call of Duty implements skill-based matchmaking. Playing Ranked Play matches grants Skill Rating (SR), which is used to determine where players fall in one of the eight Skill Divisions.

Conclusion

Skill-based matchmaking is a complex and evolving technology designed to create fairer and more engaging online gaming experiences. While it has its benefits, such as improved player retention and enhanced competitive integrity, it also faces criticisms related to increased competitiveness and longer queue times. Understanding how SBMM works and its potential impact on your gaming experience can help you better appreciate its role in modern multiplayer games. The principles of SBMM and its impact on player experience can also be explored further through resources such as those found at the Games Learning Society.
