Matchmaking is the process an online game uses to select which players or teams play against or with each other. A matchmaker takes a queue of waiting players and forms matches according to rules such as skill rating, region, party size and game mode.
Why it matters
Good matchmaking decides whether games feel fair and responsive. It balances competing goals: close skill levels, short queue times and low latency. If the player pool is small, such as at off-peak hours or in a niche region, the system must relax a criterion, so you may wait longer, face wider skill gaps or connect to a distant game server.
Example
A simple matchmaker might work like this:
- Place players in a queue with a skill rating, such as 1500.
- Start with a rating window of plus or minus 50.
- Widen the window by 25 every 10 seconds of waiting.
- When ten players fit a window and share a region, create the match and assign a server.
Common misconceptions
- Matchmaking is purely random. It is typically rule-based and tuned by the developer.
- A rating is a measure of overall player worth. It is only an estimate used for pairing.
- Ping is the only network factor; jitter and packet loss also matter.
