How does the matchmaking and rank system work in Rocket League?

How does matchmaking in Rocket League work?

Matchmaking pairs players with others around the same skill level. You can do the following to ensure a good matchmaking experience: 

• Play with friends
• Use the Party Up feature to continue playing with players from your previous match

If you are playing with a party, Party Skill uses a Weighted Average instead of only using the highest-ranked player at the party. For more info, refer to: Party Skill and Matchmaking.

How many games does it take to rank up?

There is no fixed number of games that you need to rank up. Ranking up depends not only on wins and losses, but also on the difficulty of the matches. 

Why was my Rank affected after my teammate left?

A loss will be counted regardless of the context. We take unsportsmanlike conduct very seriously and are constantly striving to improve the Matchmaking system. 

We understand that leaving early is not fair to teammates. The player who leaves will receive a Matchmaking Ban. The first player on a team to leave a match early will have a more substantial MMR loss.
