How Does Ranking and MMR Work in Rocket League

‍1. Understanding the Basics: What is MMR?

MMR, or Matchmaking Rating, is a hidden numerical value representing your Rocket League skill level. Every time you play a competitive match, your MMR changes based on whether you win or lose. This MMR is the foundation of the game’s matchmaking system, ensuring you are paired with players of similar skill levels. Your MMR is not visible to players; it only shows when one reaches the Grand Champion or Supersonic Legend rank. 

This number is important because it influences your rank, but for each game mode, it works separately. For instance, your 1v1 MMR differs from your 3v3 MMR; thus, how well you do in one mode doesn't change your ranking in another.

2. How Ranks are Structured

Rocket League has a tiered ranking system similar to other games, such as Rainbow Six Siege and League of Legends. It has eight main ranks, starting from Bronze and going up to Supersonic Legend.

Each of these, excluding the Supersonic Legend, has three levels—for instance, Gold I, Gold II, and Gold III. Each of these rank levels have four divisional breaks in them. In the case of Gold, it would show Gold I Division I, Gold I Division II, and so on up to IV.

‍

While winning matches increases the MMR to promote the player to the next division or level, losing decreases the player's MMR and might demote them to a division or level lower than their current one.

The exact MMR required to increase and decrease between ranks and divisions slightly differs from time to time, depending on the current season’s player distribution, as the developers frequently change these ranges to maintain a balanced competition.

3. How MMR is Calculated and Adjusted

The MMR system in Rocket League is dynamic and adjusts after every match you play. However, the MMR doesn’t increase or decrease in fixed values. Rather, it can vary depending on several factors.

Opponent’s MMR: Rocket League rewards those players who defeat a higher-ranked opponent than them. So, if you beat a player whose MMR is higher than you, you’d be rewarded more MMR, and they’d lose more MMR. Conversely, losing to a team with an overall lower MMR than your team will result in a more significant MMR loss for you.

‍

Performance in Placement Matches: You must play some placement matches at the beginning of each season. 

These games are crucial for your starting rank of the season, and the MMR that changes from those games will be bigger than in the case of regular matches when your rank starts to converge according to the skill level the algorithm determines.

Playing in Parties: When playing with friends in a party, the game adjusts the MMR calculation to prevent a high-ranked player from boosting lower-ranked teammates. The system heavily weights the MMR of the highest-ranked player in the party, making matches tougher to ensure fairness.

‍

4. Seasonal Resets and Rank Decay

The devs reset your rank at the start of every season, requiring you to play 10 competitive placement matches in every ranked playlist. 

It doesn’t completely erase your MMR but slightly adjusts it to a lower level. In gaming terms, it’s also called a ‘Soft Reset’. Your rank is based on performance from the prior season but isn't the same, allowing for a new competitive experience.

A while back in season 4, Psyonix implemented a ‘Hard reset’, where they reset everyone’s rank to the equivalent of a new account. This created problems for them, and since then, they have resorted to soft resets.

‍

The game also has a system in place to stop "unintentional smurfing." This is when the players get ranked lower than their actual skill when they have not played the game in a while. 

If the game detects that much higher skill in other modes for that player compared to their placement matches, it could raise their starting rank to reflect their actual skill better.

‍

5. Impact of Ranks on Rewards

Rocket League gives special rewards at the end of each competitive season based on your highest rank. These rewards include cosmetic items like banners, wheels, and decals that show your rank. Higher ranks get more valuable rewards, incentivising players to climb the competitive ladder.

However, just reaching a rank doesn’t guarantee the reward of that specific rank. Psyonix has implemented a system where you’d need to play and win 10 additional matches to unlock a reward of that rank. The post-match screen will display a progress bar with the currently unlocked reward.

6. Common Myths About MMR and Ranks

Several myths about MMR and ranks are common among beginner players, so let’s address these in greater detail.

Myth 1: Individual Player Performance Affects MMR

One such myth is that personal performance within individual matches—scoring, assisting, or winning the MVP—was a factor in gaining or losing MMR. In general, players tend to speculate about having a phenomenal game even in defeat, lessening the MMR penalty, or that scoring many goals in a win might award bonus MMR.

However, this is untrue. The Rocket League MMR system enforces teamplay, which means the team has to work together to win the match. The individual goals, assists, saves, and even MVP doesn’t grant you more MMR than your teammates.

It’s understandable for new players, as competitive games such as Valorant and CS:GO reward players more points for their good individual performances. However, in Rocket League, the system is straightforward: win to gain MMR, lose to drop MMR, regardless of how well you performed in that match.

Myth 2: You Can’t Lose Rank After Promotion

Another myth about the Rocket League ranking system is the misconception that players are never demoted once promoted to a new rank. Players assume that crossing into a new milestone-say, from Gold III to Platinum I, is 'safe' in the new rank regardless of subsequent losses.

Yes, it is possible, and demotion happens when your MMR falls below the required mark for any rank or division. 

This means that, even though you just got promoted to Platinum I and then lost some matches, your MMR could decrease enough to bump you back into Gold III. This is because the system is intended to make ranks accurately indicate your current skill level at any given time rather than enabling players to "coast" on old skills​.

Final Thoughts

Knowing these myths and the truths about Rocket League's ranking and MMR system is important for getting better at the game. 

The system is designed to be fair and representative of your actual skill level, rewarding consistent team success rather than solely individual talent and ensuring each playlist offers something different in terms of competitiveness. Knowing the truth behind these common misconceptions will make navigating the levels a lot easier and help you climb up the career ladder.
