Dota 2 MMR Ranking System Explained
Dota 2's MMR Ranking system is inherently complex and includes various nuances, making it hard for the average gamer to understand it. Over the last decade, while Dota 2 had numerous tweaks to gameplay, heroes, economies, and landscapes, there has also been an equally high number of changes to its matchmaking rating (MMR). New players or players who have not played for a long period of time might struggle to grasp how the current form of Dota 2 MMR works. So here is a comprehensive guide that walks you through the various aspects of the Dota 2 MMR ranking system.
What is Dota 2 MMR and Medals?
Dota 2 matchmaking rating (MMR) is a positive integer that represents a player’s skill level. MMR also helps determine your allies and opponents in various matches, so it is also Dota 2’s matchmaking tool. However, Dota 2 players can only earn and lose MMR points by playing ranked matches and not by playing other game modes.
Based on your MMR level, you will be provided with a specific Dota 2 medal. There are eight Dota 2 medals currently. In the increasing order, they are:
There are five tiers/stars within each medal, with tier five being the highest. As you win and lose ranked matches, your tiers and medals might change.
For example, if you are in the Legend 4 tier on Friday and then win a certain set of matches in the next couple of days, your medal tier will move from Legend 4 to 5. Additionally, if you go on to win more ranked matches than you lose in the coming days, you will move from Legend five to Ancient one.
Barring Immortal, the highest rank in Dota 2, every medal has tiers. In Immortal, you will instead have a ranking placement based on your region, so the player who has the highest MMR in a region will have rank 1.
Dota 2 Medal Distribution Based on MMR
Even though Valve has never revealed the MMR required for achieving a particular medal tier or medal, the community has used various combinations to generate the following medal distribution.
From your Main Menu, you can see your progression to the next tier. If you are winning more than losing, a percentage meter will be shown beneath your medal. Once you cross 100%, you will move to the next tier. However, if you tend to lose more, the percentage meter may disappear, indicating you might be on the brink of falling to the previous medal tier.
Other Aspects of Dota 2 MMR
Ranked Roles/ Ranked Classic
Ranked matchmaking is divided into two categories - Ranked Roles and Ranked Classic. With the former, players choose their roles beforehand, while with the latter, no roles are assigned to any of the five players.
When you queue for a match under ranked roles, your medal tier might be below the one displayed on your Main Menu. This is because of your skill level in that particular role. Support players might be more skilled at playing support than a core role so that they will have a Legend 4 medal on the Main Menu, but their tier will be displayed as Legend 3 in the drafting stage when they queue for a core role. Valve likely implemented this to ensure that you do not have to compete with the toughest opponents when queueing for your weaker roles.
How Much MMR Do You Gain When You Win/Lose a Ranked Match?
Valve changes this from time to time but currently, you gain or lose 20-30 MMR based on the outcome of the game. Generally, you lose or gain 20 MMR when you play in a party and 30 MMR when you queue alone. At times, this observation may differ.
Average Dota 2 Medal and MMR Leaderboards

However, if you are a cut above the rest, you can see your name on the Dota 2 MMR Leaderboards once you reach the top of Dota 2 ranked matchmaking, the Immortal Bracket. Dota 2 MMR leaderboards represent the rankings of players region-wise. Valve updates it every hour. A player needs to play "At least 14 ranked games in the last 21 days in the same division (region)" to be eligible for the Dota 2 MMR leaderboard.
How to Unlock Ranked Matchmaking in Dota 2?
When you open Dota 2 for the first time, you will not be able to queue for ranked matches. To unlock ranked matchmaking, you need to have 100 hours of playing Dota 2. Remember that this playing time is different from the time that shows up in the Steam Client. Dota 2 may be open for 100 hours, but if you have only played a small number of matches, the playing time that counts towards unlocking ranked matchmaking may be less than 100 hours.
Any Dota 2 game mode will count towards this 100-hour goal though we recommend that new players spend some time playing unranked and turbo matches before jumping into ranked matches. The Dota 2 tutorial might also come in handy for new players.
If we consider an average Dota 2 unranked game duration, it will likely take around 150 matches to fulfill the 100-hour quota and unlock ranked matchmaking.
After you pass the 100-hour mark, just enter your mobile number and link it to your Steam account. This will enable ranked matchmaking.
You will then need to play 10 matches to calibrate your matchmaking rating (MMR) and determine your skill level. MMR is believed to be derived from your performances and the number of wins and losses in unranked game mode, along with similar factors in each of these 10 ranked calibration matches. However, Valve has never publicly revealed the exact factors behind it.
