This is criteria 1 in the listed above. Months back a friend and I queued unranked both of us were 4k players we got a 3 stack of 1k players on our team. For ranked, you know your rating, and for unranked you don't. A surprising match outcome will tend to cause an increase in uncertainty. The Spring Cleaning Update Feb. We assign each player an MMR, which is a summary metric that quantifies your skill at Dota 2.

Win count is also not useful as indicator of skill, and the matchmaker does not use it for that purpose. We do try to group players by their level of experience criteria 3 in the list above , primarily because we have found that players at the same skill level but different experience level differ in their expectations of how the game is to be played.

The difference in experience between 40 games and games is considered to be about the same as the difference between games and You can visualize the impact of goals 2 and 3 with a chart where number of games played is the horizontal axis and MMR is the vertical axis. If two players are close together in the diagram, they are considered good candidates to put into a match together.

Players who are far apart are considered a poor match. The typical career trajectory of a player new to Dota 2 as he gains experience and moves towards the right is to gradually move upwards as their skill increases. When skilled players create new accounts, they follow a bit different trajectory.

Their MMR rises relatively quickly, placing them into the top lefthand corner of the diagram, where they will be matched with other players whose skill is high relative to their experience level.

When parties are involved, things get a bit more complicated. Parties often contain players with a wide discrepancy in skill and experience. For the purposes of measuring the goodness-of-fit criteria listed as 2 and 3 above, the matchmaker assigns each party aggregate skill and experience numbers. It is these party numbers that are used rather than the individual. In general, when a party with a wide skill range is matched with a solo player, the solo player will have skill and experience near the average of the party.

If you notice that one player seems to be significantly less skilled than the other players in the match, it is very likely that they are partied with a high skilled player. We account for this in two ways. First, we track your skill when queuing alone separately from when queuing in a party. Second, we adjust the effective MMRs based on the number of players in the party and the distribution of skill within the party. Observe that the average adjusted MMR for all of the parties is around When the players on a team are sorted by adjusted rank, as they are above, the solo players tend to be bracketed above and below by players playing in parties; furthermore, a party with a smaller MMR spread party F tends to get bracketed by a party with a larger MMR spread party D.

These patterns are typical. Party F, which is formed of players of more equal skill, received a lower bonus. These adjustments were determined using statistical tools more on this below , but an intuitive explanation is that your performance improves more when partying with a higher skilled player than it does when playing with another player of your same skill.

Measuring success in matchmaking is difficult. This includes the members of the Dota 2 team! Fortunately, we gather a lot of it. For example, you might wonder how we determined how to adjust effective MMRs to account for the fact that players in a party tend to perform better than players of equivalent skill queuing solo. We used a statistical tool known as logistic regression, which essentially works by trying to create a function that predicts the odds of victory.

This function contains several coefficients which determine the MMR bonus given to players in a party. Then we use numerical techniques to solve for the coefficients that produce the function which is most accurately able to predict the match outcome.

To help tune this threshold, we start with a measure of match quality. The ultimate goal of matchmaking is fun, and we have several metrics which we use to measure match quality. One such metric measures balance, based on the difference in gold farmed. This is easily visualized on the gold difference graph. Find the last time when the graph crosses zero, and then measure the area between the horizontal axis and the graph. In general, the smaller this area is, the closer the game was.

Although at one point in this match the Dire had a 10K gold advantage, the Radiant came back and then pulled ahead, only to have their gold lead reversed again. Despite the fact that at one point in time one team appeared to have a significant lead, our balance calculation judges this match a close game. Armed with this metric among others we have an experimental way to tune the wait time thresholds.

We make an adjustment to the threshold, and then observe what this does to the quality of matches, as measured by the distribution of the match balance metric. Hopefully this blog post has given you some insight into how the matchmaker currently works, as well as how we evaluate success and make design decisions. Like most everything else we do, matchmaking is subject to constant reevaluation. Matchmaking will never be perfect, and the technical details in this post refer to the current state of affairs and are likely to change as we find better approaches.
