Mechanics of multiplayer online battle arena games A game of Dota 2 in progress, showing the Radiant team inside their base at the beginning of a match Dota 2 is a multiplayer online battle arena MOBA video game in which two teams of five players compete to collectively destroy a large structure defended by the opposing team known as the "Ancient", whilst defending their own.

Valve has stated that matchmaking tries to fulfil several criteria: The teams are balanced. The discrepancy in skill between the most and least skilled player in the match is minimized. The highest skill Radiant player should be close to the same skill as the highest skill Dire player. The discrepancy between experience measured by the number of games played between the least experienced player and the most experienced player is minimized.
This figure is assumed to be skewed upwards, as it is generally believed that newer and less skilled players are less likely to display their MMR publicly, and therefore are not considered in the data analysis. Uncertainty Uncertainty is the standard deviation of a player's MMR. Players with high uncertainty are more likely to be matched with players that differ more greatly in skill level, and vice versa. New accounts with few games played tend to have high uncertainty, while older accounts with many games played tend to have low uncertainty. Since normal and ranked matchmaking are tracked separately, a player who has many normal games will still experience high uncertainty in ranked matchmaking if they have only played a few ranked games, and vice versa.
