At the very top, it's possible to inflate your ranking by spamming games constantly. Blizzard wants their point systems to always look like they're providing bonuses rather than penalties.
So instead of deflating the ranks of the players in those two cases, they created the Bonus Pool, which rewards everyone else. In practice, LHK and Ryu are correct. Bonus Pool doesn't really do anything any more, and the two above issues are handled by the MMR algorithm directly.
But since it's a "Bonus", they have to keep showing it to players. Because psychology. Good to know. Live Events Next event in 58m. Shinee Bale 60 zelot 33 dr. BasetradeTV Blizzard YouTube.

For Random Teams, it is likely that the MMRs of all members are averaged first, then an opposing team with a similar MMR based upon a degree of uncertainty is located. Promotion By outperforming the rest of your league, it is possible to get promoted into a higher league.
This is because the system requires a certain degree of confidence before players can be moved to a new league, otherwise they would bounce around from league to league too frequently for leagues to be meaningful. That confidence is measured in two ways:. First, the player must prove that he is capable of maintaining a certain level of skill.
The below image should help demonstrate. When this moving average stabilizes within the confines of a division tier, a player can be promoted into that league. A player can also be instantly promoted to a league if his moving average exceeds the upper bound of that league. That is, if a Bronze player is only slightly better than the lowest-rated Silver players according to his moving average, that is not reason alone to promote him, even though he has crossed into the Silver MMR region.
If that player slumped, he would fall right back into Bronze within a couple of games, only to return to Silver a couple of games later, making his promotion far less meaningful.
In the picture above, the confidence buffer is represented by the yellow glow region. Note that these are the only two factors required for promotion. Division Tiers When you are placed in a league, you are placed into a division within that league. That division consists of up to players who are intended to be roughly the same skill level as of the time of placement. However, because the ladder population is broken down into quintiles with the exception of Master league which siphons a percentage from Diamond , certain leagues encompass a broader range of skill than others.
This means that divisions are not always equal in each league, which means the points earned in each division cannot always be directly compared with points in other divisions. This also means that at any given time, there are seven developing Bronze divisions, compared to Master league which generates divisions one at a time.
Grandmaster League The Grandmaster League is a special league consisting of the top players in a region as determined by moving average of MMR. After one week has elapsed in a season, the top players with the highest moving average — and who have bonus pools below 90 — will become Grandmasters.
The only way to be demoted out of Grandmaster League is to accrue bonus pool. Overview The last piece of the Starcraft II ladder puzzle is activity. Although the MMR requirements to join each league are constant, the skill level required to move into a higher league will change depending on the currently active population. This allows it to function as an activity metric, and by extension determine whether a player is active or not for the purposes of league apportionment.
League Population There are seven leagues, and the population of each is governed by the current active population:. The system dynamically distributes the population of active players across a constant range of MMR values, and league boundaries are fixed in relation to MMR.
The boundaries are based on MMR values selected by a prior distribution that will capture these certain percentiles. Furthermore, the league boundaries can be adjusted by Blizzard on the fly in the event that populations need to be normalized.
The one additional requirement to getting promoted is that you must play a game, because league changes only occur after a game. There are really no negative effects associated with going inactive. Your MMR does not decrease.
Your points do not decrease. Seasons last about two months. They must take part in 5 qualifying matches before being put into a league and division. After a hidden [4] period of time, their skill level will be reevaluated. Players gain points for defeating opponents, especially stronger opponents.
Before a match starts, players can compare their ratings — usually, one player will be "favored" over the other. If a player defeats a favored opponent, they will gain more points than if they defeat a weaker opponent. Players also gain points from a bonus pool sometimes called "rested points" [4] for periods of time they have not been playing for. Players gain these points at a slow rate when they're not playing, up to a cap at the end of the season.
When a player who has accumulated bonus points wins a match, they gain a share of bonus points equal to the number of points gained for winning the match. When a player gains points, they increase their rank and may even shift leagues. A player that loses points will, in turn, lose rank and can fall to a lower league.
On occasion, a player will face opponents from a higher league, in order to test their skill. Playing more games results in a more accurate skill level. The internal rating is not wiped or reset when league ladders are wiped and is separate from ladder points.
Each team has a separate skill rating. Individual teammates have very little effect on the team rating, except to determine what placement matches they are put in.
Under the free to play model of StarCraft II , players will need to achieve ten "first win of the day" awards to gain access to the ladder. Players qualified for the league following the first week of a season as of October 24, , the start of the fourth season. A list of the winners, updated in real time, can be found on the Grandmaster League page on the official Blizzard site.
Each league is split into divisions of about players from the same area of very similar skill levels. Tournaments held at the end of a season will determine division winners, who then compete for League championships.
Divisions have names such as "Silver Tal'darim Bravo". These names can be any reference to the StarCraft universe: the original game ex. The top eight players in each division qualify for tournament play. The pro league does not have divisions.
Prior to season 4 not all divisions were created equal, but this wasn't transparent. Blizzard removed these tiers, meaning someone's rank in their division is giving a more accurate representation of their skill. Ladders are compiled within the leagues.
