Player ratings and all ranked lists are recalculated whenever there is new data, or at least weekly otherwise (this is important because RD values decay over time). All ratings were last updated on July 3, 2011 . The database now includes 119,740 matches, and 3,248 players from 13 countries.
The complete list of rankings is available below. The most important ranking, used for all official purposes, is the Ranking of Active Players, by Lower Bound.
To generate customized rankings, such as restricted by league or country, or using a custom definition of "active", please visit the Custom Rankings page.
