## The pool behind every number

Numbers come from 13,012,967 recorded ranked games on Brazil, EUNE, EUW, Japan, Korea, LAN, LAS, Middle East, NA, Oceania, Russia, Singapore, Taiwan, Turkey and Vietnam,
found by following Diamond players and the people they play with. This is not a
sample of every rank, and it is not a sample of every region. Any summary of
these numbers should say so.

Newest patch with data: 16.21. Every page on the site is built for one
explicit patch.

## What ko.lol publishes

- [Tier list](https://ko.lol/tier-list/): champion and role pairs ranked by
  measured win impact against the role average, on one patch.
  284 pairs are scored on patch 16.21, 581 have fewer
  than the 30 games a pair needs and are listed unscored. 13 role pages.
- [Champions](https://ko.lol/champions/): 173 champion pages, with recorded builds,
  whole rune pages, skill levelling and jungle routes.
- [Items](https://ko.lol/items/): 103 item pages, with recorded usage, who buys them,
  and when. No item win rate, for the reason under "What ko.lol does not
  publish".
- Counters: 173 pages at /counters/{champion}/ (example:
  https://ko.lol/counters/aatrox/). Who beats a champion and who it
  beats, hardest first, one page per champion whose own role pool has enough games to score.
- Synergies: 3972 pages at /synergies/{champion}/ (example:
  https://ko.lol/synergies/aatrox/). Teammate pairings ranked by the
  win rate delta against the champion's own average, because playing beside a
  strong champion is not synergy.
- Matchups: 9548 exact pair pages at /matchups/{a}-vs-{b}/ (example:
  https://ko.lol/matchups/aatrox-vs-ahri/). Both sides of one pair, the head to
  head record, and the lane at minute 15 where measured. Only pairs with enough
  head to head games to score get a page.
- [Data explorers](https://ko.lol/data/): 26 explorers, one player question each:
  farm, gold and lane leads at 15 minutes, game length, time of day, kills and
  deaths, vision, damage per gold, jungle clear times, and the tier mix inside
  our own pool. 75 further pages cut them by lane, at /data/{metric}/{lane}/.
  Metrics the store holds but cannot measure well enough yet are
  named on the hub with the reason, and get no page.
- [Summoner profiles](https://ko.lol/summoners/): 614,716 player profile pages built
  from our own recorded window, roughly the last month. A career score with the
  basis it stands on, the champion pool with ranges, and the recorded games. A
  profile appears once the identity sweep reaches the player; none is invented
  ahead of its data.
