One pick

Solo queue is one pick in a lobby of ten. Five boards, one seat each, graded against every option you had.

Setting up your match…

How One pick works

  1. You get a real champion select with one seat on the clock: the picks made so far and the lane you are filling.
  2. Choose the champion for that seat. Five boards make a match, against the computer, a player who already answered the same board, a pro team, a friend or somebody at your level.
  3. Each pick is graded against every option you had: the model ranks them all by the win chance they leave your team, and shows where yours landed and what the best one was worth.

Grades come from KayLoL's draft model, trained on millions of ranked games. How often it calls the winner, on patches it never trained on, is published: the accuracy page

Example: one pick graded (blue mid, pick 9 of 10)

A made-up draft, graded by the model when this page was built: Emerald, patch 16.21, Europe West, champions only (no player history).

Blue so far: Vi (Jungle), Jinx (Bot), Thresh (Support), Ornn (Top). Red so far: Lee Sin (Jungle), Kai'Sa (Bot), Leona (Support), Darius (Top).

Blue Mid is on the clock, pick 9 of 10.
