Draft against a bot or a friend

Draft against the computer, then see which picks were better and why.

Setting up your draft…

How the draft arena works

  1. Draft a full champion select in the real solo-queue pick order, against the computer at a strength you choose or against a friend, on one screen or from two devices with a room code.
  2. You pick for your side's seats as they come up; the other side drafts for itself.
  3. When the draft ends, every pick is graded: how many champions were better for that seat, which pick cost your side the most, and by how much.

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: a blue draft graded pick by pick

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

You draft Blue. Each row is one of your picks, ranked among every champion that could have filled the seat at that moment.
