About CanWin

CanWin measures what a rune, item, spell or lane opponent does to your chance of winning in League of Legends, and at which point of the game it matters. Every number comes with how sure we are of it.

How CanWin is different

Most stats sites show win rates, which count how often games with an option were won. A win rate mixes what the option does with who picks it and in which games. CanWin scores every minute of every game with a win-chance model. It judges each choice against what the game looked like when the choice was made. Each option is compared with the most picked one in games with the same odds and patch, played by players as experienced. Every number says how sure it is. The guide explains how.

The data

The numbers come from 50,990 ranked solo queue games on patches 16.19–16.20, from Riot Games’ API. They cover 173 champions, with builds and runes for 190 champion and role pages. They were last computed on 28 Oct 2026. The guide’s data section says which games each page uses.

An option with too few games shows “Not enough games” instead of a number. Margins shrink as more games come in.

How the site is paid for

Ads will pay for it. They never change what a page says.
