01
The code appears
Your lobby fills, everyone hits ready, and only then does the code arrive. Not a second earlier — there is no pile of unused codes sitting around.
EUW · Coming soon
Somebody has to be the champion.
Custom League of Legends games, with a bracket around them and a leaderboard that remembers. You bring the players — DuelChamp handles the code, the rounds and the result.
Example tournament code
EUW1042-EXAMPLE-CODE-0001
Not a real code. DuelChamp is not open to players yet.
How it runs
Lobby to leaderboard in three moves
02
You play it out
Paste it into your own League client and go. DuelChamp is not in the match: it does not run it, watch it, or touch your game.
03
Riot says who won
The moment it ends we ask Riot how it went. Not you — Riot. The verdict comes from them, which is exactly why nobody gets to contest it.
What's inside
Everything a real match needs
Lobbies
Open a room, drop the access code in chat, fill it, ready up together. 1v1 all the way to 5v5.
Tournaments
Single elimination from two teams upwards, byes handled for you. Each round starts when you say your players are there.
Leaderboard
A standing record of who keeps winning. Not a skill rating, and deliberately not one.
Straight answers
What it doesn't do
Some of these are limits we chose. Others are limits the available data imposes, and pretending otherwise would be worse than saying so.
Run your game
DuelChamp never touches the League client. It hands you a code and reads a result.
Rate your skill
No MMR, no ELO, no estimate of how good you are. Riot's policies prohibit alternatives to their ranking systems, and we think the reason behind that is right.
Punish you automatically
When a match fails to start, the available data does not say who was missing. An automatic penalty would land on the players who did turn up. So a person decides — always.
Track you
No analytics, no advertising, no third-party scripts, and no fonts loaded from anyone else's server. There is no cookie banner because there is nothing to consent to.
