Deadlock MMR, matchmaking and low priority explained

How Deadlock matchmaking works, what Valve has said about MMR, when you can leave a game safely, and how abandon penalties and low priority work.

How Deadlock matchmaking works

Since July 30, 2026 Deadlock has two main queues. Standard Mode is unranked, has no limits on party size or skill spread, and adjusts the game for how experienced you are on the hero you queued. Ranked Mode matches you with players of similar skill and shows ranks that reset each season.

Either way you pick heroes before you queue, and the matchmaker builds teams from the whole queue so people get their preferred hero and both sides have a workable composition. Since 2024 it has tried to give each team at least two frontliners when it can, and an October 2025 change made it balance the rest of the roster as well.

Does Deadlock have hidden MMR?

Valve doesn't show you a hidden number, but the game clearly keeps an estimate of your skill. The Rank Points you gain or lose vary with what the matchmaker expected from the game, and each season's soft reset keeps some history of how you did against other players. That's MMR in all but name.

Before Ranked came back, the Skill Rating system (November 2024 to July 2026) was more open about it. You had a core MMR plus a rating for each hero as an offset from it, judged on your 20 most recent games with that hero, and your badge showed that rating, updated straight away. Valve hasn't said how much of that model carried over, so treat anything more specific you read about current MMR as a guess.

Parties and queue times

Standard takes any party size. Ranked takes solo players and duos only, duo partners must be within one rank of each other, and calibration games are solo. Eternus players can only duo with another Eternus within three subranks.

Valve has been upfront that the matchmaker works with whoever is in the queue. At high ranks, in smaller regions and at off-peak hours the pool is thin, so queues run longer and teams come out less balanced. If your games feel lopsided at 4am, that's why.

When is it safe to leave a match?

In Ranked it depends on when someone abandons. If a player leaves before the 5-minute mark, the game is voided for everyone except the leaver and their party, who take a loss, and the leaver gets penalties. Everyone else can leave without penalty.

After 5 minutes, the leaver gets penalties and their party takes a loss. The rest of their team has the game voided and can leave safely, but if they stay and win it counts as a win. If the whole team leaves, the other side gets the win.

The other team plays on as normal. If one of them abandons too, the same rules apply to them and their team, so nobody left in the game takes a loss and only a team that finishes and wins gets a result.

1. 01Wait for the on-screen message that says it's safe to leave. Don't guess.
2. 02Staying after a teammate leaves costs nothing and can still earn a win.
3. 03Going AFK isn't a loophole. AFK players get kicked automatically after a few minutes.

Leaver penalties and low priority

Leaver penalties start with queue timeouts and escalate to more and more low priority games. Low priority is a separate matchmaking pool, mostly for players who abandon games, though other bad behaviour can put you there too.

To get out you have to complete a set number of games, and that number goes up each time you end up there. Since a November 2024 change only wins count, so losing in low priority doesn't shorten your stay. You can't queue Ranked at all while you're in it.

Comms bans, reports and other sanctions

The behaviour system can take away more than matchmaking: it can temporarily remove your voice chat, text chat, pausing and reporting. Since the City Never Sleeps update on September 29, 2026, a player reported during a match and found abusing comms is muted for the rest of that game and gets a 30-day comms ban. You also get a notification when action is taken on someone you reported.

Reports cut both ways. Repeatedly reporting people who did nothing wrong can lose you the report button and land you in low priority. Any active sanction, comms bans included, blocks the Ranked queue until it ends.

How to stay out of trouble

1. 01Fix crashes and unstable connections in Standard, not Ranked. If you crash and can't get back in, the game can treat it as an abandon.
2. 02Mute instead of arguing. Muting a player also hides their map drawings, pings and chat wheel messages.
3. 03Report players for what they actually did, and only then.
4. 04After two bad games in a row, stop queueing. Tilt causes most abandons.
5. 05If you do land in low priority, play the hero you win most with, at your region's peak hours.

What could change

All of this is as of Ranked Season 1, which ends on November 5, 2026. Valve said at launch that the party and rank-spread limits might be too strict and could be loosened, and that future seasons will likely bring splits and hero recency requirements. Penalty lengths and the exact number of low priority wins have never been published, and they can change without a patch note.
