DD - MMR System

Learn how Dimension Drill ranked matches calculate MMR gains, losses, and protection.

Dimension Drill uses Matchmaking Rating (MMR) to rate teams in Ranked Matches. Higher MMR represents a stronger competitive rating.

Each match updates MMR based on the result, the teams' ratings and the final score margin.

MMR helps match teams with opponents of similar skill.

How MMR works

When a Ranked match ends, the system evaluates the following factors:

Factor	Effect
Match result	Determines whether MMR is gained or lost.
Team MMR difference	Sets the expected MMR change.
Score margin	Adds a bonus for decisive wins.
Close match	Reduces the losing team's MMR loss.
Underdog performance	May prevent an eligible team's MMR loss.

Team MMR difference

The system compares team MMR before the match. An upset win earns more MMR. Beating a lower-rated team earns less.

Equal-rated teams

If both teams have 1,000 MMR, the standard change is:

Result	MMR change
Winner	+16 MMR
Loser	-16 MMR

Different-rated teams

The expected outcome changes the base reward.

Matchup	Expected result	Example winner reward
1,000 vs. 1,000	Evenly matched	+16
1,200 vs. 900	Higher-rated team wins	+8
900 vs. 1,200	Lower-rated team wins	+28

Beating a stronger team earns more MMR. Losing to one can be less punishing.

Winner performance bonus

Winning teams can earn an additional performance bonus. The bonus increases with the victory margin.

The maximum bonus is +10 MMR.

Victory margin	Bonus
Very close	Little or no bonus
Moderate	Small bonus
Large	Larger bonus
Maximum	Up to +10 MMR

Example: decisive Team Deathmatch win

Team Deathmatch score of 9-0 has a 60% margin. Team Deathmatch uses a maximum score of 15.

Calculation	MMR
Base win	+16
Performance bonus	+6
Final gain	+22

Loss protection

Losing teams can qualify for one of two protection systems.

Close Match Shield

Matches with a normalized score margin below 15% count as extremely close. The losing team's MMR loss is reduced by 50%.

Calculation	MMR
Normal loss	-16
Close Match Shield	50% reduction
Final loss	-8

The shield uses the normalized score margin, not only the point difference.

Underdog Shield

The Underdog Shield protects lower-rated teams that perform well against stronger opponents.

Both requirements must be met:

Requirement	Condition
MMR difference	The losing team was 150+ MMR lower.
Performance	The team meets its mode's threshold.

Performance thresholds

Game mode	Required performance
Team Deathmatch	15+ kills
Blood and Gold	12+ Gold

When both requirements are met, the losing team loses 0 MMR.

Calculation order

1. Compare the teams' MMR.

2. Determine the base MMR change.

3. Calculate the victory margin.

4. Apply the winner performance bonus.

5. Check the losing team's protection eligibility.

6. Apply the final MMR change.

Score limits

Each mode's score limit is used to calculate the victory margin.

Game mode	Maximum score
Team Deathmatch	15
Shapeshift	60
Blood and Gold	99
Cart Contest	100

Examples

Decisive victory

Two teams each have 1,000 MMR. The final score is 9–0.

Team	MMR change
Winner	+22
Loser	-16

The winner receives +16 base MMR and a +6 performance bonus.

Very close match

Two teams each have 1,000 MMR. A Team Deathmatch ends 2–0.

The margin is below 15%. The losing team receives the Close Match Shield.

Team	MMR change
Winner	+17
Loser	-8

Underdog performance

A 900 MMR team loses to a 1,100 MMR team. The losing team is 200 MMR lower and meets its mode's performance threshold.

Team	MMR change
Winner	Normal expected gain
Losing underdog	0

MMR is calculated automatically after every Ranked Match. The final amount varies by team MMR, mode, score, margin, and protection rules.
