ARAM Scoring Version 2 compares each stat with the best of the other 9 players. Perfect scores drop from 1 game in 10 to about 1 in 36.
New ARAM ladders use ARAM Scoring Version 2, a simpler scoring rule. Each stat is compared with the best of the other 9 players in your game, and full points need a 20% lead.
Under the old rule, one ARAM ladder game in ten ended at a perfect 100. A score that common stopped telling you anything about how well you played. With the new rule, a 100 means you beat everyone in the game on every stat, and your team's result no longer pushes your score up.
The old rule rewarded being on a team that won big, not just playing well. ARAM scores have always used three stats: KDA (50 points), Life Points (25) and Gold (25). The problem was how each stat could reach full points.
Each stat had two ways to full points, and you got whichever was better:
The lobby path: beat the best of the other 9 players by 20%.
The team path: your number compared with your best teammate's, multiplied by how far your team was ahead of the enemy team.
In a one-sided game, the team path was easy to max. Take KDA: if your team's KD was double the enemy's, you got the full 50 points with just 83% of your best teammate's KDA. Your best teammate at 6 and you at 5 meant full KDA points, even if you weren't the best player in the game.
The same shortcut existed for Life Points and Gold. So the strongest players on a stomping team could hit 100 without leading the game in anything. Players noticed: in our community chat a 100 was called routine, and repeated 100s were reported as cheating when the formula was the cause.
Perfect scores drop from 1 game in 10 to about 1 in 36. We replayed 4,449 real ARAM ladder games from the two weeks before October 28 through both rules. Our replay matched the scores those games actually received to within half a point in 98.7% of them.
Share of ARAM ladder games | Version 1 | Version 2 |
|---|---|---|
Scoring exactly 100 | 10.0% | 2.8% |
Scoring 90 or more | 40.4% | 22.1% |
Median score | 86.1 | 75.6 |
Scores go down across the board, but because everyone is measured the same way, games keep nearly the same order from best to worst (a rank correlation of 0.93 between old and new scores). Ladders rank players against each other, so standings barely move.
Each stat now has one comparison: your number against the best of the other 9 players, teammates and opponents alike. Full points need a 20% lead over that player. Below that, you get your share.
Points for a stat = your value ÷ (1.2 × the best of the other 9), up to the stat's full points.
An example with KDA, worth 50 points. Say the best KDA among the other 9 players is 5. Full points sit at 6, which is 20% more.
Your KDA | KDA points |
|---|---|
6 or more | 50 / 50 |
5 (matching the best) | 41.7 / 50 |
4.5 | 37.5 / 50 |
The three stats and their weights are the same as before:
KDA (50 points): (kills + assists) ÷ deaths. With no deaths, (kills + assists) × 1.2. Attach champions like Yuumi are left out when finding the best KDA.
Life Points (25 points): the larger of 80% of your damage to champions or your healing on allies, plus your shielding on allies, plus the damage you took. Damage taken counts less if your deaths are more than half the other players' average.
Gold (25 points): the total gold you earned.
ARAM ladders switch to the new rule as each one closes and is replaced. Ladders already open keep the old scoring until they close, so for a short while both run side by side. A ladder's Rules show how it is scored.
Your scores will be lower, typically by 4 to 7 points a game. Everyone is measured the same way, so your place on a ladder stays about where it was.
A 100 is rare and earned. It means you led everyone in the game by 20% on KDA, Life Points and Gold.
Your team's result no longer counts. A big team win no longer lifts your score.
Every point is explained. Each game's breakdown shows your number, the best of the other 9, and the value that earns full points, for every stat.
A short walkthrough appears the first time you open a new ARAM ladder.
Does this change who wins ladders? Rarely. Scores drop by a similar amount for everyone, and games keep nearly the same order from best to worst.
Why a 20% lead? Matching the best other player already earns 83% of a stat. Full points should mean you clearly outplayed everyone in the game.
What about ladders I'm already in? They keep the old scoring until they close. The ladders that replace them use the new rule.
Why does my profile show a different ARAM score for the same game? Your profile's ARAM stats still use the old scoring for now. Ladder scores use the rule of the ladder you played.
Can I still get 100? Yes. In our replay, about 1 game in 36 scored 100 under the new rule. Lead the lobby by 20% on KDA, Life Points and Gold.
