How does matchmaking work in Roller Champions? No, fans are not taken into account when matchmaking. Does my number of fans impact my matchmaking? His MMR moving from ≈ 2000 to ≈ 2400.Īs you can see, both the difference in skill value and the uncertainty factor influence the change in MMR and how it is updated. His update is an increase, which will be higher due to the uncertainty factor being larger as well, Player 2 goes up to μ ≈ 24, while his uncertainty factor decreases to σ ≈ 5.5. Player 1 was probably having a bad day, allowing Player 2 to sneak in a last-minute goal and claim victory. ![]() His MMR moving from ≈ 3000 to ≈ 2800.įor Player 2, since he is a new player with a few losses to his record, his skill value is lower, but his uncertainty factor is much higher than Player 1’s (μ ≈ 20, σ ≈ 6). If Player 1 would have lost against someone much closer to them in skill value, the change would have been closer to: μ ≈ 29.8. Player 1’s skill value would decrease, resulting in something like: μ ≈ 28. Player 1 and Player 2 face off, with Player 1 ultimately losing. Player 2, on the other hand, is a newer player that has faced some setbacks, but is sticking to it. Let’s say Player 1 is an above-average player (μ ≈ 30) and has been playing at this skill level for a while, meaning her uncertainty factor is low (σ ≈ 2). Note that the values in the example do not reflect the actual updates that will occur but are to give a clear look at the system. ![]() Let’s look at an example with Player 1 and Player 2. This is also where the uncertainty factor comes in, as the more confident the system is with the information provided, the smaller the updates to MMR will be. If the result of the match was an unexpected one, with a high skill player losing to a low-skilled team, the skill update will be larger and vice versa. The outcome of the match is the sole information used to update MMR. What this means is that the more you play, the more information the system gets the more information the system gets, the more certain the system becomes of your skill. Skill values are derived from a probabilistic estimation. The uncertainty factor is used during the updates after matches. Skill value ranges from 0 to 50, with a new player starting at 25. The skill value represents the ability to win games. A player’s MMR is proportional to their skill value 100 μ. MMR is a combination of a skill value (μ) and an uncertainty factory (σ) to reach a 4-digit number. However, if the difference is lower, the more even the matchup is theoretically. The higher the difference, the more favorable the outcome will be to the better-rated player. In Roller Champions, we assign an MMR to each player, which is reflected in our leaderboard system.Ĭomparing the MMR of two players gives an indication of the probability of one player winning over the other. ![]() In order to give players a better idea of how this system works, we’ve put together an FAQ for this dev blog, so we can hopefully address some of those curiosities! What is Roller Champions MMR? During our test phases, we noticed that our community had questions about the matchmaking and MMR (Matchmaking Rating) system in Roller Champions.
