What is MMR?
In arena, you are playing against other players in the Axie Infinity ecosystem. You will be matched with players of the same skill level through your Match Making Rating (MMR).
For every win, your MMR increases, and for every loss, it decreases. The amount of SLP you can gain in Arena depends on your MMR. Using the table below, for example, if you have an MMR of 1800, you can earn 12-15 SLP for every win you get. Losing does not earn you any SLP.
