GO Battle League
The GO Battle League is a feature in Pokémon GO for competitive, online Trainer Battles. It was first introduced on January 28, 2020.[1]
Rules and mechanics
Official rules for the GO Battle League were first announced on December 11, 2019.[2]. They are as follows:
- A season is a predetermined period of time during which players can battle to increase their rank and rating. At the start of a season, all players start from Rank 1 and can work their way up to Rank 10. A rating is assigned once the player reaches Rank 7, and it is recalculated upon finishing a set of five battles.
- Prior to receiving a rating, players will be randomly matched against other players of the same rank. After receiving a rating, players will be matched with those of a similar rating; a Rank 10 player that has fallen to a 3,400 rating may be matched against a Rank 9 player of a similar rating.
- GO Battle League matches take place in all three leagues: Great, Ultra, and Master Leagues. Only one league is available during a period of time, and the leagues will rotate throughout the season.
- Winning a match increases a Trainer's rating, and losing a match lowers it; currently, a tie counts as a loss. If the timer expires, the Trainer having the most remaining cumulative HP among their remaining Pokémon wins. Once a Trainer's rank moves up, it will not drop down for the remainder of the season.
- Teams with multiple Pokémon of the same species are not allowed. As with other Trainer Battles, Ditto and Shedinja are also ineligible to participate.
- Players can unlock a set of five GO Battle League matches by walking 3 km* or immediately by spending PokéCoins. After unlocking a set, any additional distance traveled will be rolled over towards unlocking the next set. A player can only participate in at most five sets (or 25 GO Battle League matches) per day, but afterwards, can still accumulate distance for the next day's set.
- The PokéCoin cost to immediately unlock the next set depends on how much distance left is needed to be walked:
200 if at least 2 km remaining- 100 if at least 1 km remaining
- 50 if less than 1 km remaining
- The PokéCoin cost to immediately unlock the next set depends on how much distance left is needed to be walked:

Rewards
|
This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: Exact amounts of Stardust awarded for finishing a set |
Trainers can earn up to five reward bundles per set for winning in the GO Battle League. Before starting a set of battles, the Trainer can choose either basic or premium reward track. A Premium Battle Pass is required for the premium reward track, which has better rewards than that of the basic. And upon finishing a set of five matches, the player will earn Stardust based on how many matches were won. The available rewards for both tracks improve as the player moves up in rank.
