Buckets
Use buckets to group players into cohorts, segmenting players to give them a better sense of competition.
For example, if you have a leaderboard with a million players configured with a bucket size of 100, each player will only access the scores for the other 99 players assigned to the same bucket.
When used together with tiers, the rules for tiers apply to each bucket, so if you have a "top 10%" tier, each bucket will have a unique "top 10%" of scores.
In addition to using buckets you can also get a range of scores centered around a player.
Unlike other options for leaderboards, buckets must be configured when a leaderboard is created and buckets cannot be modified or removed later. To use buckets in a game with an existing leaderboard you will need to create a new leaderboard with buckets configured.
