Perfect Swing uses an ELO ranking system. All players start with 1,000 ELO points represented by a trophy icon. When playing against an opponent, the winner will gain ELO points and the loser will lose ELO points. The matchmaking system will use the ELO score to find a fair and competitive match. In the event that players are matched with someone with a much higher ELO than them, more points will be gained and lost based on how far apart their ratings are.
Every Sunday at 10:30 PM PST everyone's ELO score goes down by 100 points, with 1,000 being the minimum, anyone with less than 1,000 is brought up to 1,000 points again. Rewards are distributed at this time, and the bottom 30% of players will go down a tier, and the top 30% will go up a tier, as long as there is 300 players ready to create a new tier.
Playing a match against the AI will not effect your ELO score, but will still award Honor Coins.
