How does MIKROS categorize players?
MIKROS categorizes players based on various scores that range from 1-10.
The "Activity Score" tracks how active players are on your games. The higher the score, the more time they spend on a certain game.
The "Spending Score" tracks players' spending habits. The higher the score, the more money they spend.
The "Reputation Score" monitors player behavior, and tells you if a user uses exploits/hacks on a regular basis or regularly exhibits toxic behavior.
Finally, the "Tendency Score" tells you if a user will enjoy playing your game or not, which can assist with maintaining user retention for your games.
