# 9.0 - UPR Ranking System

Universal Player Ranking (UPR) System

**Inside Our Universal Player Ranking (UPR) System**

Our UPR system resembles the Elo ratings and experience points familiar to competitive gamers.

UPR scores will rise or fall after every game in proportion to:

* The player's skill level / Their opponents' skill level
* The type of game they've chosen to play in tournament competition
* The completion of various rare or difficult achievements in games or through ESTN tournament play.
* Other assessed metrics to be determined

|            | UPR1  | UPR2  | UPR3  | UPR4  | UPR5   | UPR6   | UPR7   | UPR8  | UPR9   | UPR10  |
| ---------- | ----- | ----- | ----- | ----- | ------ | ------ | ------ | ----- | ------ | ------ |
| Entry Fee  | $20   | $40   | $60   | $80   | $100   | $120   | $140   | $160  | $180   | $200   |
| Prize Pool | $2000 | $4000 | $6000 | $8000 | $10000 | $12000 | $14000 | $1600 | $18000 | $20000 |

UPR points encourage consistent play and provide stable “gating” mechanisms that prevent players from moving too rapidly through league rankings, or from attempting to engage in unfair competition with lower- skilled players that have weaker UPRs.

By storing all player performance data on the blockchain and enforcing multi-factor authentication, we ensure that no player will attain their UPR and attendant rewards unfairly through hacking or via surreptitious use of higher-skilled "ringers".
