The VPN routes only your matchmaking data over our VPN servers, this makes the game think you are from another location and as a result you will be placed into the closest lobby possible.
This process creates more variance on your lobbies resulting in increased chances of getting into easier lobbies over time.
We provide a Geo-Fence which you can use to really lock in your lobbies even further, Geo-Fencing allows you to decide where 100% of your games are played.
