After winning too many CSGO matches, as a new player you cannot play the sparring maps.
The ability to play sparrings in Counter-Strike: Global Offensive was added on July 31, 2019. This one does not currently have any rank restrictions, and the games themselves do not affect it. Nevertheless, if a new player wins too many matches and tries to play a sparring – the system will not allow him to do so.
What is displayed for new players who want to play a sparring game and have won too many games?
In the screenshot below you can see the message being displayed to new players wishing to play a sparring game. The system tells the user to wait for the user to play sparrings and there is absolutely nothing you can do about it.
It seems that the developers wanted to thwart cheaters, who usually win their games. This does not make sense, however, as sparring matches, unlike regular matchmaking, have no influence on rank.
It is difficult to determine why the developers introduced such a restriction. According to some sources, Valve wants to see if the number of cheaters per match will decrease. If this idea has a positive effect, it will also be used in ranked tournaments.
