Before you play any competitive game, your rank will be unassigned. Once you have 10 competitive match wins, you will be assigned your first rank. There’s a total of 18 different ranks (aka skill groups) in CSGO. Depending on how you did personally and how long it took you to get these ten wins, you will be allocated one of the 18 ranks in CSGO.
