Isn't it supposed to be only 20 games or am I missing something?

* - some players may get more games, since there are cases where it's not mathematically possible to give everyone exactly the same amount without duplicates. Getting more games is neither an advantage nor disadvantage.

That part. For someone else to get their 20th game, you needed to get 21.

Thanks Fizzer and Good Kid, I mistakenly though my opponent also got 21 games since we both got a game yesterday aswell.
