because x10 used an exploit on breeze ...the cypher cam that was used by giants before

Man, you are left behind by train

The teams are all split into groups of 4, (A, B, C and D). After that each team in the group will play every other team in the same group in a Bo2 (best of 2).
If the team gets a 2-0 win then the team gains 3 points, if they tie 1-1 then both teams get 1 point. At the end of all the matches, the top 2 teams from each group go into the playoffs where the top 2 make it to Berlin.

Now I'll explain why BOOM can qualify and X10 can't, the tie breaker rules are that if there is a tiebreaker in points then the round differences will be compared, by comparing the map where X10 won with the map that BOOM won, you cna see BOOM won 13-6 while X10 won 13-7, this means that BOOM is ahead as they won with more rounds.

TL:DR: Boom won by more rounds if you compare the games

Since BOOM and X10 have equal points, we have to break the tie.

Here is the order for tie-breaking -

1) Head-to-head maps - Equal maps won (1:1) TIED
2) Head-to-head rounds - BOOM won more rounds (13 + 7) against X10 (13 + 6)
3) Round difference

Thank you....

then if x10 wins against baam, can someone explain how x10 will qualify instead of boom?
