Play ins

How does play ins work sorry. What will happen if every team gets 1 win and 1 loss? Eg A beats B B beats C and C beats A.

Win 2 and you're in playoffs. If all teams go 1-1, it goes to map differential. If there is a tie, then it goes to round differential.

round robin and pray everyone doesnt go 1-1 or else theres some wierd tie breakers like round and map differnetial

Will there be betting lines available for play ins?
