Here is the rule summary.

Each match is a best of 3 maps.

Each push map is a first to 5. Each half only goes to 3 points. (So you'd have to win 3 in the first, then 2 in the second, the config will always limit the half score to 3).

Koth maps are first to 4.

Stopwatch maps (cp_gravelpit) are who can attack the fastest twice.

This is double elimination, meaning you must you two MATCHES to be completely eliminated.
