Of course, this includes the four participating former and reigning world champions. Another four groups are led by experienced TAC teams who have themselves organized many tournaments and are rules-proof. The group spokespersons are supposed to support inexperienced teams and help them with rule questions, for example. As there are a few teams at this World Championship who have never played an official TAC tournament, the task of these teams is particularly important.

The group heads are: Eh wuascht (TAC World Champion 2019) / TiciTACa (TWC 2017) / TAC WG (TWC 2015) / Dreamteam (TWC 2011) / Die BeTACten, Spieletoyfel / TAC-Team-Stuttgart and TACTräumer.
