Answer

A possible partition gives the first set:

tone, canine, listener, freighter → hidden numerals

Second set:

romans, puking, minimalistic, incubate → hidden countries

Third set:

tinned, hijack, shoebill, stomach → hidden male first names

Fourth set:

ununoctium, snapdragon, asterisk, duchesses
Uno is a card game, snap (cards) or go, risk and chess are games
