kudos arent too bad to get. iirc its 30 for every ranked/casual/battle hub match you play. the 10th and 20th of each month is an event in the hub with golden cabinets that give double kudos. theres also the daily/weekly challenges that so far are just play or win matches from a cabinet. that

you also get 5 for offline vs matches meaning you can turbo controller it if need be.

you get some from world tour but i think its like 1 for every npc you fight with a character style. so technically exists but not worth going for. theres also a limited amount from character trials/guides
