How does one get more tickets?

[hr]Is there a way to get more tickets besides paying physical money for them? I've beaten 3 council ricks and 16 other ricks, do I just not earn them any more?

Havent tried multiplayer? in there you win 1 ticket when you lelvel up your rick also there is a mission when you get 3 rick levels you win a ticket and plus every week a special mission comes out (cacht X mortys or evolve or win X battles etc). when you complete it you get 5 tickets in campaing you get 5 beating a council member or get 1 randomly througt boxes in the dimensions.
