Although it is never explicitly stated, it seems that bingo was a regular activity at the Lodge. Archie, Jughead, and Betty all seem to enjoy playing the game together, and Veronica occasionally joins in as well.
In one episode, Veronica even suggests that they set up a bingo game at the Southside Serpents clubhouse to raise money for charity.
It’s unclear exactly how bingo is played in Riverdale, but it seems to involve drawing cards with different values and matching them up according to a set list. Players can either call out bingo when they find a match or else the game will automatically call out bingo whenever a player makes a set of three calls.
If players get all of their cards filled in during one turn, they can earn bonus points.
Bingo may not be a major part of the show, but it’s an interesting little detail that adds some character dynamics and social interaction to Riverdale. It’s also an easy way for the show to raise money – just set up some cards and let the players go!.
