Many people believe Bingo is a horizontal game. This is because the bingo cards are typically laid out horizontally on the table. However, there is some evidence that suggests Bingo may in fact be a vertical game.
The main piece of evidence comes from the fact that players hit balls up and down a vertical track to try and match the numbers on their card. Additionally, the balls used in Bingo are typically smaller than those used in other types of games such as Roulette or Blackjack, which suggests that Bingo may be designed as a fast-paced game.
So, while it’s clear that Bingo can be played in either a horizontal or vertical format, it seems more likely that it is actually a vertical game.
