There are many different types of announcers that work at bingo halls. Some are called floor managers, while others are simply named announcers.
Floor managers typically oversee all aspects of the game, from setting up the games to announcing the results. They are responsible for ensuring that players have a good time and that the game runs smoothly.
Announcers typically announce the numbers as they appear on the screen, as well as any special announcements or prizes that may be available. They are also responsible for providing players with information about the game rules and how to play.
In some cases, announcers also provide commentary during the game.
