There are two ways to play. Blind and Hosted.
Blind Bad Movie Bingo is when nobody in the group has seen the movie. Everyone then fills out their Bingo card with things they think they will see in the show. It could be a physical object in a scene, a line of dialogue, a plot twist, a specific character, prop, etc. Get the idea? This version of BMB is typically for groups that already have a few BMB parties under their belt.
Hosted Bad Movie Bingo can be used to introduce new people to the game or to ensure that the game is entertaining. Before the movie, guests can create their own bingo boards using the pre-made boards within the app. For some who have never played before, creating a custom (blind) board can be difficult and the pre-made boards can be a life saver.
