An announcer randomly selects numbers from 1 to 75, calling out each one while players mark the appropriate grid square if that number appears on their cards. In standard Bingo, the player's goal is to be the first to mark an entire row, column, or diagonal. There are 12 winning configurations.
According to a study published by Play OJO, one of the UK's bingo operators, they found that the number six is the most called number. The next one is followed by four. This applies to any match, including online bingo games. These numbers are often called for a game of chance despite the game relying on luck.
