Mobile bingo is a popular game in Latvia that is typically played with paper or online cards. To play mobile bingo, the player is required to purchase a bingo card, which is a 4x4 grid with sixteen random numbers. The numbers range from 1 to 75. The number of numbers needed to win is determined in advance by the player. To win, the player needs to match the required pattern on their bingo card with the numbers that are called out. Additionally, players may utilize wildcards, which are also called free space, which can be used to mark off any called number on the bingo card.
The bingo caller will call out the numbers randomly. In Latvia, each bingo game will last approximately 45 minutes. After every game, the players can check their cards for the pattern that is predetermined. The first player to hit a pattern will be declared the winner.
