Bingo is a popular game at mobile casinos in Oman. Each game involves a caller, called a ‘bingo caller’ who draws numbered balls from a caller bag. Players buy tickets, called ‘bingo cards’ that bear a 5x5 grid containing 24 random numbers and a blank space in the middle. The aim of the game is to match numbers from the caller’s announcements to those on the player’s card and complete the necessary patterns. Patterns may vary from game to game but generally involve covering all five numbers in a horizontal line or forming a ‘speed pattern’, which is done by the player simply covering a row of five numbers.
