Bingo has been popular in land-based bingo halls for decades. It has adapted well to the internet age, too. There are several types of bingo to choose from.
30-ball bingo uses a 3 x 3 grid of numbers. Players need to match all nine numbers on the card to win the game.
90-ball bingo is the most traditional form. The bingo card has three rows with five numbers appearing on each. Three prizes are available in each game. The first is awarded to the first player who completes a line. The second is awarded to the first player completing two lines. The big prize goes to the first player to complete a full house.
80-ball bingo uses a 4 x 4 grid. However, instead of marking off all 16 numbers to win, players must complete a predetermined pattern on the grid. This could be collecting the four corner numbers, for example.
Finally, there is 75-ball bingo. This adopts a 5 x 5 grid with numbers in every position except the centre one. To win, the player may have to complete a line or achieve a predetermined pattern depending on the rules in force for that game.
In each case, online casinos usually allow the player to mark their own numbers or choose the computer to do it for them.
