Bingo is a simple enough game for anyone to have a go at. The purpose of a player is to complete a winning pattern with the numbers on their ticket before fellow participants. The undying popularity of this game of chance has lead to a proliferation of diverse patterns players can win with. Some of those are more exotic and elaborate than others which makes them more difficult to complete but this only increases one’s excitement of playing the game.
However, there is one pattern that never gets old since it holds the key to winning the biggest prizes in bingo. Of course, we are talking about the Full House pattern, which is also known as Blackout or Coverall in the North American version of bingo. This pattern is more difficult to achieve but is well worth the efforts because it awards winners with either fixed or progressive jackpots, depending on the bingo game.
The Full House Pattern in 90-Ball Bingo
In order to complete a Full House Pattern in 90-ball bingo, the player must mark off all 15 numbers on their ticket within the specified number of calls. The typical 90-ball bingo ticket utilizes 3 rows and 9 columns, with each row including 5 random numbers and 4 empty squares.
The tickets in 90-ball bingo are normally sold in strips of six so that each number from 1 to 90 would appear once on the six tickets. This makes it possible for players to daub a spot on their six-strip tickets each time the caller announces a number. Players who complete a Full House are usually awarded a share of a fixed or a progressive jackpot which gets divided equally between all winners who cover their tickets in full.
The Blackout Pattern in 75-Ball Bingo
The Blackout pattern in 75-ball bingo is similar to the Full House as players are again required to mark off all the numbers on the tickets in order to win a jackpot share. However, one such coverall is more difficult to complete in this instance because of the different grid 75-ball bingo uses. In this version of the game, the ticket has 5 rows and 5 columns, containing 24 numbers since one square in the centre is blank.
Blackout patterns are more common in bingo games with progressive jackpots where players must mark off all their ticket numbers within a predetermined number of balls. If no one succeeds in doing this within a session, the progressive jackpot grows and remains to be won in the following sessions. In bingo games with fixed jackpots, there is no predetermined number of calls you need to achieve a Blackout in. Instead, the pattern is played until a player eventually completes it no matter how many balls have been called.
The Probabilities of a Full House
Since bingo is a game ruled by randomness, all players participating in a given session have equal chances of completing Full House patterns with their cards. The reason for this is that both the drawing of the numbers and their distribution on players’ tickets are completely random.
Therefore, in a bingo room with 25 players only, the chances of any of them achieving a full house with one ticket would be 4% but if there are 50 participants, their chances would drop to 2%. Thus, you stand a bigger chance of covering your ticket in full if there are fewer players in the bingo hall. The probability of a Full House increases when fewer numbers remain to be called. It is estimated that in 75-ball bingo, it takes approximately 73 balls to mark off all ticket numbers. The probability of achieving a Full House in 90-ball bingo on the 73rd call is only 3.17%.
