Coverall Jackpot is a term that refers to the top prize available in a game of 75 ball pattern bingo, and one which is won by covering all of the available squares of the bingo ticket. It could therefore be viewed as the 75 ball bingo version of a full house. Because the coverall pattern requires the player to cover all of the squares on the bingo ticket, it is sometimes also referred to as a “blackout” pattern.

75 ball bingo games are played on tickets that show a five by five grid of numbers, giving twenty-five squares in all. In many games, the central square of the grid is given as a “free number” which means that it does not need to be marked, but this rule does vary from place to place so it is important that you check before playing.

Most 75 ball games require players to make patterns on their bingo tickets in order to win a prize, and for this reason the game is also referred to as “pattern bingo”. There are scores of different patterns that are played all over the world, and these range from simple geometric patterns such as a square or circle and letters of the alphabet right through to shapes with names like “picnic table” and “coffee cup”. It is worth noting that there is, among these, a pattern known as the “open house” which is much the same as a coverall but with one unmarked square.

In some bingo games, a progressive coverall jackpot is on offer in addition to the regular coverall jackpot. The progressive jackpot increases in value from game to game until someone eventually wins the whole sum (or shares it if there is more than one eventual winner). To win such a progressive, a coverall pattern must be achieved before a certain quantity of bingo numbers have been called.
