Coverall, or blackout bingo, is one of the most popular games among players. Both land based bingo halls and online bingo sites offer coverall bingo games. The simplicity of coverall bingo is responsible for the games popularity among players. Coverall games are usually 75 ball games that require players to fill in all the squares on a bingo card to win. The 90- ball bingo equivalent is called a 'full house.' 75 ball bingo cards have five rows and five columns so players must cover 25 card squares to win a coverall bingo jackpot.
In most coverall games the 'free square' in the center of the card is considered 'marked' so it is not necessary for players to cover the free square in some coverall games. In other games players may be required to cover the free square. Players should always check the rules of any coverall game before playing. Coverall games usually feature larger jackpots than regular bingo games and at many bingo halls coverall games are the last games of the evening. Since coverall jackpots are larger than usual the games are played less frequently.
Some coverall bingo games have progressive jackpots. Progressive jackpots are pots that grow with every game played until there is a winner. Usually progressive coverall games require players to cover all the squares within a certain number of calls. Many online bingo sites host similar games like at InterstatesPoker and the size of the jackpot is determined by the number of calls it takes to cover the card. For example a game may have a jackpot of $5,000 if a player manages to get a coverall within 48 calls and with every call after 48 the jackpot decreases. Some bingo halls offer a variation called odds or evens. The bingo caller calls out the first number of the coverall game. If the number is even players must fill in the spaces of all even numbers to win. If the number is odd the game proceeds as a regular coverall game.
30 ball bingo games are also known as 'speed bingo.' The coverall pattern is the only pattern available in 30 ball bingo. 30 ball bingo cards only have nine numbers to cover and there are only 30 numbers used in the game so the games are very fast. In 30 ball bingo a coverall is referred to as a 'full house.' Speed bingo games are found at several online bingo sites. Coverall games offer players fun, excitement and huge jackpots.
