Blackout ( bingo )



A variation of the game of bingo in which the object is to cover all the 25 spaces on your card.
Usually 50 to 60 of the 75 bingo numbers have to be called to cover all the numbers on a card.
But blackouts in as few as 42 or 43 numbers have been recorded in the Seattle area in the past five years.
Blackouts in 48 or 49 numbers, while not frequent, are not uncommon.
