BSBingo is the perfect "corporate productivity" tool for staying conscious during meetings you'd otherwise fall asleep in.
Every time someone uses one of the words in the lefthand BSBingo list, you select it. The word fills in a square on the bingo board. You get Bingo by filling in five squares across, down or diagonally.
Stand up and yell, "Bingo!" Sure to impress the boss.
