Bingo needs a group and one host. Everyone else gets a card with numbers under the letters B, I, N, G, and O. The host pulls the balls one at a time and calls out the letter and the number, and you cover it with a chip if it’s on your card. You can also mark the called numbers on the big game board, so nobody loses track. Whoever completes the winning pattern first shouts “Bingo!” and wins. But which Bingo rules you play by is up to you: a row, the four corners, or the whole card. There are lots of ways to play, so agree before you start.
