"Cow patty bingo” (also called “cow chip bingo,” “cowpie bingo,” bovine bingo,” “bossy bingo,” “fertilizer lottery,” “cow pat lottery,” and surely many other names) is when squares are made on a field; the numbered squares are sold, a cow is let loose, and the person holding the numbered square with the greatest amount of cow droppings wins. The game is often played in rural areas to benefit a local charity. However, the game can be rigged by adding a special scent to a square.
“Cow patty bingo” was recorded in Kansas in March 1984, “bovine bingo” was held in Pierz, Minnesota in 1985, and “cow chip bingo” is recorded in Uvalde, Texas from 1987. The origin of the bingo game is unknown.
A similar game popular in Texas bars is “chicken bingo.”
Wikipedia: Bovine bingo
Bovine bingo is a traditional rural fundraising game that is often played at country fetes and summer fairs, usually for fundraising purposes.
Bovine bingo is not really a form of bingo, but a form of lottery. The game is set up by marking out a grid of rectangles on an enclosed land area, such as a paddock or farm field. This is usually done by chalking lines. The grid cells are then numbered or otherwise identified in some way, and chances are sold on each cell. A cow (or other livestock animal) is then let loose within the enclosure. Where the first “cowflop” (defecation) lands determines the winner. Another popular variation of this game takes place during parades, usually with horses. Same rules apply, however.
The game is sometimes controversial because of the stress the animal may be exposed to.
The game is also known as “Cow Chip Bingo”, “Cowpie Bingo”, “Fertilizer Lottery”, “Cow Patty Bingo”, “Cow Pat Lottery”, or “Bossy Bingo.”

You might call it “Bovine Bingo.” Whatever you call it, it was perhaps the most unusual fund-raiser of the year in Kentucky. It happened in Hardin County on Friday night. At West Hardin High School’s homecoming football game, the local Athletic Boosters Club showed that when the chips are down, money can be raised. The club did it with a remarkable raffle. After the game, the football field was sectioned into 144 numbered squares of about three feet…

HUNTSVILLE, Texas (AP)—A junior farmer group is using the call of nature in hopes of spicing up a bingo game.
It’s Cow Patty Bingo, says Pam Markham, president of the Huntsville Ag Booster Club.
The county fairgrounds arena will be divided into large numbered squares that gamblers can buy for $2 to $10. The winner—who will pocket up to $500—will be holder of the square that contains the largest cow patty.
“Hopefully, the cows will feel the urge to let the chips fall,” Markham says.
Next month’s game is intended to raise money for equipment for the agriculture club.
In case of a tie, the evidence left on the bingo square will be weighed.

I have never heard of an official name for the game. Some call it cow chip bingo, some call it bull(bleep) bingo. Whatever you call it, it is an unusual and funny way to “pile” up some cash for a team.

There are few treats sprinkled along the journalistic path as funny as the writer’s dilemma of describing exactly what “kowchip bingo” is.
Known in other communities as “bossy bingo,” “bovine bingo,” “cowpie bingo,” “fetilizer lotto,” or “cow pat lottery,” cow chip bingo involves volunteers making a grid on a field, selling “deeds” to the resulting squares and rewarding the owners of said properties when a cow makes a deposit on the land in their square.
