raffle
A game where people buy tickets for a chance to win.
A raffle is a way of giving away a prize by selling numbered tickets and then randomly drawing one winning number. At a school fundraiser, you might buy a raffle ticket for a dollar, hoping your number gets picked to win a new bicycle or a gift basket. The more tickets you buy, the better your chances, but there's no guarantee you'll win.
Raffles work because many people contribute small amounts of money for a chance at something valuable. If 500 people each buy a $2 ticket, that's $1,000 raised, even though the prize might only cost $200. Organizations like schools, churches, and charities use raffles to raise money because people enjoy the excitement of possibly winning.
The drawing itself is meant to be completely random and fair. Someone might pull a ticket from a box while blindfolded, or use a machine that tumbles all the tickets together before selecting one. The randomness is what makes it different from a contest where the best entry wins. In a raffle, luck determines everything.
As a verb, to raffle something (or raffle it off) means to give it away through this method. You might hear that a local business donated a laptop to be raffled off at the school carnival.
