Parimutuel gambling is when people bet on horse or dog races. Imagine a big playground with a track in the middle where horses or dogs run around. There are special places where people can watch the races, and some of them want to bet on which animal they think will finish first.
In parimutuel gambling, all the bets are collected together in a big pot, and this pot is divided among all the winners. This means that if many people place bets on a single animal and that animal wins, each person will get just a little bit of money. But if only a few people bet on a specific animal and that animal wins, those people will get a lot of money.
The odds of each animal winning are based on how much money is being bet on them. If a lot of people are betting on one animal, that animal's odds of winning will be lower because the pot is divided among more people. However, if few people are betting on another animal, that animal's odds of winning will be higher because there are fewer people to share the pot with.
In the end, everyone who placed a winning bet will get their share of the pot, and the people who placed losing bets will lose their money. Parimutuel gambling is a fun way to enjoy horse or dog races while also having a chance to win some money.
