A parlay is a type of bet where you pick more than one outcome for different events. Let's say you want to bet on three football games: Game 1, Game 2, and Game 3. You think that the home team will win in Game 1, the away team will win in Game 2, and it will be a tie in Game 3.
To make a parlay bet, you need to put all three picks in one single bet. If all three of your picks come true, you win the bet and get a bigger payout than if you had made three separate bets. But if any of your picks are wrong, then you lose the entire bet.
It's like playing a game where you need to get three things right in a row, and if you do, you get a big prize. But if you get one thing wrong, you don't get anything. It's a riskier bet but with a higher payout. So be sure to choose carefully!
