A record 26 million Americans are expected to bet $6.8 billion on Super Bowl LIV, as more states legalize online gambling and the public becomes comfortable with it, according to newly released data from the American Gaming Association.

As gamblers increasingly want more ways to bet on the game, oddsmakers are increasingly happy to oblige them.

Officially known as a "proposition bet" or a side bet, prop bets are placed either before or during a game. Think of it as a way to make a little extra money and hedge around the main bet.

Prop bets have grown more popular over the years, with an increasing number of gamblers looking at placing a wager on the total number of points scored (over/under), the length of the national anthem or who scores the first touchdown.
