Prop betting,
in plain words

The terms you'll see in the app and at any sportsbook.

Player prop
A bet on one player's stat line, such as points, rebounds, or passing yards, instead of the final score.
Line
The number the sportsbook sets. You bet on whether the player finishes over or under it.
Over and under
The two sides of a prop. Over 24.5 points wins at 25 or more. Under wins at 24 or fewer.
Hit rate
How often a player has cleared a line in past games. Eight of the last ten is an 80 percent hit rate.
Parlay
Several bets tied into one. The payout multiplies with each leg, and every leg has to hit.
Same game parlay
A parlay where every leg comes from a single game.
Implied probability
The chance a sportsbook's price suggests. A price of -150 implies 60 percent.
Expected value
What a bet returns on average over many tries. A positive number means the price is better than the true odds.
