Questions

What is Propper?

Propper is a free player prop research tool and parlay builder for NBA, NFL, NHL, and MLB. It shows how often a player has cleared a line, how tonight's matchup looks, and it can build a full parlay in one tap.

Is Propper free?

Yes. Propper is free to use and you do not need an account to roll a parlay, research a player, or track a slip.

Does Propper take bets?

No. Propper does not take bets or hold money. You research and build your slip here, then place it yourself at a licensed sportsbook if you choose to.

How does the parlay roll work?

Pick a payout target such as 5x, then tap Roll. Propper checks each player's hit rate, the matchup, and tonight's posted lines, and deals a set of legs that fits the target. Lock the legs you like and reroll the rest.

What is a hit rate in prop betting?

A hit rate is how often a player has gone over or under a line in past games. Propper shows it as games hit of games played, for example 8 of the last 10, so the sample size is always visible.

Which sports and props does Propper cover?

Propper covers player props for the NBA, NFL, NHL, and MLB, including points, rebounds, assists, threes, passing and rushing yards, shots on goal, hits, and more.

Can Propper guarantee a winning parlay?

No tool can. Propper shows the numbers behind each pick so you can make a more informed choice, but every bet can lose. Only bet what you can afford to lose.
