NBA threes props: over or under made three-pointers
A three-pointers prop asks whether one player makes more or fewer threes than a line set by the sportsbook, such as 2.5. Only made threes count, and attempts that miss add nothing.

Example threes lines
| Player role | Line | Over | Under |
|---|---|---|---|
| Top volume shooter | 3.5 | -110 | -110 |
| Starting wing | 2.5 | -125 | +105 |
| Stretch big | 1.5 | -140 | +115 |
| Bench shooter | 1.5 | +105 | -125 |
| Rookie guard | 0.5 | -200 | +160 |
Made-up prices for illustration; every sportsbook sets its own.
How the line is set
Books start from expected attempts times expected accuracy. A player who takes 8 threes a game and makes 37% of them projects to about 3 made threes.
Because the numbers are small, the line is usually 1.5, 2.5 or 3.5, and the price does the rest. An over 2.5 at -140 means the book thinks 3 or more is likely.
Injuries to teammates, the opponent’s defense on the perimeter and the expected pace all move the line or the price before tip-off.
Attempts and chance of 3 or more makes
| Attempts | 33% | 37% | 40% |
|---|---|---|---|
| 6 | 31% | 39% | 46% |
| 8 | 52% | 62% | 68% |
| 10 | 69% | 78% | 83% |
| 12 | 82% | 88% | 92% |
Our own binomial estimates, before any margin.
Why threes swing so much
Shooting is streaky over small samples. A 37% shooter can go 1 for 9 one night and 6 for 10 the next with no real change in skill.
That variance is why threes props often carry juiced prices and why many bettors prefer alternate lines, such as 4+ threes at plus money.
Volume is steadier than accuracy. A player whose role guarantees 9 or 10 attempts gives you more stable results than one who takes 5 good looks.

Rules and settlement
Like other player props, the bet is usually void if the player does not take the floor. Once he plays, it stands even if he leaves early.
Overtime threes normally count. A three made on a foul still counts as one made three, while the extra free throw adds nothing to this prop.
Settlement uses the official box score. Stat corrections after the game are usually ignored once the bet has been graded.

Know before you sit

- Alt line
- A higher or lower line at a new price.
- Ladder
- Several alt lines on one player.
A worked example
A wing has an over 2.5 threes line at -130. That price implies a 56.5% chance he makes 3 or more. He averages 8 attempts and shoots 37% from deep.
Our simple binomial model gives about a 62% chance of 3 or more makes with 8 attempts at 37%. That gap of about five points is the edge a bettor would look for.
A $13 bet at -130 returns $23 if he hits three threes, a profit of $10. If his coach cuts his minutes in a blowout and he takes only 5 shots, his chance falls below 40%.
Common mistakes

- Shooting is streaky.
- Ignoring attempts
- Volume drives makes.
- Overpaying juice
- -150 needs 60% wins.

Questions before and after you play
A 90-second guide cannot cover every table moment. Tap a group, then a question — answers are short paragraphs, not one-liners.
01Basics
What is a three-pointers made prop?
A bet on whether a player makes more or fewer threes than the line the sportsbook sets for that game.
Do missed threes count?
No. Only made three-point shots count toward the total, so attempts that miss add nothing to the over.
Why is the price often not -110?
Lines on small counts stay at whole-number steps, so the book moves the price instead of the line.
02Rules
What if the player does not play?
The bet is usually void and the stake is returned if the player never enters the game that day.
Does overtime count?
At most sportsbooks overtime threes count toward the total, but check the posted house rules for each book.
Does a four-point play count twice?
No. It counts as one made three; the free throw is not part of a threes prop. Rules differ between licensed sportsbooks, so read the house rules.
03Strategy
Are alternate threes lines good value?
Sometimes. Plus-money ladders can pay well, but the book’s margin is often larger on alternate lines.
What matters more, attempts or accuracy?
Attempts. Accuracy swings a lot game to game, while a player’s role and attempts are steadier.
