First half betting: lines for the first half only
First half bets settle on the score at halftime. Books set 1H spreads and totals at roughly half of full-game lines, adjusted for how teams start games. Overtime never counts.

First half in four numbers
In short
Key takeaways
- First half lines are not exactly half; books adjust for fast and slow starters.
- Ties at halftime are common, so 1H moneylines often include a three-way option.
- Key numbers change: 3 and 7 matter less in halves than in full games.
- Second half lines are posted at halftime and move fast.

Full-game bet loses
The two bets can win or lose separately.
Quarter and half markets
| Market | Settles on | Common uses |
|---|---|---|
| 1st half | Score at halftime | Teams that start fast |
| 1st quarter | Score after Q1 | Script-driven openings |
| 2nd half | Second-half points only | Live adjustments |
| Team 1H total | One team’s points | Matchup angles |
Most books offer all four on major games.
How books set halves
Books start from full-game numbers and adjust for how teams play early. Some teams score most of their points late, so their 1H lines are smaller.
Totals for halves are often a little more than half, because late-game clock use slows scoring.
Why 1H key numbers differ (NFL)
| Margin | Importance in full game | Importance at half |
|---|---|---|
| 3 | Very high | High |
| 7 | High | Medium |
| 0 (tie) | Rare | Common |
Ties at halftime are common, which changes moneyline value.
Three-way first half moneyline
Because games are often tied at halftime, many books offer a three-way 1H moneyline: Team A, tie or Team B. A two-way 1H moneyline usually refunds bets on a tie.
Check which version you are betting.
Sequence
Betting a first half
Step 01
Find the 1H market
Under game lines or periods.
Step 02
Compare with full-game lines
Is the half priced fairly?
Step 03
Check tie rules
Two-way or three-way?
Step 04
Place before kickoff
Or bet the second half at the break.
Second half betting
At halftime, books post second-half lines in minutes. Prices move quickly as the break goes on.
Second-half bets count only points scored in the second half, plus overtime at many books. Read the rule.

Half terms
Know before you sit
- 1H
- First half.
- 2H
- Second half.
- Three-way
- A market with a tie option.
- Period betting
- Bets on halves or quarters.
Basketball and other sports
In basketball, first-half spreads are often a bit more than half the full-game spread. In hockey and soccer, books often post period or first-half markets with three-way pricing.
Overtime rules still apply: first-half bets never include it.
Common mistakes
- Assuming 1H is exactly half
- Books adjust for how teams start; compare lines carefully.
- Ignoring tie rules
- A two-way 1H moneyline may refund on a tie; a three-way one loses.
- Forgetting overtime rules
- Second half bets may include overtime.
- Chasing at halftime
- Second-half lines move fast; set a plan first.

A bet that settles on the score at halftime, such as a 1H spread, total or moneyline.

Roughly, but books adjust for team styles. A −7 game might be −3.5 or −4 for the first half.

No. First half bets settle at halftime, so overtime is never included. Rules differ between licensed sportsbooks, so read the house rules.
02Markets
What is a three-way first half moneyline?
A bet on Team A, Team B or a tie at halftime. A tie loses two-way bets only if the market is three-way.

Yes, but less. A 3-point margin is still common, while ties are much more common than in full games.

Sometimes, because they get less betting attention. Shopping across books helps.
