Key Takeaways
- NFL regular-season overtime is a 10-minute sudden-death period with a modified scoring rule on the opening drive.
- NBA overtime consists of five-minute extra periods repeated until a winner is decided — no sudden death.
- NHL regular-season overtime uses a 5-minute 3-on-3 period, followed by a shootout if still tied.
- MLB plays unlimited extra innings with a runner-on-second rule in effect starting in 2020.
- Playoff overtime formats are often stricter and longer than their regular-season counterparts.
Our Verdict
No two major American sports handle overtime the same way, reflecting each league's priorities around entertainment, player safety, and competitive integrity. The NBA's repeated five-minute periods are the most straightforward, while the NHL's shootout remains the most polarizing. The NFL's modified sudden-death rules and MLB's runner-on-second format represent deliberate compromises between drama and practicality.

NFL: Modified Sudden Death
The NFL's overtime format has evolved considerably. In the regular season, teams play a single 10-minute overtime period. The first team to score wins — but with one critical caveat: if the team that receives the opening kickoff scores only a field goal on its first possession, the opposing team gets a chance to respond. A touchdown on the opening drive ends the game immediately. If neither team scores during the period, the game ends in a tie — a result that counts in the standings.
The playoffs use a different standard. Since the 2022 postseason, both teams are guaranteed at least one possession in overtime regardless of what happens on the opening drive. If the game remains tied after each team has had a possession, true sudden death takes over.

NBA: Repeated Five-Minute Periods
The NBA takes the simplest philosophical approach: keep playing regular basketball. When regulation ends tied, teams play a five-minute overtime period. If still tied, they play another, and another, for as many periods as needed. There is no sudden death, no shootout, and no format change between regular season and playoffs.
Player fatigue and foul management become critical factors in extended overtime games — coaches must balance using their best players against the risk of fouling out. The NBA's approach is the most consistent across the entire season, which makes it easy to follow even when you're tracking multiple leagues at once. The guide to following multiple sports seasons covers strategies for keeping up with overlapping schedules.
| NFL | NBA | NHL | MLB | |
|---|---|---|---|---|
| Regular-season length | 10 minutes | 5-minute periods | 5 minutes (3-on-3) | Unlimited innings |
| Sudden death? | Yes (modified) | No | Yes (OT period) | No |
| Tiebreaker mechanism | Tie stands | Keep playing | Shootout | Runner on 2nd base |
| Playoff format differs? | Yes — both teams get possession | No change | Yes — no shootout | No change |
| Playoff periods/format | Full 10-min periods, sudden death | Repeated 5-min periods | Full 20-min sudden-death periods | Same runner-on-second rule |
NHL: 3-on-3 Overtime and the Shootout
The NHL's regular-season format is designed for fast, open play. After a 60-minute regulation tie, teams play a five-minute 3-on-3 sudden-death period — three skaters per side instead of the usual five. The reduced ice coverage creates more open lanes and makes scoring significantly more likely. If no one scores in that window, the game goes to a penalty shootout: three players per side take alternating penalty shots, with sudden death continuing in rounds if still tied after three each.
Playoff hockey is a different beast entirely. There is no shootout in the postseason — teams play full 20-minute sudden-death periods until someone scores, no matter how many it takes. Historic playoff games have stretched to multiple overtimes, producing some of the most memorable moments in sports history. The NHL's points system is directly tied to these formats — a regulation win earns more value than an overtime or shootout win. The NHL points system explainer breaks down exactly why that distinction matters for playoff positioning.
Shootout Controversy in Hockey
The NHL shootout remains one of the most debated rules in American sports. Critics argue that a skills competition — individual skaters against a goalie — is a poor way to decide a team game. Proponents point to the entertainment value and the fact that the regular-season point system partially cushions the impact of a shootout loss. This debate is worth keeping in mind when comparing the NHL's format to other leagues.
MLB: Extra Innings With a Runner on Second
Baseball's extra innings are conceptually simple — keep playing full innings — but the modern game added a significant twist starting in 2020. Each extra inning now begins with a runner placed on second base (the player who recorded the final out in the previous half-inning). This "free runner" rule was introduced to shorten game lengths and reduce pitcher workloads in extended contests.
There is no sudden death in the traditional sense; each team still gets a full half-inning to score. Both regular season and postseason games use this format, making MLB one of the more consistent leagues in that regard. It's worth noting how extra innings interact with MLB tiebreaker rules when teams finish with identical regular-season records — those are separate procedures from extra-inning gameplay.

NHL OT games decided in regulation OT (not shootout)
Historically, a significant portion of NHL regular-season overtime games are resolved before reaching the shootout, reflecting the open nature of 3-on-3 play.

How Overtime Affects Standings and Strategy
Overtime formats aren't just rules — they shape team strategy and standings in meaningful ways. In the NHL, losing in overtime or a shootout still earns a team one point in the standings, which is why coaches sometimes play conservatively in the final minutes of regulation to avoid a loss. The guide to how standings differ across sports explores how these nuances affect playoff races.
In the NFL, a tie carries playoff seeding implications that can ripple through an entire conference. In the NBA, extra overtime periods can meaningfully alter rest schedules and rotation decisions heading into the next game. Understanding overtime isn't just trivia — it's a window into each league's values and competitive design.
Quick Reference for Casual Fans
If you're watching a sport for the first time and a game goes to overtime, here's the shorthand: NBA means more basketball, NHL regular season means a shootout is coming if 3-on-3 doesn't decide it, NFL means one big possession could end it, and MLB means extra innings with a runner already in scoring position. Each format is designed to be exciting — just in very different ways.
