When the Road Team Wins Game 1 of an NHL Playoff Series

The sample runs from 1939 - the first year the NHL used a best-of-seven format in any round - through the spring of 2025. In that 87-year window, 294 best-of-seven series had the road team taking Game 1. Those 294 teams then went 167-127 in winning the series itself.

For comparison: when the home team wins Game 1, they win the series 74.6% of the time (367-125). Same Game 1 win, but 18 percentage points of difference in outcome. Venue still matters enormously, even once the scoreboard is 1-0.

The Baseline Nobody Talks About

To feel the 56.8% properly, you need the number underneath it. Teams that simply start a best-of-seven on the road - without conditioning on what happens in Game 1 - win the series about 33-34% of the time. That is the gravitational pull of home-ice advantage over eight decades of hockey.

Winning Game 1 on the road pulls you from roughly a one-in-three long-shot to a 56.8% favourite. It is a 23-point swing in a single evening. That is why the talking heads get excited. They are just not looking at the right comparison.

Round by Round: Where the Edge Lives

The 56.8% headline hides some interesting round-specific behaviour. The first round - historically the "Prelim" in the WhoWins data, today's Conference Quarterfinals - is the least predictive. A road Game 1 win in the opening round only translates to a series win 52.8% of the time. Essentially a coin flip.

The edge actually grows deeper into the bracket:

Two things jump out. The second and third rounds are where a road Game 1 win is most predictive. By that point in the bracket you have already earned your way through, and beating a higher seed on their ice in Game 1 usually means you are the better team, not just the luckier one on a given night.

The first round is the noisiest. Eight series a year, wildly varying quality gaps, and home-ice decided by points totals that could be a dozen games apart. A road Game 1 win in Round 1 tells you much less than in, say, a Conference Final between two hundred-point teams.

The Game 2 Pivot

If there is one secondary stat that rewires how you watch a playoff series, it is this. When the road team wins Game 1 and then also wins Game 2 - stealing both games on the road and taking a 2-0 series lead back home - they win the series 80.4% of the time (90-22).

When they win Game 1 and drop Game 2, knotting the series at 1-1 heading home? The series win rate collapses to 42.3% (77-105).

Think about what the 42.3% is really saying. A team that won Game 1 on the road - a meaningful accomplishment - is then worse than a coin flip to win the series the moment they drop Game 2. The Game 1 upset gets effectively neutralized by a home-team Game 2 response.

The home team wins Game 2 in these situations 61.9% of the time (182 of 294). The split happens fast. By the end of Game 2, the road team's 56.8% has already forked into an 80.4% favourite on one branch and a 42.3% underdog on the other.

Home Game 1 vs Road Game 1: The Full Picture

Pulling it all together, here is how Game 1 outcomes actually translate into series wins across the NHL's best-of-seven history:

Winning Game 1 at all is worth about 18 percentage points on top of the baseline series win rate of 50/50. But where you win it matters almost as much as the fact that you won it. An 18-point gap between the two Game 1 scenarios is not a small thing - it is essentially the difference between a clear favourite and a slight one.

What the road team needs to do

The math hands you the playbook. If you are a lower-seeded team who just stole Game 1, the second game is existential. Winning it locks in an 80.4% series win rate. Losing it drops you to a 42.3% dog, and now you are defending home ice in Games 3 and 4 against a team that has already shown it can win in your building.

This is why savvy coaches talk about "winning the next shift" after a Game 1 upset rather than celebrating. The win counts, but only if you back it up in Game 2. Otherwise you just had one good night on the road against a better team that remembers how to play.

The Historical Context

The NHL started using best-of-seven playoff series in 1939. The very first one - series 32 in the all-time WhoWins list - was the Boston Bruins over the New York Rangers in a seven-game Semifinal. From there the format has covered most playoff rounds, with occasional exceptions in the 1930s-40s and the NHL's WHA absorption era.

A few historical notes worth knowing:

The modern era - since the NHL's 2013 realignment into the current 16-team, four-round format - has been particularly friendly to road Game 1 winners. The 2023 first round alone saw visitors go 31-19 across the eight series, an NHL record for road wins in a single round. Six of the eight first-round series that year clinched on the road.

Whether that pattern is durable or a coaching-style artifact is its own question. What is not in doubt is the 87-year baseline: winning Game 1 on the road is real. It just is not what the broadcast graphics want you to believe it is.

The quick takeaway

56.8% to win the series. 80.4% if you also win Game 2. 42.3% if you do not. Everything else is broadcaster theatre.
