You’re sitting in a cold arena or maybe just on your couch with a bag of chips. Suddenly, a whistle blows. A player in a bright jersey looks frustrated, skates toward a small glass box, and sits down. The announcer shouts something about a penalty. The vibe in the rink shifts instantly.
That’s it. You’re about to see a power play.
Honestly, if you don’t understand this specific mechanic, hockey just looks like a bunch of guys chasing a rubber disk at 30 miles per hour. But the power play is where the strategy actually gets interesting. It is the ultimate "make or break" moment in a game.
So, what is a power play exactly?
At its most basic level, a power play happens when one team commits a foul and gets sent to the penalty box, leaving their team shorthanded. Most of the time, hockey is played "five-on-five." When a player gets a minor penalty—maybe they tripped someone or got a bit too reckless with their stick—they have to sit out for two minutes.
Now the other team has five skaters against four.
That advantage is the power play. It’s a numbers game. Imagine trying to guard a room with four people when five people are trying to get in. Someone is always going to be open. That’s the entire goal. The team with the extra man (the "man advantage") spends two minutes trying to exploit that gap to score.

It isn't always a two-minute minor, though. If things get violent or dangerous, officials hand out a five-minute major. During a minor penalty, if the power play team scores, the penalty ends immediately. The player hops out of the box, and everyone goes back to full strength. But a major? That’s different. Even if the team scores three goals in a row, the penalized player stays in the box for the full five minutes. It can be a total blowout.
The Chess Match on Ice
You’ll notice the team on the power play doesn’t just rush the net like a chaotic mob. They set up. They use specific formations because, surprisingly, having an extra person doesn’t guarantee a goal. In fact, most NHL power plays only convert about 20% of the time.
The most common setup you’ll see is the Umbrella. One guy stays high near the blue line (the point), two guys stay on the "half-wall" (the sides), and two others hover near the net. It looks like an umbrella. They pass the puck back and forth, trying to pull the defenders out of position.
Why? Because they want a "one-timer."
That’s when a player hits the puck immediately as it reaches them without stopping it first. It’s fast. It’s hard to track. It’s the primary weapon for guys like Alex Ovechkin, who has made a career out of sitting in the "Ovi Spot" (the left faceoff circle) and blasting pucks into the net during power plays.

The Penalty Kill: The Underdog’s Game
We can't talk about the power play without talking about the "Penalty Kill" (PK). These are the four guys trying to survive. They aren't trying to score—though if they do, it's called a shorthanded goal, and it’s basically the most embarrassing thing that can happen to the other team.
The PK unit usually forms a "Box." They stay tight in the middle of the ice, blocking shots and clogging up passing lanes. Their only job is to kill time. They want to get the puck and launch it all the way down the ice to the other end. In hockey, normally you can't do that (it's called "icing"), but when you're shorthanded, the rules change. You are allowed to wing that puck as far as you want.
Why the Rules Actually Matter
There are layers to this. Sometimes you get a "five-on-three." This happens if a second player on the same team gets a penalty before the first one is over. If you can't score with a two-man advantage, your fans might actually start booing. It is almost a guaranteed goal if the team is halfway decent.
Then there is the "four-on-four." This happens when both teams get a penalty at the exact same time. It’s not a power play for anyone. Instead, there’s just more open ice. The game gets faster. The superstars love four-on-four because they have room to breathe and show off their skating.
Real-World Impact: The 2019 Playoffs
If you want to see how a power play changes history, look at Game 7 between the Vegas Golden Knights and the San Jose Sharks in 2019. Vegas was winning 3-0 with about ten minutes left. A Vegas player got a five-minute major penalty for a cross-check.

In those five minutes, San Jose didn't just score once. They scored four times.
They turned a 3-0 certain loss into a 4-3 lead during a single power play. It is widely considered one of the most insane moments in sports history. That is the power of the man advantage. It can erase sixty minutes of hard work in a heartbeat.
Common Misconceptions
People often think the goalie is part of the "five" count. He’s not. It’s five skaters plus a goalie. Also, people think you can have as many penalties as you want. Technically, you can, but a team can never have fewer than three skaters on the ice. If a third person gets a penalty, their time doesn't start until one of the first two penalties expires.
Another weird one? The "offsetting penalty." If two guys get into a fight, they both go to the box, but the teams stay at five-on-five. The players just sit there and think about what they did for five minutes while the game continues as normal.
Actionable Strategy for Watching
Next time you’re watching a game and a power play starts, stop following the puck for a second. Look at the players without it.
- Watch the "Bumper": This is the guy standing right in the middle of the defensive box. He’s the most dangerous player because he’s always open for a split-second.
- Check the Goalie’s Vision: See if a player is standing right in front of the goalie. This is called "screening." If the goalie can't see the puck, he can't stop it. The power play team will always have one "big body" whose only job is to be a human curtain.
- Listen to the Crowd: If the power play team is passing too much without shooting, you’ll hear the fans scream "SHOOT!" It’s a universal hockey tradition.
Understanding the power play changes how you view the flow of a game. It stops being a random scramble and starts being a high-pressure tactical battle. You start to see the lanes opening up, the defenders getting tired, and the exact moment a team decides to go for the kill.
Pay attention to the "Power Play Percentage" (PP%) on the screen. A top-tier team usually hovers around 25%. If a team is struggling at 10-12%, they are likely over-passing or failing to get "traffic" in front of the net. Watching how a coach adjusts their "units"—putting different combinations of players on the ice—tells you everything you need to know about their desperation level in that moment.
