I've gone to 6 i believe.

I've gone to 3 sabres games against sj, det, and dal. The SJ one was my 1st one for my birthday and it was the night we traded my favorite player Ryan miller

I'm only 15 and I've been lucky enough to go to 7 Habs games, including a playoff game. Overall they have a 3-4 record in my presence. I also went to some world junior games in Montreal, including the game on December 31, 2014 between Canada and the US, and this year's Russia/USA semi-final

What playoff game did you go to?

Edit: I've never gone to an NHL playoff game for some reason.

I've been to BUF and MTL and I went to a World Cup of Hockey game. No playoff game though.

I went to Montreal vs Ottawa 2013 Game 1. Ottawa won 4-2

I've been to a WCF game in Chicago a couple of first round games in Chi town. However since I go to school in AZ I go to a lot of Yotes games in the cheap seats.

Against who?

WCF against the ducks
Round 1 against the Blues and Nashville
Arizona I'm going to the first three Saturday games this year. I tend to go to a lot of games. Weirdest game I've ever gone to Habs and Stars in Dallas when I went down there to visit a family friend (they knew I liked a Canadian team but they just picked the wrong one). I've also gone to the Leafs Red wings outdoor game in Toronto (which was an absolute blast). I basically just get the cheap seats and move down in Arizona. But I've seen pretty much all 30 teams over the past two years.

against the blues in 2014 or 2016?

Blues in 2016
Nash in 2015

I've been to 3

2007?
Flyers vs Leafs 3-4

2009?
Caps vs Sens 0-2

2011
Bruins vs Bolts 1-6 (Stamkos scored 50 )

ok, what game numbers? you don't need to tell me if you don't want to but you can.

2016 blues 1st home game in Chi Kane took a dumb penalty and the blues scored the winning goal. I thought it was going into overtime before they scored. I remember sitting behind the net on the glass. It was my first game on the glass. If you are all wondering Crawford does look like he talks to himself the entire game.
2015 Nash the Saturday game of that series. 1st home game in chi. I remember vividly because it was my first ever playoff game. It was the intermission where Hossa was left in the box for a couple of minutes after the period ended. I remember Brent Seabrook (he's my favorite player) scored. My dad must have thought I was crazy. The people around me must have thought I was crazy because of how much I cheered.
I remember the WCF in standing room. Shaw had two goals to send the series back to Anaheim. Booing Corey Perry. Chant "Corey Corey Corey". When Crawford made an amazing save.
Honestly I could reminisce all night long about the games I've seen. I've seen Steven Stamkos play and he was amazing. I've seen the capitals get blown out in Arizona last year and I was sitting next to a bunch of caps fans.
