Some were close games, others were not, while one set a record that stands to this day. All of them were painful, and although time heals all wounds, they still hurt if you think about them long enough.
Aug. 31, 1997: Jets 41, Seahawks 3
Seattle gets buried in its season opener at the Kingdome. Todd Peterson's 31-yard field goal in the third quarter are the only points Seattle can muster while giving up 434 total yards.
Dec. 31, 1988: 1989 Bengals 21, Seahawks 13
The Seahawks close to within one possession at Cincinnati on separate scoring rushes by John L. Williams and Dave Krieg. Norm Johnson misses the extra point after Krieg's TD, however, leaving Seattle down by eight in the days before the two-point conversion. The Bengals hold on and the Seahawks do not play in another postseason contest for more than 10 years.
Dec. 23, 1989: Redskins 29, Seahawks 0
The Seahawks finish 7-9 and out of the playoff picture in being shut out by Washington, but this one is more notable for the fact that it was the final game in the career of Hall of Famer Steve Largent. The NFL's all-time leading receiver as he hangs up his cleats, he finishes with two catches for 41 yards at the Kingdome, and retires with 819 receptions for 13,089 yards and 100 touchdowns.
Jan. 9, 2000: Dolphins 20, Seahawks 17

The Seahawks fall in their final home game and the final event ever at their inaugural stadium, which is imploded two months later on live TV. It also marks Seattle's final playoff game as a member of the AFC, as the Seahawks return to the NFC West in 2002.
The Seahawks take a 17-10 lead in the third quarter following Charlie Rogers' 85-yard kickoff return, but the Dolphins pull within four points on a 50-yard field goal, and then score the winning touchdown from two yards out with less than five minutes remaining in regulation.
Seattle manages just 171 yards of total offense while closing out the Kingdome era with a 103-84 overall record.
Nov. 4, 1979: Rams 24, Seahawks 0

The Seahawks compile minus-seven yards of total offense in a loss to Los Angeles at the Kingdome.
That ignominious single-game mark still stands as an NFL record more than 35 years later.
Jan. 3, 1987: Oilers 23, Seahawks 20 (OT)
Steve Largent ties the game in the fourth quarter on a 12-yard pass from Dave Krieg, but Tony Zendejas' 42-yard field goal in sudden death ends the Seahawks' season at the Astrodome. The Seahawks force a turnover at a key point, but it's called back.
Largent catches seven passes for 132 yards and Krieg is 16-of-38 for 237 yards and two scores, although Seattle manages just 29 yards on the ground.
Nov. 27, 1980: Cowboys 51, Seahawks 7
Talk about your Thanksgiving Day massacre.
The Seahawks' season-ending nine-game tailspin continues as they are pummeled by the Cowboys, with Jim Zorn's two-yard scoring toss to Ron Essink in the fourth quarter the only play preventing Seattle from being shut out.
Dallas racks up 325 total yards before a national TV audience, including 200 yards rushing, and also forces seven Seattle turnovers.
Six years later to the day, the Seahawks enact some revenge with a 31-14 win at Texas Stadium, also on Thanksgiving.
Dec. 29, 1984: Dolphins 31, Seahawks 10
A year after Seattle edged host Miami to advance to the AFC Championship Game, the Dolphins return the favor to the Seahawks at the Orange Bowl.
Dan Marino and company break open a 14-10 halftime lead with 17 unanswered points in the second half to send Miami to the title game against the New York Jets, while the Seahawks end their campaign with a then-best-ever 13-5 mark.
Dave Krieg goes 20-of-35 for 234 yards and a 56-yard touchdown pass to Steve Largent, who finishes with six catches for 128 yards. The Dolphins roll up 405 total yards of offense while limiting the Seahawks to just 51 yards rushing, a year after Miami surrendered 151 yards on the ground to Seattle.

After winning the overtime coin toss at Lambeau Field, Matt Hasselbeck (in)famously boasts that the Seahawks will take the ball and score, according to Seahawks.com..
Hasselbeck, who finishes 25-of-45 for 305 yards, does complete a touchdown pass in the extra session—unfortunately, it's to Green Bay's Al Harris, who returns the ball 52 yards for the winning pick-six.
Shaun Alexander has just 45 yards rushing, but scores from one yard out with 51 seconds remaining in regulation to tie the game. That sends it into the ill-fated OT, where the Seahawks' playoff drought reaches five losses and 19 years.
Jan. 13, 2012: Falcons 30, Seahawks 28

Down 20-0 at the half, and then 27-7 after the third quarter, the Seahawks nonetheless rebound to take a 28-27 lead with 31 seconds remaining in regulation on a two-yard run by Marshawn Lynch.
Seattle doesn't get to punch its ticket to San Francisco for the NFC Championship Game, though, as the Falcons manage to get close enough for Matt Bryant to kick a 49-yard field goal just 23 seconds later and oust the Seahawks from the playoff picture.
Russell Wilson completes 24 of 36 passes for 385 yards and two touchdowns for the Seahawks, while adding a team-high 60 yards rushing and scoring once on the ground.
Jan. 9, 1984: Raiders 30, Seahawks 14
The Seahawks are 60 minutes away from their first Super Bowl berth, but it might as well be 60 years.
The Raiders roll out to a 20-0 halftime lead, hold the ball for nearly 38 minutes, and rack up 401 yards of total offense on the afternoon, ending Cinderella Seattle's title hopes, after two Seahawks' regular-season victories over Los Angeles that same season.
Dave Krieg completes just three of nine passes with three interceptions before giving way to Jim Zorn, who goes 14-of-27 for 132 yards, two touchdowns and two picks. Seattle gains just 65 yards rushing in failing to come back, but gets a measure of revenge later that year when it eliminates the defending champion Raiders at the Kingdome in a first-round playoff contest.
Feb. 5, 2006: Super Bowl XL: Steelers 21, Seahawks 10
ELAINE THOMPSON/Associated Press
The Seahawks give up three big offensive plays to go along with questionable officiating calls and their own poor clock management to see their Super Bowl dreams go down the drain in Detroit.
Matt Hasselbeck goes 26-of-49 for 273 yards, a touchdown and an interception, while Shaun Alexander rushes for 95 yards in front of a pro-Pittsburgh crowd.
The Seahawks only turn the ball over once, but finish just 5-of-17 on third down in falling at Ford Field.
Feb. 2, 2015: Super Bowl XLIX: Patriots 28, Seahawks 24
USA TODAY Sports
The Seahawks come up one yard shy of repeating as NFL champions when Malcolm Butler intercepts Russell Wilson at the goal line with 26 seconds left on the clock in Arizona.
After trailing early on, Seattle comes back twice to tie things up at the half, and takes a 24-14 lead after 45 minutes. The Patriots then score 14 unanswered points in the fourth quarter, although Seattle gets one last chance after Jermaine Kearse's late juggling catch puts them near the New England end zone. Two plays later, Butler's pick on a slant seals Seattle's fate.
Marshawn Lynch rushes for 102 yards and scores a touchdown, but doesn't get a shot at a second score on 2nd-and-goal with time winding down, as the Seahawks come up just short of a second straight Super Bowl title.
