In the final minutes, Skellefteå played with six outfield players against five with a chosen goalkeeper.
Skellefteå also took a timeout to try to keep the streak alive.
With three seconds left, Ahti Oksanen instead put 3-1 into an empty cage from close range.
The audience stood and jumped for joy.
- It's a bit unfair.
I think we fight well but can't get the puck in.
The game swung when they scored two in the second period.
The talk about the record was nothing negative for us, we played a good match, says Skellefteå's Pär Lindholm to C More.
In 93 seconds in the second period, Oskarshamn turned the game around.
After Johan Johnsson's backhand for 1-1, the home team had to play in the power play, which has the very best statistics in the SHL.
Antti Suomela fished up the puck behind the goal and quickly sent in 2-1 and further improved Oskarshamn's power play statistics.
- I got the puck on my calf and it bounced forward well, says Johnsson about his goal.
Skellefteå took the lead in the middle of the first period.
Oskarshamn had established play in SAIK's zone and the German Tom Kühnhackl bumped into the blue and twisted the puck with him in a free position.
Alone with Tim Juel, he found a gap and gave Skellefteå the lead with 1-0.
- I was a little surprised when I got the situation, got a lucky bounce and was also lucky when I got the puck in, says Kühnhackl.
Skellefteå's record goalkeeper Linus Söderström, kept a clean sheet for 217 minutes, was absent again due to illness.
18-year-old Alexander Hellnemo, who stood against HV71 last time, was again trusted between the posts.
Counted over two seasons and also playoffs, Färjestad has the record with 17 straight victories.
