Ipswich Town became the first away team to win at Bloomfield Road this season, after Daryl Murphy's last minute header settled a remarkable game which wasn't for the weak hearted.
Steve Davies thought he had earned Blackpool a point with a last minute strike of his own, but Murphy's untidy header settled the game in Ipswich's favour.
Stephen Dobbie had The Seasiders on course for victory after heading home the opener, but Frank Nouble and Paul Taylor put The Tractor Boys ahead, before the late drama.
Blackpool made one change to the side that beat Nottingham Forest, with Bobby Grant replacing Tyler Blackett in the starting line-up.
It was the hosts who had the first chance of the game, when Dobbie broke down the right and squared for Ricardo Fuller to shoot via the ground into Dean Gerken's hands.
For the following 15 minutes Fuller's effort remained the only shot on goal, as Blackpool controlled an opening of few chances.
Ipswich, like Blackpool, were being restricted to half chances, with David McGoldrick's drilled cross evading everyone in the centre.
However the visitors had a golden chance to take the lead moments later, as McGoldrick's effort was blocked as far as Ryan Tunnicliffe, but the midfielder's shot from inside the box was deflected wide for a corner.
Town were made to rue that missed chance minutes later as well, as internet sensation Dobbie brilliantly headed Grant's whipped cross past Gerken to put The Seasiders ahead.
That meant Dobbie has scored in successive week for Pool, and the man who provided the assist, Grant, almost turned goal scorer next, but the winger's powerful effort was sensationally kept out one-handed by Gerken.
Dan Gosling was next to try his luck, but his effort whistled wide after Fuller had bullied his was through the Ipswich defence.
For Ipswich, McGoldrick fired a free-kick off target, as Blackpool went in for the break on top.
The visitors came out of the traps quickly for the second half. Substitute Nouble won a corner which was headed straight at Matt Gilks by Daryl Murphy.
Despite that chance, Blackpool remained the bigger threat, and Thomas Ince came close when his shot was blocked, following good work by Gosling down the left.
From the resulting corner Broadfoot headed over, but was also penalised for a push in the build-up.
At the other end Murphy again squandered a good chance, volleying wide at the back post after being set up by Carlos Edwards.
With their next attack The Tractor Boys leveled however, as McGoldrick surged forward and set up Nouble - the former-West Ham man side stepped a challenge, before firing underneath Gilks to restore parity.
Nouble now had the bit between his teeth, and may well have scored again had it not been for a last-ditch tackle from Gary MacKenzie.
With the game perfectly poised, Gosling tried to drag Blackpool back ahead, but bent his effort from the edge of the box narrowly wide.
Davies and Nathan Tyson were then brought off the bench in another attempt to claim all three points, with Fuller and Grant making way.
However the visitors were next to strike, going ahead with five minutes remaining. Another substitute Paul Taylor tried his luck from the edge of the box, and with Gilks rooted to the spot it nested into the bottom corner.
That goal set up a grandstand finish, as Tyson had an effort deflected behind for a corner.
And as the board for stoppage time went up Blackpool hauled themselves level, as Davies hammered home the equaliser past Gerken.
The final few moments certainly were not for the weak hearted, as Stephen Hunt's drive was headed over by MacKenzie.
Somehow the drama wasn't over however, and from the resulting corner Murphy's header snuck under Gilks to remarkably earn the visitors all three points at the death.
