Premier League - Rovers deny Blackpool at death
Charlie Adam had scored twice in four first-half minutes - drilling home a controversial penalty before curling in a sumptuous free-kick to put Blackpool in the ascendancy.
However, a low Chris Samba drive shortly after half-time cut the arrears and set up a tense finale and persistent Blackburn pressure told as Hoilett grabbed the all-important late equaliser.
Steve Kean's Blackburn were the first to create a clear-cut chance in the 18th minute with Steven N'Zonzi heading the ball wide after Blackpool had failed to sufficiently deal with a looping Brett Emerton corner.
Just three minutes later, Luke Varney thought that he had put his side ahead after prodding home a beautifully-whipped Adam free-kick. However the Tangerines striker was correctly ruled offside but what angered Ian Holloway's men was the delay in making the decision.
But on 25 minutes, referee Howard Webb adjudged Blackburn defender Ryan Nelsen to have tripped Gary Taylor-Fletcher in the box after he received a smart, reverse pass from team-mate Jason Puncheon. Although, on closer inspection, there appeared to be minimal contact.
Adam sent Robinson the wrong way to side the ball into the bottom right-hand corner of the net to give Blackpool the lead.
If there was controversy in the visitors' opener, then there was no doubting the quality of the second as Adam curled a sublime free-kick into the roof of the net and past a stricken Robinson just four minutes after the Tangerines had put their noses in front.
The two goals sapped the energy out of Blackburn and, apart from a couple of tame efforts from Samba and Hoilett, went into the half-time break with their heads firmly down.
However, Rovers came out for the second-half with all guns blazing and cut their deficit in half through Samba in the 49th minute.
Kingson, who had looked unconvincing when coming for crosses all afternoon, failed to collect a deep, in-swinging delivery and the ball eventually made its way to Samba, who took a touch before rifling home.
Martin Olsson hit the post with a rasping left-footed drive from the edge of the Blackpool box in the 53rd minute and Samba almost grabbed his second in the 78th minute but his goal-bound header was cleared off the line and, just three minutes later, a whipped Jermaine Jones delivery took a slight nick off Hoilett on its way to clipping the outside of Kingson's post.
However, Holloway's men are renowned for their attacking ability and could have restored their two-goal advantage with two stinging drives from Puncheon in the 55th and 66th minutes which Robinson had to be alert to when palming away.
But Blackpool were punished for Kingson's poor command of his area as Hoilett pounced deep into injury-time to ensure honours were to end even.
The result, however, does little to help either team's plight as both Blackburn and Blackpool lie just above the relegation zone with eight games of the season remaining.
