They beat the other acts in the public's top three, young ballet dancers Tayluer and Elliott and theatrical outfit Fear Of The Unknown, after a shock result that saw all the street-specific groups eliminated, alongside Sweet Surprise.
The judges were wowed by Prodijig's final routine, with Adam Garcia commenting: "You actually have surpassed yourself again. The level of excitement that you induce in me just watching it is so thrilling."
Kimberly Wyatt said they were 'professionalism at its best', while Ashley Banjo summed up: "If I shut my eyes, and try and picture a quarter of a million pounds in dance form, that's what it looks like."
Fear Of The Unknown and Tayluer and Elliott also impressed, but particular praise was given to the classical duo, aged eleven and eight, who pulled off some jaw-dropping lifts and twists.
Ashley said it was 'arguably the best performance we've ever had', while Adam stated: "The technical difficulty is of some of the hardest lifts I've seen anywhere in any performance. Not only that, you dance with such beauty. Every box has been ticked. If you're not in the final three it will be criminal."
Elsewhere, Boadicea, Methods of Movement and Unity UK got top marks from the panel, but Kazzum and A-Team's performances fell flat, recieving three red stars each. Antics and Sweet Surprise had mixed reviews, with two golds each.
After the ten finalists danced - in front of an audience of 6,000 at London's Olympia - the public chose their top three, who performed their routines from the semi-finals again before the winner was revealed. Sky said that the amount of votes cast during the final was up 20% on last year.
Once host Davina McCall announced the result, the stage was swarmed by all the acts and Prodijig's friends and family, while last year's winners Chris and Wes appeared to present them with a trophy.
The show is set to return for a fourth series in 2013.
