FANS of KSI and Logan Paul queued around the block for the chance to win a solid gold bottle of prime worth £405,000.
The social media stars have opened two separate stores in London and New York to celebrate selling one billion bottles of the energy drink.
Within each store is a 24 karat solid gold bottle of Prime worth £405k.
To win the bottle, entrants have to crack a code on the bulletproof case which contains the Prime.
Fans must crack a six digit code to release the golden bottle from its case.
Each person gets just a single guess which must be made within 20 seconds.

If no-one guesses the correct code within 48 hours, the Golden Prime bottle will be completely destroyed.
Former NASA engineer Mark Rober, who was entrusted with designing the bulletproof case to hold the bottle, has also included one other feature.
Directly beneath the bottle is a vat of molten lava, which is waiting to consume whatever is dropped into it.
In the promo video, he explains that the bath of molten copper is set at 1,093C - a temperature required to melt a 24k solid gold bottle of Prime.

Earlier on Friday, KSI arrived at the central London store in a gold ambulance.
Emerging from the vehicle, he clutched a gold briefcase containing the gold bottle of Prime.
He then entombed the bottle on the glass case, ready for a contestant to try and crack the code.
KSI wore an all-black ensemble, which complimented the gold theme nicely.
The store was decked out with a gold theme full of gold paraphernalia.
The YouTuber and boxer also posed for photos in a gold Prime-themed phonebox.
There was also a pair of gold trainers and a black and gold boxing robe.
Prime is also involved in the world of sports, as the official hydration partner of the UFC, Arsenal, Barcelona and Bayern Munich.
