The World Party Weekenders text and win competition will appear on 70cl bottles
until the end of November.
A Red Square Reloaded website - worldpartyweekenders.com - has been created to appeal to clubbers aged
18-24 and features information on the best nightspots around the world as well as UK clubs.
Hamish Thomson, senior brand manager said: "Reloaded is the only caffeine based vodka drink that can truly deliver upon the functional needs of 18 to 24-year-old "weekenders".
"This activity demonstrates Red Square's ability to drive continued consumer interest in RTDs."
He added: "This latest campaign will reinvigorate the category this summer."
