To drive visibility and build sales, WKD Blue multipacks will feature the football-related on-pack offer.
The interactive promotion has the strapline Armchair Army and will give fans the chance to win a share of a cash prize fund of £500,000.
Every pack will include a money-off voucher to encourage repeat purchase and drive footfall for retailers.
Each 10 and 12-pack of WKD Blue will contain a game card with the chance to win up to £2,000, a humorous Armchair Army Guide to the World Cup and a voucher for up to £2 off a subsequent purchase.
Promotional stock will be supplied to trade customers from the end of April.
