Coca-Cola has unveiled its Super Bowl strategy; a social game that relies on fans to pick the ad’s ending. ‘Coke Chase‘ follows three different groups (Cowboys, Badlanders, and Showgirls) in a desert all trying to get to a Coke first. Fans will be able to vote for the group they want to see win and ‘sabotage’ the other groups, which will determine the spot that is unveiled at the end of the big game.

A 30-second teaser drives fans to CokeChase.com, where they can get a first look at the 60-second ‘Mirage’ ad that will air during the Super Bowl and begin voting for their favorite group. Once they’ve cast a vote, visitors can commit an act of ‘sabotage’ against an opposing group to delay the rival teams. Fifteen different sabotages depicting a lighthearted scenario, event or detour have been filmed.

As the final whistle blows and the winner of the big game is celebrated, Coca-Cola will reveal the winner of the Coke Chase based on fan participation throughout the game via a 30-second commercial that completes the journey.

The experience builds on last year’s social experiment, where the Coca-Cola polar bears reacted in real-time to the game. Relying on fans to determine the outcome plays to a larger crowdsourcing trend that several advertisers are utilizing this year.

Doritos asks fans to create the spot with ‘Crash the Superbowl’, Pepsi is asking fans to submit photos of themselves for a half-time spot, Pizza Hut will feature fans in their ad, and Lincoln turned to Twitter stories about crazy road trips to guide the creative for their spot.
