1. Heineken launched an Instagram-based scavenger hunt campaign called "Crack the US Open" to promote its brand and give away tickets to the US Open tennis final.
2. The campaign stitched over 200 photos together to create a mosaic panorama photo that users had to search through to find clues leading to the final photo within three days.
3. If users were the first to find their way to the final photo and comment the correct code word, they would win a pair of tickets to the real US Open final. The campaign engaged 1,500 people and increased Heineken's Instagram followers by 20% during the contest.
