Tallink Shuttle is the fastest way to get from Tallinn to Helsinki. Only 2 two hours and 6 times a day. Just as easy as looking at a banner for only 15 minutes.
We created a banner ad that went live 15 minutes before the start a Tallink Shuttle ferry from Tallinn and every user on that banner was urged to keep their cursor on the banner for a chance to win a free ticket to Helsinki. Every day, 6 times a day, one lucky (and very patient) user won a free ticket. Just for staying on the banner.
Surprisingly, a lot of people were very patient.
