Contest in 'instant win' mode on single channel.
Jackpot: 15 vouchers for 2 people.
We designed a Facebook app with automatic login.
Users can choose the country where they would like to go in case they win one of the vouchers.
After choosing the location, the system determines the result of the game. Winners can then confirm personal details populated from their Facebook profile. Whether winning or losing, the users' timeline will show their participation into the game.
