The Sound of Green

The Swedish Post has a collection of pre-stamped parcels that makes it easy to send things. The task for ad agency Akestam Holst was to tell people that it was possible to send almost anything over night with these pre-stamped parcels.

So they packed 80 parcels with all sorts of stuff and then recorded 80 specific sounds. These sounds were then used to launch what they called ‘The Sound of Green’ competition. Here the users had to pick a parcel and pay close attention. If they could figure out what was inside, the Swedish Post would send the same parcel to the winner the very same day.

After 140 240 guesses the competition finally came to an end.

Jeep Puzzle for Twitter

Leo Burnett Iberia is running “Jeep Puzzle”, a first of it’s kind online action that turns the microblogging platform Twitter into a real playground.

The competition invites users to complete puzzles using several different images from Twitter profiles. Each puzzle represents landscapes which only Jeep can access. Users who complete any of the puzzles can win prizes including T-shirts with the exclusive Jeep Icon design.

Leo Burnett Iberia created more than 371 Twitter profiles in order to include all the puzzles and their pieces. Ten main Twitter profiles each follow 36 profiles!

Why this worked on Twitter

The clever part is that the “platform limitation” became the mechanic. Instead of treating Twitter profiles as static identity pages, the campaign used profile images as modular puzzle tiles. Following connections became navigation. And discovery became play.

It also kept the brand role tight. Jeep did not need to explain features. The landscapes did that. Each completed scene stood for the places “only Jeep can access”, and the reward system (exclusive Jeep Icon T-shirts) made participation feel earned.

What to borrow for social mechanics

  • Build the experience out of native objects. Here it is profiles and following.
  • Make progress visible. Every solved piece changes what the user can see next.
  • Let the content carry the brand promise. The landscapes are the message.
