There are places in Paris where you can’t get any Internet connection. So Ogilvy Paris setup free Wifi hotspots in these areas and incentivised people to make use of the wifi by first playing a short game of ‘Scrabble WiFi’.
Once the user proved his spelling skills, the score from the word was converted into free wifi minutes. The higher you scored, the longer the connection. Sharing the score on Facebook also doubled the connection time.
