Ülker organized a big sweepstakes campaign to support chocolate sales, utilizing codes in the product packages. Consumers who sent the code via SMS, website, mobile site or Ülker Çikolata mobile app participated in the sweepstakes to win 1 Mercedes automobile or 100 Arçelik televisions. We took part in all stages of the campaign, from code production to the General Directorate of the National Lottery permissions, from the site and application software to the development of the participation infrastructure.
