Nivea celebrated their 100th anniversary with a sweepstakes. Special codes printed on-pack gave users a chance to enter the sweepstakes for a trip to see Rihanna perform live in Prague. We built a microsite that allowed users to enter their codes, confirm their sweeps entry and access special content. We also architected a solution to handle bursts of traffic each time Rihanna (who has over 70M followers!) tweeted and posted special codes on Facebook.
