For "Henkel Bulgaria" Mag Studio created a special online game - "Persil Cold Active". Both the concept behind the game and the design and development are by Mag Studio.

The aim of the game is to clean with the help of Persil Cold Active certain clothes as fast as possible. The players must tackle four types of stains - motor oil, lipstick, tomatoe sauce and make-up. Every week "Henkel Bulgaria" gives away prizes in the form of 16 kg washing powder - the amount needed for one household for one year as well as a Bosch washing machine.

The online game markets the new detergent Persil Cold Active, which cleans the above stains at low temperature of 30 degrees. According to data from Google Analytics, the game is being played not only in Bulgaria but in 40 other countries around the world.
