dm Bulgaria turned 8. We have celebrated the birthday with an online game that is both entertaining and informative. We created a virtual replica of a dm store, hiding 8 cakes among the products. Consumers had to look closely to the shelves to find them. At each game loading the cakes turned up on different places. Thousands of users tested their observation skills and got to know closer the wide range of products in dm, 100 of them won coupons for a 15% discount in the physical stores.
