The online game consisted of an advent calendar with a prize giveaway for every day in December.
Participants had to choose the current date and open the calendar box to discover the prize of the day and play the game. They had to collect 15 icons with N9 features within a minute. Icons fell from the top of the page, like snowflakes in a snowfall.
At the end of the game, players could register for the contest and earn extra points for sharing with friends via social media and inviting referrals. The player with the most points won that day’s prize.
