nVidia Drop Event in Aika (USA and Canada)
You just have to fight MOBs in the world of Lakia. If they are within your level range, they will drop an nVidia token. When activated, this token will either give you a Lottery Ticket or an nVidia Box, an item that will give you a random in-game reward.
At the end of the event, 3 lottery tickets will win a Grand Prize of nVidia Graphics Cards, and 40 more winners will receive Limited Edition Aika Snuggies.
