Well that's not so good event it would be better if this says:
Login and play 12 hours to receive Prize pack 1
Login and play 48 hours to receive Prize pack 2
Login and play 96 hours to receive Prize pack 3
It's really hard to login when in one day you have no network access and you can't login & play. And when you play everyday 5 hours and you miss one day because of an issue of your computer / network it's just waste and you will not win the prize. That's just suggestion...
