Win?

It's been scientifically proven that good things come to good people :D

These are some great tips, I always follow them myself. The only problem here is that the OP has no contributor value yet.

You don't need to be online right when it ends. If you win a giveaway it will say so in a green message on steamgifts. After that, you might have to add the giveaway creator on steam, depending if it's a giftable copy or a key.
