won a game. how do i get it?

Yea. He will either post it in the key field, send it by mail or add you on Steam. You have sent games yourself. So just wait.

Once the creator sends the key you can find it here
Or if its a gift they will add you on steam.
If after one week you don't hear from them you're allowed to add them on steam to ask about it.
Just be a little patient!

Usually they will either send the key directly through steamgifts or they might add you on steam or send an email. Be sure to check your spam folder if they go the email route!

If it's not there just wait, the GA creator has 7 days to deliver it. Or maybe he/she sends it by email or contacts you on steam.

ah ok. had never won one before so no clue. i have given away alot of games but i always entered a key and then had the option of send key. just making sure there wasnt something i was missing.
