refresh that page

1 contest already done
the other started just a few mins ago, i think

go go go

and refresh that page for more contests i guess during the day

note: seems its 50 keys per contest so its a "hurry hurry hurry" thing hehe
note2: "3. Winners will be picked daily!" it says.. hmm so 50 keys a day? maybe....

edit 5th february:
turns out only ******* and myth-games gave out their keys right away
the other 2-3 sites went stupid and only give out 5 keys a day/not until after sunday
