Giveaway Websites

FREESTEAMKEYS.ME ~ You get steam notifications by subscribing to a thread which mods post on when there's a new giveaway. Giveaways are very frequent, can get annoying if you're not interested anymore. Most of the giveaways use Gleam. Usually, there will be a couple giveaways for the same game which gives you a chance to get the game again if you missed the other one(s).

MMOBOMB.COM ~ Giveways are better quality and less effort. Some giveaways aren't for Steam. There are some expensive dlc packs that aren't instant and you have to compete to get.

GOOGLEING FOR FREE STEAM KEYS ~ You might find some random sites offering free beta keys, if you"re lucky.

INDIEGALA.COM ~ You need a indiegala account linked with steam and you need to be in the indiegala steam group.
