LVL UP

The only way to level up is to gift games to the community ;)

You are asking wrong question. You need to ask yourself, why you want to lvl up. And if answer is "to get more games" - then you should not level up at all, because it does not work like this.

Welcome to Steamgifts.
If you have not already done so, may I suggest you read the FAQ & guidelines. It is also a good idea to keep track of the announcements done by Steamgifts' admin.

In case you are unsure about the rules stated in the FAQ & guidelines, use the search function of the discussion board, as most questions have been asked plenty of times.

Enjoy your stay at Steamgifts & good luck!

Create GAs. If you want lvl up real quick: create GAs of unbundled games.
