game not appear on list

Drop the key in a thread if you are just looking to be generous. Trade it for profitz.

if you mean newest IndieGala bundle there's not just 2 but like 6 or 7 games you cannot give away ;)

Indiegala bundles are often filled with previously free games. If you check out our Deals forum before making your bundle purchases in the future, our users typically go out of their way to dig up that information for everyone when reporting on active bundles.

If you want to check on your own, you can always simply see if the game is in the giveaway creation list or not- unless the game is still not officially released, it's unlikely to have been removed for any reason other than having been free.

Your options with free keys are:
1, Trade them (I recommend Barter.vg for trading), though free games trade.. well, for basically nothing. They're mostly for sweetening a deal, than making one. They can, however, be traded for other previously free games, which can be to your benefit if you're new to trading.
2, Drop the keys outright (ie, through the Orphan Keys thread), nearly always ensuring that bots or ungrateful ninja users get them.
3, Give the keys away through a forum thread dedicated to giving away the keys, and directly give the keys to a user [you can use random.org to make a custom lottery, and give the key to a random user in the thread, or you can set your own expectations for what user should get the key]. A couple of threads already exist for this purpose, as well, so you can utilize them to your benefit.
4, Activate the keys on an alt account, for card farming (Note, you'll need to add $5 on the account to fully activate it, so this approach requires some investment- though you should be able to then spend that $5 on gifts for your main account, so there's that.)

no, i dont buy the games to give away, its just as i said, i buy the bundle for me, but there are a couple of games that i dont want.
