can i make private giveaway for only one person?

He want to cheat and increase his gift value/total points on site.

Shame on you for trying to boost your giveaway value. Just give him the game and be done with it.

yes, you can do that; yes, he certainly wins; no, you don't get gaveaway value..

there is not restriction i think, but it's sounds to me like cheating :D

giveaways require more than a few entries to go through otherwise it won't count at all.
