how do you higher your chances to win?

Being here for more than a day helps a lot. Grammar will make people not hate you. Using the forum search function is nice too.

Ok, ok, serious answer- You don't. It's 100% random. Try searching for giveaways with less entries. And unless you think you're very lucky don't expect to win any time soon. :P

Buy 10 copies of skyrim/sleeping dogs and give them away.

You could try entering more than 28 giveaways? How many did you expect to win by now?

Magnets.

weren't you the kid that wanted us to give you games.
Sorry but if such a thing exist, everyone will be doing it.
The only way to heighten it is to go into on with lower entries and you do that by contributing, being part of groups, and knowing people

Less entries = Higher chances

Figure it out.
