Since you have only won 3 games in the past, I think you should join the following giveaway group to increase your chances at winning.

And always remember only to enter games you like to play (e.g., wishlisted games) so you can always be happy about the games you won.
For those who play their won games, there is another two groups you can join.

Good Luck! 👍
