Wow, I must say that's a pretty unique idea for a giveaway. Every casino runs its giveaways and promotions, but we usually see most of them using the same type of giveaways and basically the same games or whatever methods they use for their giveaways, but I see that BetHog is putting extra efforts in this area as well.

That being said, I wonder how they will choose the winner, but what I'm thinking is that they will probably do it using a random number picker, by inserting all the numbers available in the giveaway, and letting the tool pick one number, and that number becomes the winning number, hiding the Ace, and the user who has selected that number, or have selected it first if they allow multiple users to choose the same number, that user becomes the winner.

This way, other users won't complain that they've been cheated or anything like that.
