If you ever see people on your server that are selling 100 gold for 1 Red Wrapped Gift or anything along those lines and they claim there are Mounts and Pets in it.
Don't fall for it, I see people do it everyday on Illidan Horde and for those who fall for it and open a gift of nothing you have lost your mind.
They will say, in every 160 gifts there is 1 Mechanohog Chopper so that would be 16k gold so that makes since, but honestly who wants to put there valuable Chopper that is liquid and will sell quick without having to go through the trouble of wrapping 160 items and finding people dumb enough to buy them just waiting to be scammed. People that are addicted to gambling and that like to play the "Roll" games partake in this. I have done the "Roll" games and won a lot of gold off it but it was because I was doing it myself and my own rules. Although, you cannot get banned for Red Wrapped Gifts, but you can get banned doing roll games I have gotten banned many times for temporary times.
As of when it comes to Roll Games, never play them unless it's something like Blackjack.
The player will roll 1-11 and the goal is to get as close to if not hit 21 exact.
If the player busts the dealer wins, if the player stops at let's say 20 and the dealer can't beat it player wins.
The winnings for the player is x2 gold that they gave to you, but the dealer will always have a edge because the player will play first and have a chance to bust out of the game.
When it comes to those games were you roll 70-95 and you get x2 and 96-100 x3 and those are your only chances of winning, save your money and host your own Blackjack game or if your looking to gamble only play Blackjack it's a lot of fun with fair probability.
