I have bought the 20k gem pack since it came out. They don't work. Gems are a hoax and waste of money. Don't end up like me wasting money in a game you will not see any achievements. People who got up to mega billions cheated and I know this cuz I was one of them. In a place that always takes you use an advantage when you see one. There is nothing fun about this site. The games are average. I will say 4 years ago it was a great online casino giving fair prices. You knew if you lost you could buy some extra gems for a pick me up but now it is worthless. Trust when I say I have 98k in gems and 38k in party passes. I WILL NEVER USE THEM. It is crooked game and it will not give you anything if you use. Don't waste your time here this is possibly the worst online gaming site ran by the greediest of all people. They started giving away 100k lottery in gems, if they were really worth something they wouldn't be given away. It's all a scam don't let them take your money or time. I'm not a bitter player I have over 200 bill but it is useless waste. If it want for my glitch I wouldn't have any money cuz the 20k per week in gems had me lose money not gain. I could talk until I'm blue in the face but mark my words 3 months in playing the game you will be singing the same tune.
