In saying that, I have to agree with Patatas. Just be aware that this isn't a "double your BTC in 24hrs" type investment... and it isn't a 10%/day type HYIP either... nor are earnings guaranteed, I spent the first 5 days in negative profit... bad timing on my part
In their favour, Crypto-Games seems to have a loyal group of players and they have some nice features that attract people like supporting multiple crypto currencies, easy faucets, a rainbot in the chat, MODs and Admins who are relatively active on the site so getting help/advice is usually relatively quick. Deposits only need 1 confirmation and free withdrawls if you're happy with possibly "low priority" transaction fees being used.
They take investments in several currencies, and all currency investments are treated separately, so you can spread your risk that way... Your investment profits are not paid out automatically on a daily/weekly schedule as such, You have to manually cashout your investment... but profits do compound, so you earn profit on your profit until you cashout
But, I'm a happy investor and will continue to stick with it for the time being and hopefully watch my BTC investment grow
