Four games where you are able to convert virtual money into real currency. All these games are completely free. There are functions to invest money if you want to, but it's not necessary. And I'm not saying that you're gonna earn thousands of thousands or something like that. In the beginning you will get small amounts, but in time your earnings will increase. Everything is up to you, your decisions and strategies can make you real money.
To find information about the games:
For MarketGlory it is called Documentation and you can find it on the top of the page in the black background.
For GoldenBattles you also need to register, then log in and then go to Help it's written in white letters and is above everything on the top of the page.
For GoldenTowns also need to register first, then log in and there will be 7 sections, you can click on any of them, it doesn't matter, but don't click on home, because you already will be in this section when you log in. So when you click on one of the sections except home on the left you should see some grey icons, one of those icons is the book with a cross on it, when you take your mouse on this icon there should pop out the words Help, faq & customer support, just click on this icon and there will be information you need to know.
