Whait is the difference between FXGame and demo account?

Whait is the difference between FXGame and demo account? Is it different with regular demo accounts from most borkers? Can I make backtesting, to test strategy or something else? Does it functioning like forex simulator like stock pc games? I wonder if I can make backtesting with it, becouse its name is different, not demo account.
