You can’t cheat in Evony.  There are however a few ways to enhance your prestige.

One way is to build 1 warrior. 1 warrior will get you 1 prestige.  You can do this multiple times and keep getting 1 prestige.  This is increadibly time wasting and close to useless as it only gets you 1 prestige.

Another way is by spending real money.  Real money can be spent through paypal or by Credit Card.  What you can buy are “speed ups” to build buildings faster, or research quicker.  Or you can buy spins on the lucky wheel.
