Now every game developers are choosing the greedy line to suck gamers $$$. This is really horrible. But there are some geek people also to mess around their income.
Here is a cheat/hack for Rule the Kingdom, but not sure, as I've not used this. You needs to install gamecih software in your LG Optimus One.
Open gamecih, go to input name, type gold. You should get 3 results look for staring gold and change value to whatever you want.
Same with crystals... go to input name and type crystals.
This cheat code is collected from net.
So, do you have any cheat code to get lots of golds and crystals for this game?
BTW, I'm playing this on LG Optimus One.
