This game was on some other forum I went to Basicly, it work's kind of like "The Last Poster Wins!", cept you have to 'steal' a 'hill' from the poster above you, using clever tactics to get him or her off the hill. Then you claim the hill until the next poster takes it from you using clever tactics. Sound easy enouth?
If you got any questions on how to play, i'll gladly post an example. However, I hope the following text is a good enouth hint;
"I use all my pokemon to atack non-exsistent poster above and run up with them to claim my hill. QUEEN!"
