You can lose points with RPS and from my experience, you can never win. Supposedly it's fair. Here's an article on it. Other articles can be found under Help & Info.
The winner wins :P
But, anyway, you get more RPS choices with the more experience points you have.
The winner is almost always Cysid. :P
But... But... I've beaten Cysid once! >.> Playing toggle...
I have beaten him in RPS, Toggle, and RPS(Original)
lol this happened to me during my first duel too, If i were you I would either -avoid RPS and play toggle or RPS(normal)- continue to play RPS since you have little to no points becauseyou are new. Either of these choices will allow you to get new signs for RPS.
I do agree that they should make the diffrence between RPS(story) and RPS(normal) more visble.
