I know how to easily win the Royal Rumble on WWF Smackdown 3: JBI. This may sound stupid but my dad has won at least 6 times with this strategy and he isn't even that good. All you have to do is stand in a corner. The lower Left one works the best because the wrestlers rarely end up there. If you should just happen to walk your way just punch or kick him away and the wrestler should stay way from you unless you and the wrestler are the only two left and your waiting for another wrestler to some down the ramp or you are the last two left. If more than one wrestler come your way than just move to a different corner, going counter clockwise works well. When you are the last one left just sneak up behind the wrestler and knock him or her over. They should hopefully be doing their taunt which will give you enough time to knock him or her over the top rope.
