well if she isn't being receptive to the techniques it might just mean that she is just not even into you. Remember not every PUA gets EVERY girl he wants/desires, he will fail more often than not, but what i would do if a girl isn't being receptive to me, and almost ignoring me, i would probably have a lot of fun with it at that point, because here is where you can experiment with new ideas and what not. First i put a time restraint on if you haven't already, so then maybe she will ease up and just go with it until you leave. Second i would ask her something to get her interested and that requires her to give me her full attention, for example "hey i have a couple minutes left to spare before i have to go back to my friends (or whatever) and while i have you here i was wondering if i could try something on you?" or "really quick and then i have to go i was wondering if i can try a little experiment with you?" then at this point she will probably be receptive, BUT if she is still non receptive, start to build a yes ladder say "okay but before we can start i need to ask you some questions. Are you interesting? Are you creative? Are you exciting and adventurous?" obviously she will say yes to all of them and if not then neg cause she will probably be a bitch and you need to level the playing field, so be a little bit of an asshole, but not in an offensive way. after she creates the yes ladder than you can say "okay good, so lets proceed" then you can go into the "cube" routine, if you know how to do that, which works well because you can then Isolate her (if she is not isolated) you can say you need to sit down, and it also involves touching, and you can be like okay give me your hands and hold them while she thinks. At this point if she still seems unreceptive you can either just go along with it until your done or you could pull out your cell phone and be like "oh sh1t im actually late for something now, i got to run, but it was good meeting you" or whatever you want to say. If she starts to get interested, and you get almost everything on the dot, then you say that you have to go and you would like to do it again sometime. I dont think that i would ask for her number, just because at this point she may feel obligated to and thats just awkward when someone gives you her number, but just say you enjoyed talking with her and you will see her around, and leave it at that.
Thats what i would probably do. i would actually when playing a game with her i would go into the 5 question game, but before you do you make a bet, over a cup of coffee or whatever, so then if you win (which you will) than you can say your going to take her up on her bet and TELL her to give you her number say "alright i got to run, but give me your number and i will take you up on that bet sometime" or whatever.
I hope i could help =] let me know if you have any other questions
