Out of interest what is the best way to game a flake, has anyone had any experience of this ? or should you just leave them ?

First flake:

Her: Hey sorry, <insert bullshit/possibly true reason here>
You: Oh hey, its cool. I've sorted something else. <even if you haven't, pretend you have.

second flake do the same thing.

third flake. drop the girl, go game others. She ain't worth the time.

^Good advice.
Just be nonchalant about it.
It's more of what you shouldn't do.
Don't try to make her feel guilty.
Don't start asking for another time to see her.
There should be an image that you can easily fill that time with something/someone else.

Imagine if you flaked out on a chick.
The only good response for her to keep her face would be to say something like "it's chill."
With anything else, you'd be gaining clear leverage.

18 Body Language Mistakes I Bet You're Making

Ah thats cool, what about this, a girl who set up the date, flaked on me last week. Ignored it but recently sent her a jokey opening text completely random, she responded well and has shown iois.
Should i forget her because she flaked on me, or if i was to game her, how is the best way to approach it, negs ?

Post the convo log, be more descriptive. Its hard to help when you don't help us.

Well when she stood me up on the coffee date she organised, after calling her a couple times, she texted me saying she was moving house today and said she would call me. I didn't text back from that and she didn't call.

About a month later i was bored so i was sending bitches random texts, for experimental purposes
So i sent her a blank text, she responded with a smiley face
And then i started asking her for help, saying meet me at this location in 45 minutes to help me steal a christmas tree.
She played along with it and i nagged her a bit saying she was lame.
Anyway i left it as that and she recently liked a couple of pictures of me on Facebook.

I got intimate with her in a club so she is defiantly attracted to me, i think i just presented too much interest when i responded to her asking me on a date.
