I woke up this morning thinking about kiss closes and how most of them (that i've seen) are kind of sporadic. I decided to think of one myself but idk if it would work. I am planning on trying it in the next month or so since im soo busy with lacrosse and school and stuff like that. I would appreciate your opinions on this.

Here it is:
The "would you still be my friend if....." kiss close

After building a bunch of rapport, getting IOIs and number closing, you could go into a little game with her.

PUA: Hey have you ever played the 'would you still be my friend if' game?
HB: No/Yes/What is that?
PUA: you've never played? Here I'll show you/I used to play it all the time when I was a little kid. Wanna play(option:say it in a little kid's voice)?/It's a game where you ask 'would you still be my friend if blah blah blah' Here let me show you
PUA: Would you still be my friend if I was handicapped?
HB: yes/no (her turn to ask)
PUA: (answers vary depending on if you want to neg or do other things to get more IOIs)

This will go on for a bit until it's your turn for the third time or so.

PUA: Would you still be my friend if I did this? (go and kiss close)

Well let me know if this is good or not. Thanks for any feedback.

It's a little too gimmicky. Like you said - kisses just happen, they're not planned. At least, not like this. If I was a girl I'd be thinking, "he just wanted to play this game so he could kiss me..." and it'd put me off. It just doesn't seem like a very confident way of going about it.

Instead of figuring out elaborate ways to set up a way to kiss a girl, I urge you to focus more on having fun with her and use kino escalation to allow it to just happen naturally. In the case of being with a group, you can isolate when the time is right. If it's just you and her, you can either do it when it feels right or wait until you're parting. If you hug her with your arms around her waist, squeeze for a few seconds then loosen your hold and she continues to hug you... just go for it. Give her a kiss on the cheek, tease her about expecting a proper one, then depending on her reaction you can go for it. To be honest, there have been quite a few times where I've just said "gimme a kiss". It works. If she says nothing and just looks at you, happy days. If she asks why, tell her cos you want one. Why over complicate things?
