Disclaimer: It really depends on the girl and the dynamic of your encounter. If I #c during night game, I generally text once I get home at the end of the night (unless I have company). That way, you're fresh in her mind, still have some attraction, and may get enough of a convo going to carry you over to day 2. Worst case, you'll figure out she's a lost cause before the morning. While there are no rules, I like to feel out my chances as early as I can. Even in your case, don't wait too long, or you will be forgotten. If you keep fresh in her mind, you can continue where you left off. Here's a somewhat recent example of my text games. Sorry about the length, but it's entertaining.
Wanted to try out a new opener (thanks to whoever thought that one up) and had some fun with it. Waved HB over with one finger, and said "I just made you come with one finger, now imagine what I can do with three." Forget what I did for midgame, but she #c me (also mentioned she was drunk).
After a few more hours at a different bar/club, I got home and sparked the following.
Keks: Haha, you were really drunk tonight

HB: Lol yea I'm sorry about that! I'm really glad to have met you... you seem pretty awesome!
Keks: I am! And you entertained well, though I'll accept a sincere apology for your inebriation in the morning

HB: Haha well since you're so awesome we definitely have to catch up tomorrow... lookin forward to it!
Keks: Hit me up, I'll be stirring trouble somewhere...
HB: Sounds good! Trouble maker huh? Kinda cute!
Keks: I try to be good, but somehow end up causing debauchery... Glad someone's forgiving to a troubled kid

HB: Haha good news... you've met the one person who will set a good example for you! (minus the whole being drunk part). Not gonna lie though, I'm pretty interested in finding out what kind of trouble you get into

Keks: Please, show me the righteous path, and I may confess some of my prior sins...
HB: You MAY confess prior sins? Pretty sure I could make you confess them all love
Keks: Doesn't that sound promising? Reeks of salvation

HB: It does! Looks like you chose the right bar to pick up a drunk girl in tonight!
Next day (Saturday), I continue. Since I wasn't going to FC her, I tried to get her bring her friend out for my wing.
Keks: So how about those confessions... Or should I wail til the Lord's day?
HB: Good things come to those who wait, right?

Keks: You tell me... But I'll get in trouble again tonight, so we'd have to do-over on Sunday anyway. Maybe you can keep an eye on me this evening

HB: Possibly! What are your plans?
Keks: I have the kids this weekend, so I'll be out with the boys. Probably starting at XYZ.
HB: Sweet! How many kids do you have?
Keks: Honestly, I've lost count. I think one of them is having a sleepover, so should be a few. Of course I understand if that's too much parenting for you

HB: Well I have six, so hopefully they'll get along
Keks: Mine are well behaved, they don't follow my example...
HB: Lol mine are wild for sure... but very cute. Two of them kinda have issues with biting
Keks: That's actually kind of hot

HB: Lol I'm totally kidding though. But one day maybe two of my kids will actually have an issue with biting.
HB: So... sad news. My friends and I were gonna go out tonight and were thinking about XYZ area BUT I can't find my ID.

Keks: Party's happening without you, although that's not to say you're fungible
HB: Haha of course I'm not! I'm exhausted from last night though so a night in is sounding pretty good right now.
Keks: Now that sounds like middle aged mom talk...
HB: I know, right! This is rare for me. This is great though, I'm so comfortable and the rommates are out so I'm totally loving it... don't be jealous
Keks declines the invitation and goes out sarging instead.
The following Monday.
HB: Hey you! How’s it goin?
Keks: Vegging, what can Papa do for you?
HB: Haha you’re freaking adorable. I thought about you for a brief minute so just thoughts I would say hello and see how you’re doin this fine Monday...
Keks: A brief minute? You can do so much better than that. I deserve so much better than that!
HB: You gotta sweep me off my feet or something... silly boy!
Keks: Demanding extraordinary deeds already? You need to stop watching those movies all day...
HB: Lol so you’re saying you can’t sweep me off my feet then?
Keks: Wouldn’t you like to find out

Admiteedly, I’m no Hugh Grant, I am way taller!
HB: I’m starting to doubt you Mr. Keks ☺ I’m kind of ok with you not being Hugh Grant... I’m pretty tall myself. Plus, anyone can fake a British accent.
Keks: That’s why I fake a German one

HB: Hahaha very nice... so who are you REALLY?
Keks: I told you, I’m Papa Bear. The one with the honey

HB: Oh I see... duh! So when do I get to see you again papa bear?
Keks: Papa’s leaving for [other city] Wed morning. Should he bring you back some [other city’s food specialty]?
HB: How thoughtful of you! That would be lovely! When do you get back?
Keks: Sunday, try not to miss me too much

HB: I’ll try... although it could never compare to how much you already miss me after just that one drunken conversation. I’m quite the charmer ya know

Keks: Good think I have a support system up there... coping any which was I can!
HB: They have support groups and stuff too. If you need the contact info I’ll be glad to give you that. What are you going to [other city] for?
Keks: For pleasure!
HB: Just a random visit?
Keks: Because I can! Only live once

HB: Nothing wrong with that! Do you have Facebook or anything?
Keks: I have a messenger pigeon and a statute of myself in my hometown. Does that count?
HB: Yes! That’s WAY better than Facebook... you definitely get points for originality!
Keks: Maybe I’ll send you my pigeon while I’m gone. He’s quite friendly actually.
HB: I hope you do! Does he have a name?
Keks: His name is spot, because he barks sometimes
HB: Lol Hmmmm a barking owl? Explain please...
HB: And by owl I totally meant pigeon
Keks: He had a troubled childhood. I try not to ask questions...
HB: Poor thing. He must be so confused! Probably didn’t help that you names him spot seeing as how that’s more along the lines of being a dogs name...
Keks: Don’t you guilt me about my parenting... I’m a loving, caring owner!
HB: That confuses his pets about their true identity... you have to tell him the truth someday. He deserves to know
Keks: You do it while I’m gone. I don’t do trauma talk

HB: So you leave all the hard work up to the ladies? Is this how you win them all over? lol
Keks: Now you know how Papa works!
HB: Well dear, I’m different from most ladies so you might actually have to do some hard work to keep me around.

Keks: Bye bye HB
Yes, clearly blew her off. But since she didn't bring her girls out for my friends, my interest was gone. But I enjoyed the game in the meantime, perfect prep for sarging....
