Hmm ok...
As with any form of game text game is about picking a specific goal and heading off in that direction along the
most suitable path. Whilst it should be viewed as just a game i.e., you can hit restart every time you crash and burn and you shouldn't feel a lot of emotional pressure to get any outcome (this mentality is the most effective cure for AA by the by

) you need to play with strategy.
My credential? Three months back consistently flaked upon by no more than 6.5s, Now? Bar the occasional missed beat consistently get flirty and when I feel like it dirty by 5th text or so (often haven't even met the girl).
My advice:
1. GOAL. You need to decide what your aim is so you have a direction to head in whether your set on a day 2 or day 1 if you haven't met. To maintain interest you should always try to lead up to a meet.
2. Select PATH. So say I'm gaming a HB8, I've met her once casually through a mutual friend I want to get a day 2. To make my life easier I would always have initiated with a flirty C&F vibe when we met as I find this is the best way to be in text game initially. Ok, I'm gonna try to build attraction/interest here working on what we had before culminating in a semi-casual meet up, I'm going in cocky funny, I'm going to pull a few tricks to get comfort and familiarity but flirty so things don't go all AFC on my ass

.
3.GO! I start with something a bit cheeky like a tease (very obviously light hearted and funny) usually a joke which we had at the first meet, if you can't tease try something appropriate from the cornucopia of openers available on the net .Consider: Any HB8+ and many social HB7.5s normally have a plethora of text flirts under their belt. About 75% of those will begin thus "~How are you/hows your day been/wat u up2?" By all means go for the standard lines but jeeze don't expect good game

. The name of this game is to entertain, you need to maintain interest and wheel it in the flirty direction to give her something outside of the norm. This is similar to Adam Lyons "Breaking Rapport" concept, look it up its good stuff. Finally: NEver give more than you get, if she doesn't respond wait 24hrs at least before sending a second text (always short and teasing). Very your response times, you are a busy social guy and she should be waiting for your response not vise versa. Be indifferent, i.e., don't emotionally attach to the idea of dating this girl just... play the game

.
4.FRaME conTrOL. This is the biggy and really its not a specific move to pull more a style in which to play which straddle 3, 5 and 6. You need to be the one setting the presidents here. She asks you whether you work out for example (haven't had this myself but it does happen) you spin it into role reversal (5, below) with a "I hope you're not only interested in me for my pretty face and manly physique".
5. ROLE REVERSAL. You know how the pros always go on about getting girls to chase you? Well this is simply that. With the C&F vibe going its easy at points to introduce the idea that she is chasing you. If you've got her laughing along well enough then throw in a "I hope your not chatting me up

". N.B. It needs to be at a point where she's comfortable and humored enough to play along. If she doesn't give a neg then carry on with C&F for a bit then try again. I've had this one supply me with absolute gold. I've actually had a girl start pushing for my no. and put a sexual spin on the whole convo just by running with the her chatting me up thing. N.B. You still need to maintain ALPHAness as it were, so don't play the weak maiden play the funny sexy guy who gets numbers all the time...Remember to control the frame also.
6. ESCALATE. Now you should turn on the flirt i.e., get a bit suggestive, throw in a few minor ISIs and build it all up till you feel your a little way from hitting peek interest THEN get her NO if you're fbing. . I've now got to a point where I can get quite a few girls to ask for my number/contact details from the internet (not that thats and achievement or anything

). If you've gone text from internet run the role reversal stuff a little longer and maintain escalation gradient. Once you're almost peeking go silent for at least an hour or more, depending on flirt intensity, via not answering her texts. This gets them waiting on you which is KEY!
7.MEET. Day 2s shouldn't be explicit DATES per se, rather a casual meet. I find the best day 2s are where you invite the girl along to accompany you round town on a few errands. This is very mystery method esque in that you're going in a little under the radar. You should indicate that you are going to do what ever it is anyway making it clear she is joining YOU on your grounds doing your thing (Alpha stuff blabla). Any how this is not a guide to day 2s and I don't yet feel qualified enough to give day 2 guides but...meh. If she says no, don't sweat just carry on flirting and try again in the same way later. Rejection can often be dealt with by inviting her to a group thing, much more safe etc... I'm doing it again!
I know this doesn't explicitly answer your question but the materiel the other guys have given you combined with this guide should see you through now and forever more. Text game like any game is one that requires skills attainable via practice, but because you've got time on your hands to think up a response you can apply a lot of game rules much more smoothly than say during a cold approach. Feel free to critique everybody
EDIT:
Regarding frame control flipping roles etc, when asking her to give you some interesting detail about herself always spice it up a bit so it doesn't seem to judging.
