Once you get into the correct mindset, it won't be a game. It will just come naturally. Let me explain.
First of all, once you have set up the date, it is best to not initiate any texts with her, but if she initiates you may respond but keep it light and brief. The more you text her between the date, the more chance she will flake. Don't ever text her ''making sure you're still on for our date'' or anything like that. Assume she will show up.
With your question about not responding, it would be rude to ignore her, but you have to know when to stop the conversation. You don't want to turn into her texting buddy. I just go with my gut and always try to leave her wanting more. She may send something that doesn't need a reply, that's a great time to end the conversation and it also shows you aren't needy. If she keeps shooting questions at you just say you're heading off somewhere and you look forward to finishing the conversation on your date. Just remember that women don't know what they want. They will try to have day long texting marathons with you but ultimately this will likely kill her attraction and lead to flaking especially if you haven't banged her.
I even go by these principles with girlfriends. If I am not setting up a date/logistics, flirting or making her gina tingle then I generally do not text her. She can text her girlfriends about her day, you are a man of action.
