Dont you think that some girls dislike that you dont talk to them for a day or so especially if they really like you even though thats the rule that once you get a number you wait atleast a day or two to call or text them or do they like it because it shows that your not needy?

Who cares what she likes? You should not be concerned what she is thinking or what she wants unless you're already in a long term relationship. The only thing you need to think about is "Should I like her yet?" not, "Will she not like me if I don't text her?" In fact, trying to please her conveys neediness which is a huge turn off.

As for a non inner game answer, it really doesn't matter when you call her - you just have to make sure you remain a challenge no matter what you choose to do. If you wait a few days, yes that shows you're not needy, but if she likes you then why wait? You can remain a challenge even if you call her the very next day, just keep it cocky/funny. Start a text convo and make it seem like she is trying to seduce you or hit on you. Make fun of her and bust her balls. Those are just some examples, but my main point is just keep the attraction going by maintaining some tension and remaining a challenge so that she will chase you.
