You can have the whole group attracted to you. While there's possible to game all of them, it's easier to game only one using only MM. If you're after all of them, you need to blend stuff. Be the leader of the group and interaction. Neg them as a group. Be genuinly interesting. Build social proof by using the proof you get from them. If the girls see that the other are attracted to you, pre-selection has been established for all of them.
The problem comes when building comfort. This is the easiest with either one or two, not five or six
If you want to close more of them, number closes is what you should rely on. Get day 2s with a couple of them, because if you start kiss closing on the party and the others girls know, you can't go back and close the others.If you want to do it safe, settle down with one target or schedule day 2s.
