Ok buddy, college party house here to help... we regularly have between 60 and 90 folks... heres the recipe.
Alcohol
Make jungle juice.
Buy a five gallon cooler, put in 1.5 or 2 full handles of vodka (as cheap as you can find, you won't be able to taste it), an entire package of crystal light mixers (fruit punch is good) or a bomb of koolaid (entire tub of the powder), fill the rest with water, then add ice.
Tastes great, pretty strong, everyone loves it.
Also, for vodka shots (if you are so inclined), TITOS. It has won all sorts of international contests, is made in Texas, and you can use this pitch to get them started.
"Ever had this? It's titos and it's great, rated higher than grey goose and made in texas, so this is a shot for 'Merica!"
Also, its hella cheap ($15ish a fifth) and crazy smooth, goes down like water.
Music
Not sure on your budget, get a nice set of speakers that you will be able to hear over everyone, if your current setup works? Tight. If not, buy or start asking your friends, one is bound to have at least some kick ass computer speakers that will work.
(we have a DJ bro bring his setup, but just decently loud speakers is all you need, a group of 20 won't require anything too heavy)
Pandora is your friend.
Make a J-Kwon "Tipsy" station, everyone loves their junior high jams, makes people laugh, gets them dancing.
Or "Shabba" by A$AP Ferg.
Or whatever works for your group. Mindless party rap is your friend though, sets the right mood.
Games
Prep. Prep. Prep.
Flip cup will be good for those who play it... but...
Beer pong is a party center piece, and a great way to pair up with your desired girl. Tell her you have next game and she's your partner, she'll smile and come along.
Have her blow on your ball for luck, bullshit about your amazing abilities (I trained for three years with the beer pong monks in their monastary in the alps, it was rigorous but worth it), make the people laugh.
If you win? great, hold down the table. You lose? Great, girl is paired with you now, go do shots, you have now isolated her, and increased her drunkenness.
Also, buy cards, Circle of Death, Fuck the Dealer, etc. All great chill drinking games.
If you end up with a small, mixed gender group, breaking out a truth or dare app once everyone is drunk is a great way to get people stripping also (either do your dare/truth or take a shot to skip it, people get drunk, then naked)
Your Role
Stay buzzed (NOT DRUNK) and relaxed, keep people happy, start the games. You are a venue now, people are coming to have fun and you have offered to provide it.
Prep
Hide easily walked off with valuables.
Arrange furniture to allow for pong, and atleast one chill area.
If you have a few good bros and female friends to start drinking with before people come, get them. You want people there when people show up.
Expect everyone to show up AT LEAST an hour later than invited.
If you have a buddy with a hookah, have em bring it. Won't stink up your place, but will be a conversation and chill center piece.
Invites
Your current setup is ok, but you should be hustling harder.
Get the numbers of your class's main people. These are the social group centerpieces, where they go, people follow. They'll be the ones talking to people.
Tell your female invites to bring their friends and that everyone is welcome (don't specify gender, just friends, saying bring your female friends sounds desperate, they're girls, they will have girl friends)
Invite outside groups if you really want.
Your closed invite system is good IF they come, but everyone has their standard group they party with, and alot won't come if they can't bring them.
GAME
Your job is to be the alpha party host.
Girls will flock to a well connected dude, if you're a venue host, you live and die by your party.
She will see you as a source of fun and want to secure a spot with the fun.
Your game is getting people in a fun mood, then socializing.
In Case of Cops
Dickhead neighbor calls the police?
Stash the Jungle Juice cooler, have underagers set down their drinks, turn down the music, then open the door and be polite.
DO NOT INVITE THEM IN.
Chances are they will simply ask everyone to leave.
DO NOT MAKE THEM WAIT.
Pissed off cops give out "Distubing the Peace" tickets, and they aren't too bad, but it IS a court date and a pain in the ass.
Social media.
For future endeavors...
Download Erodr, if it is active at your campus.
It's a social media app that requires a .edu email to join. Your posts are only visible to your school and people within like 10 miles of you, and disappear after a day or so (depending on how liked they are).
It's a great spot to advertize and make new connections.
And lastly, have a backup plan. This is your first go, don't be broken hearted if no one shows. It happens to everyone.
Once you're established you can start charging people $5 for a bottomless cup of Jungle Juice and now your house parties are an easy source of profit.
AND DON'T BE AFRAID TO BE OVERT WITH YOUR METHODS.
I've walked too many girls back to my room off "Lemme give you a quick tour of the place so you know where you're at." Then picking them up and throwing them on a bed. (have a couple jokes about the house for the walk, I make jokes about our creepy ass basement)
Also, "lets go throw some fresh coals on the stove for the hookah" is a great separator, if she comes, she likes you. If not, go do it anyways, she was merely invited to enjoy your company while you did your mission.
They came to drink and party with you, all these people are here, you've got pre selection and situation value on lock. Also, every girl in college is a slut. Every. Single. One. (scratch the college, every girl is a slut, period)
They want to fuck, they've been tied down by daddy in highschool, and now they're on their own in college partying, "finding themselves", and riding the damn carousel.
Take advantage of the gift that these circumstances have provided.
If you want to be a party house, and aren't a frat boy, your new job in college is to network EVERY FUCKING WHERE YOU GO.
Download a copy of or buy "Conquer Your Campus" by Mark Redman if you're new to this sort of thing.
Its got a lot of solid stuff in it.
And if no one comes, go hit a club and advertize your place as an after party to girls... you've already go the setup, capitalize and use it.
Good luck and have fun mate.
