Here are a couple of pro tips I can throw for beginners:
- Day 2 is always the game definer for me: Buy a Hippie (4) - If there isn't a Hippie, wait for Day 3 for a cute Dog or a Counselor. If there is no trouble mitigation AT ALL (it happens) get the guys who kick people out + Taxi drivers + Private II + Cupid.

Trouble Mitigation is your priority.

2) Right after that, focus on the economy to make the house as big as possible as soon as possible.

3) Try to look for Popularity combos:

- If there isn't much trouble mitigation, Introverts will make your life easier. (wrestlers go well with them)
- 4 Dancers is always a good party
- A comedian is always a good choice if you have ZERO trouble issues, you need the economy for it, or you will end up with a pretty small house.
- Stylist + Cheerleader are an easy win if you can get an excellent economy popping off.
- Troublemakers + Hippies + cute dogs + Bartenders + Writers always go well together.
- If you have a big house by, let's say...15-12 days left to go, get the Climber train going.
- Mascot + Old Friends.

4) Last but not least, and I can't stress this enough.

***** ALWAYS PLAY IT SAFE *****

You'd rather get let's say 4 pop and 1 cash rather than 0. This can make the difference between winning and losing early on.

Only go for the "All in" if you REALLY need it. Or you are just a gambling addict; it's your choice.
