There's a lot of requests on Expert without Bonuses so here's a guide compiling some of the tips people have shared here.
1. Reset Early for Good RNG
You're not guaranteed to succeed each run. The requirements for satisfying a client are much higher in this mode and can reduce how much you earn to as little as 5%. It's important to get a good start so keep resetting until you can find a good set of clients that can be satisfied by Harpy and Werewolf. SAVE AFTER FINDING THE RIGHT CLIENTS (3 WITH MATCHING FETISHES/VIRGINS). Buy your girls and start reloading the End Phase until you can get a $30K+ night. You can refresh the Market by leaving and coming back in case you need a duplicate or a specific girl.
2. Girls are Disposable
Early on you can't afford to train a girl to match your clients' Desired Type. Check your Clientele each night and buy from the Market based on their fetishes. Sell off girls after expending their Virgin status, Virgins offer a 50% Satisfaction Bonus so use that to squeeze as much profit from each girl. Avoid using items on girls until you're comfortably over quota or have plenty of time to match quota after. Week 3 onwards (Mid-Week 2 if you're lucky), you can start to keep and train girls to match Desired Type.
3. Use Escorts for Quick Money
Escorts are a great way to earn profit quick and clear space for new girls. Week 1 Escorts will always be the same each run and won't change until you refresh or complete an Escort. Long Period Escorts (Pink Escorts) are not worth trying for early on and only pay out after the Escort is completed. To train each Week 1 Escort, do the following:
Harpy - Buy Day 3, Max Cunnilingus, End Phase, Lay Egg, Missionary until Base Lv 2 LWD
Werewolf - Buy Day 3, Max Nipples, End Phase, Facefuck until Lv 3 OBD
Myconid - Leave Alone, End Phase, Spanking until Lv 3 LWD
If you can afford to, get the Tool Cleaning Room for improved Training
4. Don't Forget to Train
While training girls can be counterproductive when you're selling them off the next day, training will level up your own Training Level. The higher it is for each style, the easier it'll be to match girls for Clients or Escorts. When trying to match stats, try to train on Full Moons or with Aphrodisiac if you can afford it or got lucky from your Myconid. The first Full Moon is Day 4 and will put all girls into heat, but girls bought on Day 4 will not go into heat. Plan accordingly!
5. Level your Club quick
Higher level club means better girls and more training actions. Draining Clients will net more Club Stars so drain where you can.
6. Priority Girls
There are 3 girls with abilities that can drastically ease the difficulty of your run.
- Oni
Unlocked at Rank 3 for $10K. Her Fortune Summoner ability can replace a client with Wealthy one instead. Use it for extra profit or reroll annoying clients (STD/Rough/Playboy/Unavailable Fetishes). The ability is exchangeable so feel free to transfer it to another girl if you want.
- Dark Fairy.
Available for Auction on Day 12, Cheapest bid $15K. Great support girl, not so much for prostitution. Training with her can get you Fairy Dust to make non-sprite Training better. If you commit to training her to Lv 3 AFF, OBD and LWD, you can unlock her Fairy Secretions to recover Training Actions once a day. Only Onahole Style will activate this ability and can't be exchanged.
- Kraken
Available for Auction on Day 15, Cheapest bid $20K. Melody of the Sea can reset Wait Time during the Prostitution Phase, perfect for matching clients with the right girl and clearing as many clients as possible. Stronger clients can leave a girl out of commission for the rest of the night so be ready to use it. Full Moons also reset her Virgin status so you can earn extra on those nights.
7. Priority Upgrades
There's only a few upgrades worth getting early if you can afford it. Entrance Ad Sign, Suite Room, PR Room, Tool Cleaning Room and Slave Rooms. Maximizing Profits or Efficient Leveling will get you far enough that you can start to afford to keep and train girls.
Once you're past Week 3, congratulations you're past the hard part. Buy and train whoever you want. Get the Angel on Day 21 to get a hyper carry if you want an even easier time.
