Just a little tip for the beginning. Take all the money from the loan shark and buy upgrades and supplies. No advertising at the moment. Let one day p and the Fairy godmother will give you a second chance and pay the loan shark. Now you can loan money again and spend some in advertising and research. Its good to have the potion-research ready before your opponent. You can sell the potions for high prices cause you are the only one with this potion at the moment. A combination of the mole-spy and the magic ink spell is useful. Hire the mole start the day and use the magic ink to controll the prices of your opponent. If you only hire the mole you get the prices of the last day not the actual standart.
This tactic helped me until the last level, this one is a little bit harder to win, just trying. :o)

When you get the random adventures play them, if you send them away you will lose the chance of getting some money.
Here some short advices for some of the adventures.
Bad Hare day: Believe the hare, call the tortois, Ask the tortois about the racing day, test the lotion in the lab, after some day you get the resaerch that it is only sun lotion, call the hare again, ask him about the racing day, ask him about the wolves, ask him about the sport drink, choose the wolfes were betting on the tortois, you will gain some popularity

The three pigs: Help the pigs with suggesting the should use bricks, loan them the money they need, after some days you can choose between the money back or a free shop upgrade

Red riding hood: Suggest it could be a genetic problem, suggest it could be a wolf, ask to meet grandmother, after some days the grandmother appears, ask her about her teeth, ask her the other questions, let her go, wait the moonlight?, grandmother is a werwolf, tell red riding hood grandmother is a werwolf, some days later you will recieve some extra beans from red riding hood

The giant baker: ask him about his recepie, ask him about the grindet bones, tell him not to kill his costumers, tell him to use sourdough, some days later you will recieve some golden eggs (250 Beans)

The Biker story: Hear both sides of the story, suggest they should work together, suggest the girl should make a dinner for the bikers guests, suggest nachos, some days later you will recieve some beans as reward

Cinderellas Stepsisters: Ask what the want, hear through the story, suggest to talk to cinderella, tell her to let the stepsisters go to the ball, tell her she is to beautifull for the ball, some days later you will get a free shop entertainment update (better upgrade it a day before, could save some money later) :o)

The Not so handsome prince: Hear his story, arrange a date with cinderellas stepsister, some days later he will bring you 500 Beans as reward

The ugly Swan: Tell her she is a swan, next time she arrives make her a beauty potion, some days later she will come back and reward you with some beans

The Bearzinis: You can't reject the invitation but make sure to leave the after you wonder were goldilooks could be, you will find her stealing your supplies but she drops a lot of the on the run

Same thing with the Sneerguy, you cant refuse his offers but you can look that he does as little damage as possible. First time he will damage your resaerch, make sure you have closed your research until he cames in and nothing will happen. Next time he will steal some money. The third time let your pixies watch over him. If you fire him in an instant it costs you money and when you go to the court it will also cost you reputation.

Hope this will help a little bit on your way
