The following trick will help you if you don't have much time or you are not making food, or your ovens are full. To perform the glitch you have to put something in front of your Bakery's door like a cash register for example. When the door is blocked nobody can get in so they wont give your bakery a bad star rating. Doing this allows you to level up faster because you won't get bad ratings. When you have sorted out your bakery and are ready for more people put the item blocking the door back to it's place and re-open.
Get many stars
If you want to get a lot of stars 2 boost up you're level then keep or reading this cheat. I have done this many times because I'm trying 2 get a better level than my friend. Okay,now i'll tell you guyz what 2 do. Okay, so, tap on an oven or something 2 cook a food. Choose a food that has alot of stars (XP) the foods that have alot of xp take longer 2 make. But, it's worth it. Pick a food that has alot of coins or stars. (pumpkin pie,choclate tart,espresso.) that will give you atleast 50 stars so you can boost you're level.
Get more neighbors
I don't know if this is a cheat or a tip and trick but, to get more neighbors all you have to do is look at the walls of the bakery's you visit to leave tips. Chances are there are at least a few people (probably more depending on their activity and level) who have left their id on the wall. Just go to your invite tab and enter the id's left on the wall.
Lack of Money
If you don't have much money but have quite a lot of food on your counters go to settings>>>general>>>date and time>>>set date and time>>>skip ahead 2 or 3 days then go back onto the app and all your food would have sold and you will have more money. Then reset the date and time and you can carry on playing the game with no defects.
