While playing, you may have have noticed that there are some bonuses in game. Well, good job. Bonuses are the best way to improve your game.
How bonuses works?
You can play with normal stuff, using your energy everyday, visiting friends, etc. Haven't you thought that the game is a little slow? Actually it is. Require weeks to do what you could do on a few days with bonuses. You can play more, level up faster, and do more quest without even waste anything. That is what bonuses does, if you use them and exploit them properly, you will be buying that item you always wanted, or completing quests faster than your friends.
Let's start with basics.
I'm visiting Bella's house now, and you can see that in the energy bar I have a message that says Bonus 5. This means that I have 5 energy free, to do whatever I want. This will happen with all your neighbors, at least once a day.
USE THAT, IT'S FREE.
You only have 15 energy by your own, but every single neighbours means 5 energy more. Suppose you have 20 neighbors (which is a little amount), so every day you have 100 energy to waste on anything on your neighbors, with 40 neighbors you'll have 200 energy, etc. What I recommend is that every time you need to do something that uses energy, go to your neighbors and use your bonuses. This will give you a lot of free energy (free experience and free simoleons), and allows you to use your energy in your own house, leveling up the skills.
I'll give you more tips on how to maximize the bonuses soon. Good luck!
