Don’t be a quick fighter

You can achieve a lot of experience from winning fights but they can cost you in other ways. For example if you are snuffed out in a fight you lose some experience. You should avoid fights and focus on completing as many jobs as possible to help you level up quickly. Once you have built up a larger and solid organisation you can fight to your hearts content.

The Importance of your Top Mafia

It is important to promote a strong top Mastermind as quickly as possible since it will improve your ability to level up fast. It will enables you to earn more experience points from all the jobs you complete. Also have a good wheelman recruited since it will help you to complete more jobs with less energy needed.

Jobs with a good return

You should work on jobs which give you the biggest return in terms of experience points for the energy required. There are many ways to generate cash in the game so you shouldn’t worry about that here.

The faster you can accumulate experience means you’ll level up faster and will have more energy available to continue doing jobs and making money

Maximize Your Energy

Each time you master a job or level up, you are given skill points which can be used to improve your character. Use these skill points to increase your maximum energy. Without this energy there isn’t much you can do in the game. The more energy you have, the more jobs you can complete. This gives you experience points.
