When building your Top Mafia, put a Fearless character in the Wheelman position (the higher the level, the better) to use up to 11% less energy when doing jobs. This also increases your chances of completing jobs without using any energy.
-Use your energy on jobs. If you want to level up, use the lowest amount of energy to gain the most experience points. Use the remaining energy points for other jobs that you have yet to master.
-As your Mafia List grows, friends and contacts will send updates to your Facebook wall asking for help with their jobs. You have a limited time before others help (up to 25 friends can accept the offer). Helping will earnyou several experience points for a small amount of effort.
-When building your Top Mafia, choose one of your mafia who has completed the most jobs to be your top mastermind. This gives you a higher level of experience per job.
-Looting increases your defense and attack scores. The odd items you get are usually part of a collection. When you gather all seven of the odd items in a collection and vault it, you will get an experience bonus.
-Note: This require higher level players. The Hitlist is where players place a bounty on other players. It's possible to gain up to 44 experience points for being on a Hitlist. Note: Teams will change their character's status name to something that makes them seem weaker.
For lower level players, fights are vital. Since they only offer between 1 to 6 experience points per stamina point, fights don't really help you to level up. However, for players with a lot of stamina points and health (or money to heal), fights can help make a big difference. Note: If you fight too much or keep hitting the "Fight Again" button, you will make enemies. If they snuff you, you can lose just as many experience points as you gained.
