Cash is a very important resource that has many uses in-game:
- Upgrading buildings.

Cash can be acquired several ways in-game:
- From buildings.
- From the cash transit van that can occasionally be found driving through the streets
- From the Shop (can be bought with Diamonds).
- From some Arena rewards.
- From Login Calendar.
- From Team Fight.

Whenever you've been away from the game for a while and come back, you will see an option to watch a video and double your Cash income.

Tip: get the Mafia Club Membership and you can skip watching these videos but still get the Cash.
