The Mafia Boss (TMB) is a free, browser-based multiplayer online mafia strategy game that has been running since 2004. With over 2 million registered players worldwide, it is one of the longest-running browser games of all kind. No download required — play from any device directly in your web browser.
Yes, The Mafia Boss is completely free to play. You can sign up, build your criminal empire, join a family, and compete for prizes without spending a single dollar. Optional supporter packages are available to enhance your experience but are never required to be competitive.
Each round lasts approximately 10 days. At the start, all players begin with equal resources. You spend the round committing crimes, building your army, attacking rivals, and accumulating net worth. At the end, in-game credit prizes are distributed to the top-ranked individual players and families.
There are three main competitive roles: Killer (ranked by kills — attacks enemies for kills), Looter (ranked by looted cash — attacks for money), and Collector (ranked by net worth — accumulates resources without direct fighting). Each role requires a different strategy to reach the top.
Families are groups of players that compete together as a team. You can join a family by accepting an invite from a Don or by applying to open family. Families coordinate attacks, share strategies in the family chat, and compete for the top family prize at the end of each round. A Don and Underboss lead the family structure.
At the end of each 10-day round, top-ranked players and families win in-game credit prizes — the premium currency that powers faster progress in future rounds. Prizes are awarded across multiple categories (networth, kills, and families), so there are many ways to win.
Turns are your primary resource — they power every action (crimes, attacks, scouting, producing). You receive turns automatically over time. You can also earn bonus turns by committing crimes, buying turns with credits, or receiving turns from your family. Using turns efficiently is the key to success.
