Idle Mafia Game Big Update 3: Start Time, Countdown & What’s Coming

Idle Mafia Game keeps its community fed with a steady run of Big Update drops, and Big Update 3 is the next one up. These releases arrive on a fixed schedule rather than at random, which is why the game — sitting on about 3,800,000 lifetime visits and drawing about 6,800 players at any given moment — has built a habit of bosses checking back around each one.
The Big Update isn’t a one-off. Stacks of Cash pushes a fresh one roughly every ~3 days, so there’s always another on the near horizon. Big Update 3 is scheduled for Thursday, September 10 at 5 PM ET — the exact start time and the usual weekly windows are on the card below.

How often updates land, and when
A new Big Update lands roughly every ~3 days. In practice that settles into two slots a week: Mondays at 5:00 PM ET and Fridays at 4:00 PM ET. Two windows give players scattered across the world’s time zones more than one chance to be online when a drop goes live — a Monday-evening release in New York falls in the small hours across Asia, while the Friday-afternoon slot tends to sit more conveniently there. The developer has run this rhythm 2 times so far.
Here is how the two weekly windows convert across the major regions:
| Region | Monday window | Friday window |
|---|---|---|
| US Eastern | 5:00 PM Mon | 4:00 PM Fri |
| US Pacific | 2:00 PM Mon | 1:00 PM Fri |
| UK | 10:00 PM Mon | 9:00 PM Fri |
| Central Europe | 11:00 PM Mon | 10:00 PM Fri |
| India | 2:30 AM Tue | 1:30 AM Sat |
| Japan | 6:00 AM Tue | 5:00 AM Sat |
| Australia (AEST) | 7:00 AM Tue | 6:00 AM Sat |

How it fits Idle Mafia Game’s rhythm
The Big Update is the centerpiece of Idle Mafia Game’s release calendar — the recurring beat the rest of the game’s activity tends to orbit. With drops arriving about twice a week, it’s the most dependable reason to keep the game in your rotation, and the clearest signal of where Stacks of Cash is taking it next. As of September 9, the Monday and Friday cadence is holding steady.
