Three roles. Two teams. One truth.
Service Rat Roles
Every game of Service Rat deals three hidden roles across two teams. Workers are the majority and know nothing about anyone. Saboteurs are the informed minority: they see each other and they see the Rat. The Rat is the hidden leader the whole game revolves around - in a 5–6 player game the Rat learns his single Saboteur ally at role reveal, but from seven players up the Rat knows no one at all. Who knows what is the entire game; pick a role guide below to learn how to play it.
The Worker
The blind majority. Win by enacting five Modernization blueprints or by terminating the Rat. Your weapons: voting patterns and deck math.

The Saboteur
The informed minority. Win by enacting six Sabotages or by getting the Rat elected Chief Engineer at three or more Sabotages on the board.

The Rat
The hidden leader. Play like a Worker, survive Termination, and take the Chief Engineer chair once the board turns against the company.
Rat guide →Role distribution by player count
Service Rat scales from 5 to 10 players. The Rat is always exactly one player; the Saboteur count grows with the table.
| Players | Workers | Saboteurs | The Rat |
|---|---|---|---|
| 5 | 3 | 1 | 1 |
| 6 | 4 | 1 | 1 |
| 7 | 4 | 2 | 1 |
| 8 | 5 | 2 | 1 |
| 9 | 5 | 3 | 1 |
| 10 | 6 | 3 | 1 |
Don't have a full table? AI bots can fill any empty seat, so one human plus four bots is enough to start a 5-player game. For a deeper look at how each size plays — directive timing, the Rat's ally rule, and term limits — see player counts 5 to 10.
Who knows what at role reveal
- Workers see only their own role. Everything else is deduction.
- Saboteurs see every other Saboteur and the Rat.
- The Rat sees his one Saboteur ally in 5–6 player games; in 7–10 player games, the Rat sees no one.
