Three roles. Two teams. One truth.
Service Rat Roles
Every game of Service Rat deals three hidden roles across two teams. Cats are the majority and know nothing about anyone. Sellouts 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 Sellout 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 Cat
The blind majority. Win by signing five Cat Laws or by kicking the Rat out of town. Your weapons: voting patterns and docket math.

The Sellout
The informed minority. Win by signing six Rat Laws or by getting the Rat elected Ratcatcher at three or more Rat Laws on the board.

The Rat
The hidden leader. Play like a Cat, survive Kick Out of Town, and take the Ratcatcher chair once the board turns against the town.

Service Rat scales from 5 to 10 players. The Rat is always exactly one player; the Sellout count grows with the table.
| Players | Cats | Sellouts | 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 (prerogative timing, the Rat's ally rule, and term limits) see player counts 5 to 10.
Who knows what at role reveal
- Cats see only their own role. Everything else is deduction.
- Sellouts see every other Sellout and the Rat.
- The Rat sees his one Sellout ally in 5–6 player games; in 7–10 player games, the Rat sees no one.
