Service Rat

Q: How many players does Service Rat support?

Service Rat supports 5 to 10 players. Role distribution scales automatically: a 5-player game has 3 Workers, 1 Saboteur, and 1 Rat; a 10-player game has 6 Workers, 3 Saboteurs, and 1 Rat. Bot players fill any open slots so you can play with fewer humans.

Q: What happens after three failed votes in a row?

Three consecutive failed nominations trigger Chaos on the Floor. The top blueprint from the draw pile is automatically enacted — bypassing both CEO and Chief Engineer — the downtime tracker resets to zero, and play continues. Saboteurs deliberately block votes to trigger this when the draw pile is stacked in their favor.

Q: What is Veto Power and when does it unlock?

Veto Power unlocks after 5 Sabotage blueprints are enacted. Once unlocked, the Chief Engineer may request a veto before implementing a blueprint. The CEO can approve — discarding both blueprints and advancing the downtime tracker by one — or deny, forcing the Chief Engineer to implement one of the two blueprints as normal.

Q: What multiplayer modes does Service Rat have?

Service Rat has three multiplayer modes: Pass and Play (one device passed around the table), LAN Multiplayer (all players on the same Wi-Fi, each on their own device), and Online Multiplayer (share a room code and play from anywhere). All three modes are free and require no account.

Roles

Three roles.
One truth.

Service Rat is a free mobile social-deduction app for 5 to 10 players, inspired by the Secret Hitler board game. The phone handles everything: it deals hidden roles, runs votes, applies directives, and AI bots fill empty seats — so there is no moderator and no need for physical cards. Three play modes are included: pass the phone around one device, LAN multiplayer over local Wi-Fi, and global online multiplayer via a shared room code. The Worker team wins by enacting five Modernizations or by Terminating the Rat; the Saboteur team wins by enacting six Sabotages or by electing the Rat as Chief Engineer once three Sabotages are on the board. Service Rat runs on Android and iOS, requires no account, collects no personal data, and is the closest native-mobile alternative to secrethitler.io and the boxed Secret Hitler when you have a group but no cards or moderator.

The deck is intentionally biased against Workers. Without strict oversight, Sabotage is inevitable.

Worker

Labor for the good of the plant

Goal: Implement 5 Modernization blueprints or Terminate the Rat. You don't know who is sabotaging the work - rely on behavior and voting patterns.

Saboteur

Time to break the machines

Goal: Implement 6 Sabotage blueprints or appoint the Rat as Chief Engineer. You know the other Saboteurs and the Rat - but blend in.

The Rat

The secret leader of dissent

Goal: Bankrupt the company. You know you are the Rat — but you do not know who your Saboteur allies are. If 3+ Sabotage blueprints are on the board and you become Chief Engineer — your team wins instantly! Avoid Termination!

Blueprint Deck

17 blueprints.
Two agendas.

The CEO reviews 3 blueprints each shift, discards 1, and passes 2 to the Chief Engineer, who implements 1. Watch what gets enacted.

Modernization - 5 needed

Workers win at 5 Modernizations

Sabotage - 6 needed

Saboteurs win at 6 Sabotages

Shift

Shift Formation Phase
+ Production Cycle.

Each round is called a Shift. Three failed shifts trigger Chaos on the Floor - a blueprint is auto-implemented and the downtime tracker resets.

Appointment

The current CEO nominates a candidate for Chief Engineer. Term-limited players are ineligible.

General Meeting

All players vote. Majority required to pass. A tie results in failure. Three consecutive failures trigger Chaos on the Floor.

Blueprint Archive

The CEO draws the top 3 blueprints, secretly discards 1, and passes the remaining 2 to the Chief Engineer. You can lie to them.

Chief Engineer's Workshop

The Chief Engineer chooses 1 of the 2 blueprints to implement. The other goes to the shredder. Veto Power may be requested if unlocked.

CEO Directive

Certain Sabotage milestones grant the CEO special authority. The directive is used immediately after the blueprint is enacted.

CEO Directives

Executive authority
grows with decay.

Directives unlock as Sabotage blueprints accumulate. Exact thresholds vary by player count — in a 5-player game, Personnel Audit unlocks at the 1st Sabotage blueprint; in a 9–10 player game, players reach Termination at the 4th. Each directive is used immediately after the blueprint that triggered it is enacted.

🔍

Personnel Audit

The CEO secretly checks a player's file - Worker or Saboteur. Each player can only be audited once. You may lie about the result.

📋

Blueprint Preview

The CEO secretly examines the top 3 blueprints in the archive. You can lie about what you saw to derail the next shift.

⚡

Extraordinary Shift

5	3	1	1
6	4	1	1
7	4	2	1
8	5	2	1
9	5	3	1

Win Conditions

Four ways to win.
One game.

Service Rat ends the moment any of these four conditions is met. Most games last 20–35 minutes for a 7-player table.

🛠️

Workers — Modernize

Enact 5 Modernization blueprints. The deck only contains 6, so coordination matters.

🚫

Workers — Terminate the Rat

Use the Termination CEO Directive to remove The Rat. Game ends instantly.

⚙️

Saboteurs — Sabotage

Enact 6 Sabotage blueprints. The deck is biased toward Sabotage with 11 such cards.

🐀

Saboteurs — Elect the Rat

Get The Rat appointed Chief Engineer when 3+ Sabotage blueprints are already enacted. Instant win.

Strategy

How to play
each role.

Service Rat is solvable, not random. Each role plays a different angle — here is how to win at each.

Strategy: Playing the Worker

Workers are the majority but cannot prove who is who. Your real job is pattern recognition: who votes No on every nomination? Who pushes a Chief Engineer that Saboteurs would love? When you are CEO, nominate someone you would bet your shift on. When you are Chief Engineer, study the two blueprints the CEO hands you — if the draw pile is clean and you still get two Sabotage cards, the CEO is lying. Save your Blueprint Preview directives for shifts where the result will change votes, and remember exactly who you audited. Saboteurs survive on ambiguity; your weapon is making the record concrete.

Strategy: Playing the Saboteur

Saboteurs win by quietly steering the Modernization track into the dirt. Do not out yourself early — vote Yes on questionable nominations in the first two shifts to look reasonable, then drop the hammer mid-game when the deck is stacked. As CEO, hand the Chief Engineer two Sabotage blueprints whenever you can, and always have a believable story about what you discarded ("I had to keep one Modernization back, the deck was bad"). Always know who The Rat is, never name them, and protect them when a Termination directive comes up. The longer you stay in the shadows, the harder Workers find it to track suspicion.

Strategy: Playing The Rat

Your win condition is conditional and you do not know your allies. Until 3 Sabotage blueprints are enacted, play exactly like a Worker — vote conservatively, build trust, accept Chief Engineer nominations that look harmless. Once the Sabotage track crosses 3, your job becomes "get appointed Chief Engineer" instead of "blend in". Lean into players you suspect are Saboteurs and let them nominate you. Avoid drawing suspicion at any cost: if Workers reach Termination and pick you, the game ends in your loss. Trust no one. Especially the loudest voice at the table — that confidence is often a tell.

Comparison

How Service Rat compares
to other deduction games.

If you have played Secret Hitler, Mafia, Werewolf, or Among Us, you already know most of the mechanics.

Service Rat: A Mobile Alternative to Secret Hitler

Service Rat uses the same core mechanic as Secret Hitler: players nominate a two-person government (CEO and Chief Engineer), vote to approve it by majority, and the approved government draws blueprints from a biased deck — the CEO discards one, the Chief Engineer enacts one. The key differences are theme, format, and platform. Service Rat replaces the political setting with a corporate one, using original role names (Workers, Saboteurs, The Rat, CEO, Chief Engineer) that are suitable for any audience. The game is entirely digital — no physical cards, no printing, no moderator required. It runs natively on Android and iOS and adds three built-in multiplayer modes (Pass & Play, LAN, and Online), AI bot opponents with suspicion modeling, and a post-game statistics screen. The original Secret Hitler has no official mobile app. Service Rat is free to download on both platforms.

Service Rat vs Mafia / Werewolf

Service Rat differs from Mafia and Werewolf in three fundamental ways. First, there is no human moderator — the app assigns roles secretly, tracks hidden information, and enforces all rules automatically. Second, there are no nightly eliminations. The only way to remove a player is through the Termination CEO Directive, which is unlocked only after enough Sabotage blueprints are enacted. Third, tension is built through a legislative track rather than accusation and vote-to-eliminate. Every blueprint enacted narrows down who is likely a Saboteur, creating a persistent, verifiable evidence trail — votes, enacted blueprints, directive outcomes — that all players can reference and dispute across the entire game. Service Rat works on a single shared device in Pass & Play mode, making it practical for groups that do not want everyone on their own phone. Free to download on Android and iOS.

Service Rat vs Among Us

Service Rat and Among Us are both social deduction games where a hidden minority deceives a majority, but they are structurally different. Among Us is real-time: players move through a map, complete tasks, and call emergency meetings when they spot the impostor. Service Rat is fully turn-based with no movement — every action is a vote or a blueprint choice. Both games require 5 to 10 players, but Service Rat can fill empty seats with AI bots, so a group of 2 or 3 humans can still play a full game. Service Rat also works in Pass & Play mode on a single shared device; Among Us always requires one device per player. The key mechanical difference is that Service Rat creates a persistent, public evidence trail — every enacted blueprint, every vote, every directive result — that all players can reference and argue over throughout the game. Free on Android and iOS.

Service Rat vs Werewolves of Miller's Hollow

The Werewolves of Miller's Hollow uses 16+ role cards (Seer, Witch, Hunter, Cupid, Thief, etc.) and a 30+ minute game scales to 4–50 players via expansions. It requires a dedicated Narrator who memorizes the script and reads each night phase aloud. Service Rat has only 3 roles (Worker, Saboteur, The Rat) and a fixed 5–10 player range — and the app fully runs the game with zero memorization. The night-action Seer / Witch / Hunter mechanic becomes the in-app Personnel Audit, Blueprint Preview, and Termination directives, surfaced as the Sabotage track advances. No Narrator burnout, no role-card lookups mid-game, and AI bots can fill any seat if you are short a player.

For Secret Hitler fans

Looking for a
Secret Hitler app?

Service Rat is a free mobile game inspired by Secret Hitler, available on Android and iOS. The original Secret Hitler is a print-and-play board game with no official mobile app — only browser-based clones exist. Service Rat brings the same hidden-role legislative mechanic to a native mobile experience: secret factions, government nominations, biased card draws, and the same tense voting dynamic.

The theme is corporate instead of political, and role names are original — but if you have played Secret Hitler, you already know how to play. Three multiplayer modes (Pass & Play, LAN, Online) work on a single phone or across devices. AI bot players fill empty seats. No printing, no setup, no account.

Free on Google Play and the App Store.

FAQ

Common questions
from the floor.

Everything a new employee needs before their first shift.

How many players does Service Rat support?

Service Rat supports 5 to 10 players. Role distribution scales automatically: a 5-player game has 3 Workers, 1 Saboteur, and 1 Rat; a 10-player game has 6 Workers, 3 Saboteurs, and 1 Rat. Bot players fill any open slots so you can play with fewer humans.

Is the full game really free?

Yes. All game modes — Pass & Play, LAN, and Online — are free. Optional in-app purchases include a one-time Remove Ads upgrade and a Tip Jar for players who want to support development. Nothing is paywalled.

How is Service Rat different from Secret Hitler?

Service Rat is a free digital adaptation inspired by Secret Hitler, set in a failing corporate enterprise. The core mechanic is identical — hidden roles, shared card draws, social deduction — but Service Rat is free, runs on Android and iOS, supports AI bot opponents, and offers three distinct play modes. No printing or cards required.

Can I play with fewer than 5 people?

Yes. Bot players fill any empty slots. You can start with 1 human and 4 bots. The bots score suspicion based on voting history and shift records — they will call you out if your legislative choices look suspicious.

Does online multiplayer require an account?

No. The host creates a room and shares a code. Anyone with the code can join. No email, no registration, no tracking.

What happens after three failed votes in a row?

Three consecutive failed nominations trigger Chaos on the Floor. The top blueprint from the draw pile is automatically enacted — bypassing both CEO and Chief Engineer — the downtime tracker resets to zero, and play continues. Saboteurs deliberately block votes to trigger this when the draw pile is stacked in their favor.

When exactly does the Rat win?

The Rat's team wins if 6 Sabotage blueprints are enacted, or if the Rat is elected Chief Engineer when 3 or more Sabotage blueprints are already on the board. Simply being nominated is not enough — the Rat must take the Chief Engineer seat at the right moment. Workers win by enacting 5 Modernizations or by Terminating the Rat via a CEO Directive.

What is Veto Power and when does it unlock?

Veto Power unlocks after 5 Sabotage blueprints are enacted. Once unlocked, the Chief Engineer may request a veto before implementing a blueprint. The CEO can approve — discarding both blueprints and advancing the downtime tracker by one — or deny, forcing the Chief Engineer to implement one of the two blueprints as normal.

What multiplayer modes does Service Rat have?

Service Rat has three multiplayer modes: Pass and Play (one device passed around the table), LAN Multiplayer (all players on the same Wi-Fi, each on their own device), and Online Multiplayer (share a room code and play from anywhere). All three modes are free and require no account.

Is there an official Secret Hitler mobile app?

Not for the main game. The publisher Goat Wolf Cabbage released an official Companion app (narrated by Wil Wheaton) that handles the night phase — but you still need to own the physical board game to use it. Various third-party browser games exist (secrethitler.io, secret-hitler.online) and a paid third-party Android app under the Secret Hitler name, but none are officially endorsed by the original creators. Service Rat is a free native mobile alternative built ground-up for Android and iOS — same hidden-role legislative mechanic, original corporate-themed roles, no political content, Pass & Play on one device, plus LAN and online multiplayer without an account.

Is Service Rat appropriate for all ages?

Yes. Service Rat is rated Everyone on Google Play and 4+ on the App Store. The theme is a failing corporate enterprise — there is no political content, no violence, no objectionable language, and no in-game chat. Suitable for family game nights, school clubs, and workplaces.

How is Service Rat different from the Secret Hitler Companion app?

The official Secret Hitler Companion app (Wil Wheaton narrator) is a night-phase reader — it requires you to already own the physical Secret Hitler board game, distributes roles via the app, and narrates the night. The actual game still uses physical cards on a table. Service Rat is the opposite approach: a complete native game. No physical components needed, no card shuffling, the app simulates the entire blueprint deck and runs every game mode (Pass & Play, LAN, Online). You can also fill any open seat with an AI bot — useful if you have 4 humans but need 5+ players. Free, no account, runs offline in Pass & Play.

How long does a Service Rat game take?

A typical 7-player game runs 20 to 35 minutes. 5-player games can finish in under 15 minutes; 10-player games can stretch to 45 minutes when nominations are heavily contested. Pass & Play games are slightly longer than LAN or Online because of the device handoff between players.

What languages does Service Rat support?

Service Rat is fully localized in seven languages: English, Russian (Русский), German (Deutsch), Spanish (Español), French (Français), Portuguese (Português), and Ukrainian (Українська). Both the in-app text and the marketing site are available in all seven, and the language switcher is in the top-right corner of every page.

About

Made by one person.
Tested by many.

I built Service Rat because every time my group wanted to play Secret Hitler, someone forgot the cards or we needed a moderator. iEDZ — the sole developer — wrote the game in Kotlin Multiplatform and Compose Multiplatform so it runs natively on both Android and iOS from a single codebase. The bot AI uses suspicion modeling from shift history, not random chance.

The project is actively maintained. Bug reports and feedback are welcome at [email protected].

What's new · Version 1.3.1

Stability improvements, bug fixes, refined permission handling, and quality-of-life polish across all multiplayer modes. Released May 2026.

Service Rat is not affiliated with or derived from any licensed property. It is an original social deduction game with a corporate theme, free to play on Android and iOS.
