Prime Suspect — A card game of bluffs and deduction — play solo against bots or with friends
Prime Suspect is a strategic card deduction game. Play solo against smart bot opponents or challenge up to 4 friends online. Same draw-one-play-one structure as Love Letter, with a detective theme.

You collect tokens across rounds to win the match.

How to Play Prime Suspect
- The 8 card types (1-4) — Inspector (1): Name a number 2-8; if a player holds that card, they are eliminated. Butler (2): Secretly look at another player's card. Witness (3): Compare cards with another player; the lower number is eliminated. Lawyer (4): You are immune to all card effects until your next turn.
- The 8 card types (5-8) — Blackmailer (5): Force a player to discard and draw a new card. Double Agent (6): Swap your card with another player's. Accomplice (7): You must discard this if you also hold the Blackmailer or Double Agent. Murderer (8): Highest value, but if this card is ever discarded, you are out.
- Play a round — You start with one card. On your turn, draw one from the deck so you hold two, then play one face-up and resolve its effect. Use card abilities to figure out what others hold and knock them out.
- Win the round — A round ends when one player remains (they win) or the deck runs out (highest card number wins). The round winner earns a token.
- Win the match — Collect enough tokens to win: 7 for a 2-player game, 5 for 3 players, 4 for 4 players.

Draw a new card each turn, play one, and use its effect to gather intel, eliminate opponents, or protect yourself. Deduce what the others are holding. Accuse, protect, spy, and bluff your way to the truth.

Frequently Asked Questions
Can I play alone?
Yes! Add bot opponents in the lobby and play solo. Bots make smart, human-like decisions using game knowledge.
Is Prime Suspect similar to Love Letter?
Same draw-one-play-one structure as Love Letter, with a detective theme. The eight card abilities map to Love Letter's roles with different names.
How long does a game take?
Individual rounds take 2-5 minutes. A full match (collecting all required tokens) takes about 15-30 minutes depending on player count.
What happens if I discard the Murderer?
You are out of the round. The Murderer (8) is the highest-value card, but if another player forces you to discard it via the Blackmailer, you lose.
Can I play with just 2 players?
Yes. Prime Suspect plays well with 2 players (first to 7 tokens). It also works with 3 or 4 with adjusted token targets.
