The best murder mystery games for 2 players
Short answer: INQUEST is the pick built specifically for real-time two-player co-op online. You and a friend open the same case at the same time, free to start, no sign-up, no app to install. The rest of this list covers what else holds up as a duo, and how each one actually plays in practice.
Two-player whodunits are a small, oddly underserved corner of the genre. Most mystery games assume you play solo or as a party of six. If you’re a duo and you want to spend an evening solving a case together, here’s the short list of what actually works, plus how each one feels in practice.
What “two-player murder mystery” really means
Three shapes show up:
- Shared screen, one detective. You play together at one device, talking through clues. Fine for the couch. Bad if you’re in different rooms.
- Same case, two devices. Both of you load the same case independently and compare notes over chat or call. Works remotely, but the game doesn’t know you’re a pair.
- True two-player co-op. Both of you connect to the same case, see the same dossier, and the game knows there are two detectives. You can split the interrogation, argue the timeline, and submit your own accusation.
The third shape is the rarest and the most fun. It’s also what INQUEST does.
Picks
INQUEST. Built specifically for solo or two-player co-op. You and a friend open the same case at the same time over a peer-to-peer connection. You share the dossier and the chat, but each of you makes your own final accusation. The disagreements are half the fun. Free to play at playinquest.com/play.
Sherlock Holmes Consulting Detective. Classic, slow, casebook-style. Easy to play as a duo over a video call: one person reads the prompts, both of you talk through where to go next. No mechanical two-player mode, but it suits a pair better than a party.
Mysterium. A board game first, with a digital companion app. Asymmetric: one of you is the ghost, the other is the medium. Different from a classic whodunit, but a strong duo pick if you want something cooperative-ish that isn’t both of you on the same side.
Return of the Obra Dinn. Single-player by design, but a famously good “pass the controller” game. One person drives, the other reads the manifest and shouts theories. It works.
The Case of the Golden Idol. Same shape as Obra Dinn for couch co-op. Hand the device back and forth, argue, redo.
How to set up an online co-op evening
The most common version of this: two people, two devices, not in the same room, solving one case together over a video call (FaceTime, Discord, Zoom, whatever you already use). INQUEST doesn’t run the call itself, it just needs to know you’re a pair, so here’s the setup:
For INQUEST specifically:
- One of you opens the game and creates a co-op room. You’ll get a room name and a four-digit pin.
- Share the room name and pin with the other player however you’d normally chat.
- They join the same room. You’re now both in the same case.
- Start your video or voice call on the side, then use the in-game chat for anything you want on the record. The game doesn’t care which one you use for the actual arguing.
For any other game in this list, open a voice call, share the screen if you can, and decide upfront whether you’re both reading or one person is driving.
Why pairs solve these better than groups
A party of six picks a killer by vote. A pair has to actually agree, and disagreement is the engine of a good mystery. If you and your partner read the same alibi and walk away with different theories, you’ll dig into it. That’s the whole experience. Groups skim. Pairs argue.
If you also (or instead) want to solve cases alone, the best detective games to play right now is the solo equivalent of this list. And if you’ve been spending on Hunt A Killer, the cheaper alternatives are worth a look.
