The case: Last One Screaming
Hollow Pines was supposed to be one last Halloween blowout: six college friends, a rented lake house deep in the woods, and a fake "masked killer" stunt they planned to film for their channel. Then the lights cut out for real — and when they came back, host Derek Callahan was dead by the fireplace, killed with a real blade someone swapped in for the harmless prop.
The group blames the local legend, the Hollow Man. The evidence says otherwise: the doors were locked from the inside, the breaker was cut by hand rather than tripped, night-vision footage catches a left-handed killer, and a forgotten kitchen camera puts one friend somewhere they swore they never went. Untangle the staged scares from the genuine crime — and name the killer before the last one screaming is one of you.
How it plays
One person starts a room in the browser and shares the link or QR code. Everyone joins from their own phone, tablet, or laptop — no downloads, no accounts needed for guests. Evidence drops in stages so different players catch different details. Examine evidence on a shared board, interview suspects, debate the timeline, and submit your accusation.
Built for Halloween parties — in person and virtual
- Best with 2–8 players; rooms support 20 total including the host. No One Leaves Unmasked is designed for 1–6 detectives. Bigger parties can run parallel rooms and compare verdicts.
- Virtual Halloween party ready. Everyone joins from their own browser over any video call — Zoom, Meet, Teams. The game handles the evidence board; your call handles the banter.
- Great for office Halloween parties. Browser-based, no installs, no IT approval needed. Run parallel rooms for bigger groups and compare verdicts at the end.
- Spooky atmosphere, no gore. A dark lake house, a prank gone wrong, suspects who are clearly lying — proper Halloween tension without graphic content. Workplace-safe.
- No game master needed. The host plays as a detective alongside everyone else. Nobody sits out.
