About This Game


The tubes are still on. The watchman is dead—the knife is still out.

Notary Block is a co-op suspense accusation horror for four to eight players, set in a Hong Kong twin-tower public-housing estate rebuilt from a real block. Stay alive in the blackout, turn the estate itself into evidence, and walk out through the ground gate—only if you cross it yourself.

What you do

Residents: hide, search, find bodies, hold a short meeting, vote. A vote that names the killer sheathes the knife and opens the gate—it is not a team victory. The watchman's keys open the same gate. You only got out if you walked through it yourself.

Killer: limited strikes, hide bodies, plant items, cut the main power, camp the gate. The fewer people who leave, the better your night.

How a round ends

The first resident through an open gate—or a correct vote—starts a forty-five-second sting. Then a personal night report for everyone: got out, died, or didn't leave. The first escape does not end the table.

The estate is the weapon

Grab and throw use real physics. Hidden bodies, blackouts, gated corridors, eyewitnesses and lies—accusations come from what happened on the floor, not from a case board. This is not stand-on-the-map-until-vote.

Who it's for

Four to eight on voice. About fifteen to twenty-five minutes per round. Traditional Chinese and English on the page; Cantonese-first in tone.
