Deception: Murder in Hong Kong

A table of ordinary objects becomes a deduction puzzle when one player secretly chooses two of them as the solution. The scientist knows the answer but can communicate only through printed clue choices. The culprit joins the discussion and tries to make another explanation sound better. This introductory game uses only the scientist, culprit and investigators.

4–10 peopleThree investigation rounds; about 20 minutesDeception: Murder in Hong Kong base game: role, clue and means cards, scene tiles, six markers and badge tokens.

The quick version

Deal four clue and four means cards per player, then roles. The scientist discards their objects. With other eyes closed, the culprit shows the scientist one of each from their own display. The scientist marks six scene tiles, then replaces one in each of two later rounds. Everyone gets one formal solution attempt. An exact pair catches the culprit; surviving the third presentation round wins for the culprit.

Prepare the visible evidence

Use 4–10 people, one Forensic Scientist role, one Murderer role and ordinary Investigator roles for everyone else. Leave Accomplice, Witness and Event tiles in the box. Screen the object cards before dealing and omit unwanted subjects. This remains a fictional murder mystery; do not turn its descriptions into acted violence.

Deal four Clue and four Means cards face up per player, readable from across the table, then secretly deal roles. The scientist reveals their role and removes their own eight object cards. Give every other player one badge. Everyone except the scientist closes their eyes; the culprit opens theirs, silently indicates one of their own Clue cards and one of their own Means cards, receives acknowledgment and closes their eyes. Everyone opens their eyes.

Read the scientist’s limited vocabulary

The scientist lays out Cause of Death, one selected Location of Crime tile and four random ordinary Scene tiles. Place one marker on one printed option of each tile, in any order. Once placed, it cannot move. The others may discuss from the first placement onward. The scientist cannot give extra verbal, gestural or facial hints.

After all six markers, allow a brief discussion, then go clockwise from the scientist’s left. Each non-scientist gives a presentation of about 30 seconds without interruptions except a formal solution attempt. In round two, the scientist draws a new Scene tile, replaces one ordinary tile and chooses its new marked option. Cause of Death and Location stay. Discuss and present again. Repeat once for round three.

At any point before the final presentation ends, a badge holder may announce a formal attempt and name exactly one Clue and one Means card belonging to the same other player. Both must be the selected solution. A correct pair immediately wins for scientist and investigators. Otherwise the scientist says only no and takes that badge. The player stays in discussion but cannot guess again.

If nobody finds the exact pair before the third presentation round finishes, the culprit wins, even if everybody suspects the right person. Reveal the solution and discuss which tile choices helped. One case completes the game.

Give every theory a hearing

The objects’ printed words matter more than decorative details in the pictures. Ask speakers to explain a connection to the marked clues rather than accusing someone for being nervous. Before the final circuit, remind everyone that unused badges expire when that circuit ends.
