Fictional business concept. Local demonstration only. JavaScript is off - this static page shows the same information without the playable cabinet.

Latch Lab

A little mystery. No long instructions.

Try nine playful shutters, then ask about a real group experience.

The cabinet

How the cabinet works: press one shutter and it flips along with its touching neighbours above, below, left and right. No diagonals, no wrapping across rows. All nine shutters dark means solved. There is no timer and no penalty for exploring.

One tiny puzzle

Nine buttons and three utility actions make the mechanic immediately testable. With JavaScript enabled, this page adds the playable cabinet, undo, an exact hint and reset.

A hint, not a penalty

No countdown, login, score shaming or forced sharing.

For a small group

Describe proposed venue formats without invented opening times or addresses.

Small-group play - ask about a format for a few friends or colleagues.
Puzzle-led experiences - an original fictional sample of the venue direction.
Private session enquiries - availability remains with the real owner.

Illustration of an anonymous tabletop puzzle setting with props, no people.

Before a visit

Ask the owner about access, age suitability and availability. This demonstration does not reserve a slot, take payment or collect player details.

A real enquiry, separately confirmed

No booking confirmation or collected player identity.
