Latchwork. Turn the dial.
Mind the valves.

Each level is a brass machine on a table with mechanisms built into it. Turn the wheels, drag the gears, pull the levers, and work out from what moves what the thing wants from you.

Latchwork in play: a brass machine on a marble table, a dial in the middle of its front panel, a column of four empty windows to its left and a shuttered mechanism to its right, loose gears on the table beside it, and brass lanterns and copper pipes around the room.

How it works

Looktapwork it

  1. Look round the machine

    Drag empty space to walk the camera round the table. Each machine has several stations on it, and some of them are shut behind a shutter or a glass dome until another one is solved.

  2. Move in close

    Tap a mechanism to move in and work it. Pinch or scroll out to step back and look at the whole thing again.

  3. Work it

    Drag rings, wheels, gears and weights. Tap levers, mirrors and buttons. When a station is solved, the camera moves on to the next one that is open.

  4. Finish the machine

    Solve every station and the machine does what it was built for. That unlocks the next one.

How a level plays

One at a time

Stations that open in turn

On some machines the stations open one after another, and a station behind a shutter or a glass dome stays shut until another one is solved. What one station gives up is often what the last one needs.

All at once

Nothing finished alone

On other machines every station is open from the start and none of them can be finished alone. Each one wants something another station gives you: a tool, a key, water, steam or a card.

The details

Every machine

The satchel
On some machines, what one station gives you goes into a satchel at the top of the screen until another station needs it.
Hints
The hint button shows a plaque for the mechanism in front of you. The game counts how many you asked for, per level, and shows the count to nobody.
Every time different
The codes, the orders and the layouts are drawn fresh on every load, so the second time through is a different puzzle.
Made in code
Every texture and every sound is generated when the page loads. The game loads no image and no audio file.

Get it

In your browser

Latchwork is free and runs in a browser tab, on a desktop or a phone.

No account, no advertising, nothing to buy. The levels you have unlocked, the hint counts and the sound setting are kept in the browser you played in and go no further. It needs WebGL, and the start screen says so if your browser has none.
