SHEAR LINE

A lockpicking simulator that doesn't roll dice.

Play it now at lockpick.fun

The Ironhold Spool Trainer, mid-false-set: two pins captured, a spool lying about the third, and the plug swung 18 degrees round to nothing.

Most games turn lockpicking into a puzzle: connect the pipes, stop the bar in the green zone, or wiggle a stick until a hidden dice roll decides you deserve it.

This one doesn't. Every lock here is a real mechanism, simulated. There's no secret success chance and no progress bar. A pin sets because you held the pick still inside a window a fraction of a millimetre wide, long enough for the plug's ledge to catch under the driver. When a spool shoves your pick back out, that's a wedge on a bevel — worked out, not faked.

Twenty-two locks across four tiers, and a pick that bends when the lock pushes back.


Playing

It runs in your browser. Nothing to install, no account, and no network traffic once the page has loaded.

Want it offline? Every build is attached to the latest release as a zip. Unpack it, open index.html, and it runs straight off your disk — there's nothing in it to fetch.

Controls

You pick with the keyboard. The mouse is only for menus.

key what it does
Q, held The tension wrench. Nothing works without it.
Left / Right Move the pick to the next chamber.
Space, held Push the pick up. Let go and the pin drops back down.
1 … 9, 0 Wrench pressure, ten steps from light to heavy.
Up / Down Trim the lift a hair. Training level only.
R Restart the lock.
Esc Pause.

Learn the wrench first. With no tension, nothing binds and nothing can be captured — you can lift every pin in the lock and achieve absolutely nothing. The game tells you so, in amber, until you've used it once.

On a phone: turn it sideways. Tap a pin to select it, drag up to lift, and the slider down the left edge is your wrench — off at the bottom, ten pressure steps above.

Where to start

Three short lessons sit at the top of the bench. Together they take about five minutes, and they're the whole game in miniature:

  1. Find the pin that's binding.
  2. Jam one on purpose, and learn what a reset costs.
  3. Meet a spool, and learn that a lock can lie to you.

There's no wall of text to click past — one line at a time, and it changes when you do something.

If it feels impossible

It might be the lock. It might also be the wrench.

Four levels live in Settings and you can switch between them at any time. Each one takes away exactly one thing:

level what you get
Training Everything, and where you start. The binding pin is bracketed, the capture window is marked, the overset zone is shaded red before you reach it, and the arrow keys trim your lift for you.
Easy The readouts, plus a progress dot on each pin.
Medium No pin dots. The meters and the pick's flex.
Hard No cutaway at all. The lock's face, your hands, and what you can hear.

The level buys time, not points. There's no currency in this game. Your only score is the rank on the clock, and the level scales the time you're measured against — 0.6x on Training, up to 2.5x on Hard. The same run is a C on Easy and an S on Hard, so picking blind pays off rather than just earning respect. Nothing is locked behind difficulty.

If you'd rather read the lock than listen to it, turn on audio subtitles in Settings.


Found a bug? Stuck on something?

Both are worth telling me about.

  • Bugs and ideasopen an issue. There's also a report an issue button inside the game, which fills in which screen and which lock you were on, so all you have to write is what went wrong.
  • Everything elsejoin the Discord. Questions, feedback, showing off a lock you built, or working out why that middle spool won't budge.
