Tool Puzzle: Master Mechanic

Game Overview

Tool Puzzle: Master Mechanic is an innovative, highly tactile, physics-based narrative puzzle game that fuses spatial reasoning, mechanical logic, structural engineering, and satisfying workshop simulations. Set within the sprawling, retro-futuristic workshop of Mechanic’s Rest—a haven for eccentric inventors, automation repair specialists, and tinkerers—the game invites players into a world where every screw, gear, wire, wrench, and hydraulic piston carries real-world weight, friction, and functional logic.

You play as Arthur Pendelton, a former master machinist turned quiet repair shop owner living in the rust-tinted city of Gearford. When a series of mysterious regional power grid blackouts and automated infrastructure failures begin paralyzing the city, local citizens, industrial overlords, and mysterious whistleblowers start dropping off increasingly complex, broken, and enigmatic mechanical devices at your doorstep. From antique clockwork music boxes, steam-driven automations, and vintage automobiles to high-voltage power relays, heavy factory machinery, and top-secret military ciphers, every broken object brought into your shop tells a story and presents a unique spatial and logical challenge.

Unlike traditional puzzle games that rely on abstract tiles or simple color-matching, Tool Puzzle: Master Mechanic treats every tool in your workshop as a realistic instrument. You do not simply click a button to "fix" an engine; you must diagnose the underlying structural or mechanical failure, select the exact wrench size, calibrate torque wrenches to prevent stripping bolt threads, route wiring with appropriate voltage tolerances, cut custom gaskets, grease rusted joints, alignment-test gears, and carefully construct custom mechanical rigs to solve multi-stage physical dilemmas.

Storyline & World Building

The Rust of Gearford

Gearford is a city built on the shoulders of the Industrial Revolution, but elevated by steam-driven micro-computers, pneumatic transport networks, and intricate clockwork automatons. For decades, the city ran smoothly under the management of the Grand Engine, a massive subterranean mechanical computer housed within the city’s central spire. However, time, corruption, and neglected maintenance have caused the Grand Engine’s primary components to degrade, leading to widespread mechanical chaos across the metropolis.

The Repairman's Burden

Arthur Pendelton wants nothing more than a quiet life fixing pocket watches and vintage coffee grinders. However, when his estranged sister—an engineer working deep inside the Grand Engine—disappears, she leaves behind a series of locked blueprint boxes and custom-built mechanical locks that only Arthur’s specialized workshop tools can open. As clients bring in broken everyday gadgets, Arthur realizes that these devices contain subtle sabotage marks, missing key gears, and hidden micro-transmitters. By repairing these objects and assembling complex contraptions on his workbench, Arthur uncovers a corporate conspiracy aimed at destroying Gearford’s public mechanical grid to force citizens into buying expensive, proprietary corporate energy cores.

Core Features & Mechanics

1. True Physics & Material Simulation

Every bolt, screw, pipe, wire, and gear features realistic physics properties. Bolts can strip if over-torqued, pipes can burst under excessive fluid pressure, gears can jam if misaligned, and fragile copper wires will melt if overloaded with high current. Players must respect the physical limits of steel, brass, rubber, glass, and wood.

2. Extensive Interactive Workshop & Tool Wall

Your workshop features a fully customizable tool pegboard containing over 80 distinct, hyper-detailed mechanical tools:

Fasteners & Drivers: Slotted, Phillips, Allen, Torx, and Square screwdrivers; adjustable wrenches, socket sets, torque wrenches, and rivet guns.
Cutting & Shaping Tools: Hacksaws, wire strippers, pipe cutters, bench grinders, file sets, and precision chisels.
Electrical & Diagnostic Gear: Multimeters, oscilloscopes, continuity testers, soldering irons, and wire crimpers.
Measurement & Precision Tools: Vernier calipers, spirit levels, dial indicators, micrometers, and plumb bobs.
Heavy Workshop Equipment: Drill presses, hydraulic shop presses, lathe machines, sandblasting cabinets, and ultrasonic cleaning baths.

3. Open-Ended Diagnostic & Repair Gameplay

There is rarely only one way to solve a mechanical puzzle in Tool Puzzle. If a machine has a broken cast-iron gear, you can choose to weld the broken teeth back together, turn a raw brass blank into a replacement gear using the workbench lathe, or re-engineer the gear train ratio using smaller secondary gears scavenged from old junk drawers.

4. Custom Blueprints & Invention Sandbox

In addition to repairing client devices, players can access the Invention Bench. Here, you use collected spare parts, structural struts, motors, switches, and pulleys to build custom mechanical contraptions from scratch to solve external physical challenges—such as building a pulley-driven winch system to lift heavy debris or constructing a water-powered generator during shop power outages.

How To Play: Step-by-Step Instructions

1. Basic Movement & Camera Manipulation

Workbench View: The main game interface takes place at your primary workbench. Move the Mouse (or Right Analog Stick) to pan your view around the workbench and the tool pegboard behind it.
Zoom / Focus: Left-Click on a specific component of a broken device to zoom in for close-up work. Double-click or press Right-Click (or B / Circle) to pull back to the full workbench view.
3D Object Rotation: Hold the Middle Mouse Button (or Left Trigger) while hovering over a dismounted machine or part to rotate it 360 degrees in 3D space, examining it from all angles to locate hidden screws, cracks, or serial numbers.

2. Diagnosing Mechanical Failures

When a new item is placed on your workbench, do not immediately start dismantling it:

Step A: Visual Inspection: Rotate the object and check for obvious physical damage—such as stripped gears, burned wires, rusted joints, or missing screws.
Step B: Functional Test: Pull levers, turn hand cranks, or flip power switches to observe where the mechanical movement binds, squeals, or fails.
Step C: Diagnostic Tools: Use specialized tools from your pegboard. Touch multimeter probes to electrical terminals to test voltage drops, or apply a dial indicator to test shaft wobble.

3. Selecting and Handling Workshop Tools

Grabbing Tools: Click on any tool on your pegboard wall or tool chest to pick it up. The tool will attach to your cursor in a ready-to-use stance.
Matching Tool Sizes: Hover the tool over the fastener or component. A color-coded ring indicator will inform you if the tool fits:
- Green: Perfect match (e.g., 10mm socket on a 10mm bolt head).
- Yellow: Improper fit (risks stripping the bolt or damaging the tool if used).
- Red: Wrong size or incorrect tool type entirely.
Action Execution:
- Screwdrivers & Wrenches: Click and hold the Left Mouse Button, then move your mouse in a smooth circular motion (clockwise to tighten, counter-clockwise to loosen).
- Pliers & Wire Cutters: Click and drag across wires to strip insulation, cut lengths, or bend terminal leads.
- Torque Wrenches: Click and hold until the digital or click-scale gauge reaches the exact specified foot-pounds of force indicated in the machine manual.

4. Cleaning, Repairing, and Fabricating Parts

Not all broken parts can be replaced with new ones from inventory. You will frequently need to recondition existing components:

Rust & Corrosion: Pick up the wire brush or place rusty parts into the Sandblasting Cabinet. Move your mouse over the corroded areas until the raw silver or bronze metal shines through, then apply a layer of anti-rust lubricant.
Soldering Wires: Select the soldering iron, apply flux to the joint, hold the iron tip to the wire connection to heat it up, then feed solder wire until a smooth, shiny silver bead forms across the junction.
Machining Custom Parts: Move to the Bench Lathe or Drill Press. Secure your raw stock material in the vise jaws, set the spindle RPM according to the metal type (aluminum, brass, steel), and carefully feed the cutting blade using the handwheels to match blueprint measurements down to the millimeter.

5. Assembly and Testing Protocols

Reverse Assembly: When reassembling a machine, parts must often be reinstalled in the exact reverse order of disassembly. The game's Assembly Assistant (toggleable in options) can highlight the proper sequence if you get stuck.
Gasket & Seal Application: Always apply thread sealant tape to threaded pipe fittings or cut replacement paper gaskets using tracing paper and shears before bolting fluid or steam housings back together to prevent leaks.
Final Calibration: Once reassembled, plug the device into the shop power supply or fill its fuel tank, then perform a final calibration test. Verify that all gauges, dials, and indicator lights read within normal operating parameters before signing off on the repair job card.

Pro-Tips for Aspiring Mechanics

Keep Your Pegboard Organized: Return your tools to their proper pegboard slots after completing a job. A cluttered workbench makes it easy to lose small precision screws, washers, and micro-springs.
Organize Small Parts in Trays: When taking apart complex gearboxes, place removed screws and small pins directly into the Magnetic Parts Tray on your desk to prevent them from rolling off the table and getting lost.
Don't Force Stuck Fasteners: If a bolt refuses to turn and emits a harsh grinding noise, do not force it—you will snap the bolt head off! Apply penetrating oil, wait a few seconds, or apply gentle heat with a propane torch to expand the metal before trying again.
Consult the Master Shop Manual: Located at the corner of your workbench is Arthur's personal shop binder. It contains wire gauge conversion charts, gear tooth ratio formulas, thread pitch tables, and torque specifications for almost every device in the game.
Check Electrical Grounding: When repairing high-voltage equipment, always ensure the ground wire is securely connected to the metal chassis before applying power to avoid blowing shop fuses or damaging delicate micro-circuits.
