Mini
Circuits

A drag-to-wire circuit builder for iPhone and iPad. Wire glowing power to the parts that crave it, and keep a living board alight as it grows — one clean trace at a time.

Coming soon to the App Store

12V 48V 400V
Objective

A calm game of current and consequence.

Power sources feed the components that crave them. Wire each source to consumers of the same colour, keep every part fed as the board grows week after week — and never let two colours touch. Simple to draw, ruthless to untangle.

The loop

How it plays

01 · WIRE

Draw traces

Drag to lay a trace. Each segment costs 1 from your budget; switch to erase and it all refunds. Rethinking is free.

02 · MATCH

One bus per colour

Only matching colours trade power. The pro move: a single shared bus per colour, so its sources pool to feed the whole net.

03 · FEED

Mind the demand

LEDs sip; coils gulp 5×. A ring of pips is a part's pending demand — let it fill and ignore it, and the part overloads.

04 · INSULATE

Shorts & bridges

Two colours on one line shorts — red, and fatal in 12s. Drop a bridge to route through a part, or to let two lines cross clean.

05 · GROW

Weeks & upgrades

Every week the board grows and hands you trace. Every 3 weeks, pick 1 of 3 upgrades. Survive as long as your wiring holds.

Not a video

The bench, playable right here.

The real engine, running in your browser. Drag on the board to wire it. Pick a voltage and see how long you last.

minicircuits — web-v1.0

Same simulation as the App Store build — lane-aware routing, demand, faults, weekly upgrades.

Build notes

Hand-built, number by number.

A one-person studio game, built the studio way: exact numbers over adjectives, one doc per concern, everything regenerable from a script. No engine, no ads, no analytics.

Pure Canvas, no engine

HTML5 Canvas and vanilla JS. No build step, no dependencies, no framework — traces, signals and heat bloom drawn as geometry.

A deterministic core

The whole sim is pure logic over integer cell keys and a seeded RNG. Unit-tested, and ported 1:1 to a Swift package for the iOS build.

Accessible by law

Nothing rides on colour alone: shape glyphs, trace dash patterns, a CVD-safe palette, plus VoiceOver, Dynamic Type and Reduce Motion.

iCloud & Game Center

Best runs and settings follow you across iPhone and iPad. Leaderboards and achievements handled by Apple — we never see your identity.

Bus voltage

Pick your pressure.

Higher voltage spawns hungrier parts and ramps faster — shorter, sharper runs. Tuned against target session lengths in a headless economy sim.

12V
Hobby bench · guided

Traces light up the moment a circuit completes, so you learn the flow. The training tier — free to start.

LED · display · fan~15+ min
48V
Workshop rig · brisk

Fans, displays and motors with real appetite. Copper runs golden under load. Stay on top of it.

+ motors~10–15 min
400V
Industrial bus · brutal

Hungry motors and red-hot heating coils. Constant pressure, no mercy. For when the bench feels tame.

+ coils~5–10 min
Game Center

Score chased, weeks survived.

Leaderboards for score and weeks survived on every voltage, and six achievements to chase — from your first delivery to a kilowatt run.
