Current Draw

Wire the board. Keep it lit.

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

New in 4.0: a finish line on every bench, Endless for score chasers, and the Diner. Start free on 12V and keep the board lit. No ads, no tracking, no pay-to-win. Current Draw is a calm game of current and consequence. Power sources feed the components that crave them. Draw traces to wire each source to consumers of the same color, keep every part fed as the board grows week after week, and carry it all the way to the finish line — without ever letting two colors meet on one line. Simple to draw, ruthless to untangle. HOW IT PLAYS • Wire — drag to lay a trace from a source to a matching consumer. Every cell spends from your trace budget; switch to Erase and it all refunds. Rethinking is free. • Match — only matching colors trade power. The pro move is one shared bus per color, pooling its sources to feed the whole net. • Feed — LEDs sip; coils and motors gulp. A ring of pips shows each part's demand. Let the ring fill and the part overloads. • Insulate — two traces touching one part shorts it. Tying two colors into one network is a cross-fault. Either is fatal in twelve seconds. Drop a bridge to route power through a part, or to let two lines cross without connecting. • Grow — every week pays out trace, and on a slower beat the board opens up, a fresh source arrives and a spare bridge lands. Every third week, choose one of three upgrades. • Finish — each bench has a line to reach: 1,000,000 points at 12V, 1,500,000 at 48V, 2,000,000 at 400V. Every clean week builds Uptime, a ×1–×5 multiplier; one full ring or one fault resets it. A flawless run takes about 45 weeks — cross the line and the whole grid comes online. • Endless — or switch the title to Endless: no line at all, just the score, running until the grid fails. THREE BENCHES Start free on the 12V garage bench. One Full Unlock opens the 48V rig and the 400V grid — faster, denser and unforgiving, where the wire runs neutral copper and you trace every route yourself. FIVE BOARD FINISHES Soldermask is the classic green board, lit and glowing. The optional Finish Pack adds three more: the exposed copper of Bare Board, white linework on drafting blue in Blueprint, and Drafting Paper — parchment drawn in technical-pen ink, where a wire states its load by line weight instead of glow. The Diner, sold on its own, turns the whole game into a pink gingham diner: ovens for power, treats to feed, wire piped in frosting. Finishes are cosmetic. They never touch difficulty, scoring or leaderboards. BUILT NATIVE A hand-built, Apple-native game — designed for iPad, just as at home on iPhone, and ready for iPhone Duo. No engine bloat, no ads, no pay-to-win. • A board you can read — every part is drawn as real hardware: power modules, LEDs, displays, fans, motors and coils, each in cast glass over the substrate, wired with copper traces that warm toward gold as the load builds. • Instruments, not menus — the controls are a soldered module on the board, right down to the trace stubs dropping to their vias. • Built to be read — color-blind cues you can switch on (a shape badge per net, a line pattern per powered bus, and a CVD-safe palette), plus Dynamic Type and Reduce Motion throughout. VoiceOver labels the controls and speaks faults, week ticks and upgrades, though laying a trace stays a sighted interaction. • Best Runs — your own history, finishes first and fastest first, with where you stand as a percentile instead of a rank with no denominator. • Game Center — fastest-finish and Endless leaderboards on every voltage, the original score boards kept as Classic, and achievements to chase. • iCloud — your runs follow you across iPhone and iPad. • Up to 120 Hz on iPad Pro. FAIR BY DESIGN The 12V bench is yours free. One optional Full Unlock opens both harder tiers — a single purchase that never expires. The Finish Pack and the Diner are cosmetic and change nothing about how the game plays. No ads. No tracking. No pay-to-win. Draw the line. Keep the power flowing.

Every bench now has a finish line. • Reach it: 1,000,000 points at 12V, 1,500,000 at 48V, 2,000,000 at 400V. A flawless run takes about 45 weeks. • Uptime: every clean week raises a ×1–×5 multiplier on every delivery. One full ring or one fault drops it back to ×1. • Pace: a line under the stats shows how far behind a flawless run on your own board you are. • Grid Online: cross the line and power runs out through everything you built, then your result is stamped: Apprentice, Journeyman or Master. • Fastest-finish leaderboards on every voltage, and five new achievements, including Flawless and Megawatt. The original score boards stay up as Classic, every record intact. • Endless: switch the title to Endless and there is no line at all. The score runs on until the grid fails, a line under the stats races your best, and Endless has leaderboards of its own, with phone and iPad boards ranked apart. • The Diner, sold on its own: a finish that turns the whole game into a pink gingham diner. Pipe frosting from the ovens to the treats that ordered, and serve your way to the finish line. • Motion that follows the copper: wire grows as you draw it, power runs out to each part as a circuit closes, and menus power on like chips. • Sound to match: a note as the current reaches each voltage card, a chime as a circuit closes, a whoosh or a buzz as a new part lands, and an arpeggio as the grid comes online. • The title screen is wired up: each voltage card sits in its own circuit, with current running through it. • New parts are easy to spot: a new source sends a pulse out from where it lands, and on 12V and 48V a new consumer flashes a square around itself. • Best Runs ranks finishes first, fastest first. Your earlier runs are kept under Classic. • A paused board can no longer be wired by accident: drawing waits until you resume. • iPhone Duo: folded, it plays like any iPhone; open it, even mid-run, and the board fills the big screen and turns with the phone. • iPad mini and 11-inch iPad: the voltage cards and the controls along the top now fit the screen. • Fixed a crash that could happen when starting a run.
