Drag from a socket hole to another socket hole · click a cable to remove it
Cable trayChoose a cable, then wire the board.
This build deliberately does not use a board photograph as the play surface. The board is redrawn as clean vector artwork, but its geography, 30 infrastructure positions and individual socket-hole locations are traced from a perspective-corrected high-resolution photograph of the physical ElectraCITY board and cross-checked against the supplied board photograph.
Scenario 1: all three stations available; at least 20 infrastructure; no Super Cable. Scenario 2: one power station and Factory 5 unavailable; at least 20; no Super Cable. The sheet does not identify which station in Scenario 2, so the simulator asks you instead of guessing. Scenario 3: the middle station is unavailable; at least 20; no Super Cable.
These are unlocked practice predictions, not official 2026 conditions. They are deliberately labelled “predicted” in the scenario rail. They extend the same challenge ideas with station outages, the Super Cable, resistance restrictions and a final optimisation round so you can practise freely while keeping Scenarios 1–3 separate as the verified rules.
Short black $1, long black $3, short red $3, long red $5, Super $10. Black cable is higher resistance than red, the Super Cable has no cable resistance, long red is limited to six and Super to one. Power can be redirected through infrastructure and drops as the network expands.
The internal resistor values, actual current thresholds and exact electronic response of the physical board are not publicly published. Those parts are represented comparatively rather than being labelled with invented electrical values.
