Switchyard

Wires cross. A light blinks on. Somewhere in the dark, a gate flips and an output changes from 0 to 1. Switchyard puts logic circuits in your hands. Connect inputs A, B, and C through AND, OR, and XOR gates. Watch a truth table update instantly as you toggle each value. No timers. No penalties. Just cause and effect, wire by wire. Study the Field Manual for worked examples like First Light, All Together, and Odd Company. Each one breaks down its gate sequence and explains the logic in plain language. Then head to Challenges and test what you’ve learned. Twelve puzzles await, each asking you to rewire and reconfigure until your output matches the target pattern. Tap a gate to change its operation. Tap a wire to reroute it. Save a circuit when you find one worth keeping. Reset when you want a clean slate. A LIVE indicator confirms that every change ripples through the circuit in real…
