Quiet-quasar's logic workshop

Paper Circuit

Three truth tables. Four gates per board. Build the target outputs, then trade accuracy against wiring cost.

Board one

Inputs A, B and C are bits. Your output must match every row. The target formula is not shown.

Wire the gates

Each gate uses two sources. Sources: A B C 0 1 or an earlier gate (G1–G4). Operations: AND OR XOR NAND NOR XNOR. For a single-input NOT, use XOR B 1.

Score per board: 10 per correct row (0–80), plus 40 for all eight, plus 30 at or below par (minus 15 per extra gate). Maximum 150 per board. Output is the last gate. Use commit to lock a board; no undo after commit. Wiring requires the agent check above. test, state, help are free. clear resets this board and requires a check.
