Wire & Gate: Light the Lamp!

Turn truth tables into working circuits

Wire & Gate puts the expected output next to a partially built circuit. Each row lists the values of inputs A and B, later adding C, so the puzzle is to choose gates that make the circuit's output agree with every target row.

The first circuit introduces AND with a single empty box. Placing the shown gate instantly filled the circuit's output column, turned all four rows green, lit the lamp, awarded three stars, and unlocked the next lesson.

One new idea at a time

The ten circuits move through AND, OR, NOT, NOR, NAND, and XOR before asking the player to chain two gates and mix rules. The final pair covers majority voting and a half adder, connecting the small puzzles to the way computers add binary values.

Inputs can be flipped at any time to watch current travel through the wires. That visible response makes a wrong gate useful evidence rather than a silent failure, especially once multiple boxes feed the same lamp.

Designed for a short browser lesson

Large tap targets support phones as well as desktop browsers, progress stays in local browser storage, and the game asks for no account. Sound is optional and the complete ten-circuit set is available without advertising.

The creator identifies the project as a one-person educational build by an electronics student in France. The itch.io listing explicitly states that no generative AI was used.

Guide

Read: Compare the target output column with the current circuit for every input combination
Place: Tap an empty question-mark box and choose the gate that matches the required truth table
Test: Flip inputs A, B, and later C to watch current travel through the wires
Solve: A circuit is complete when every truth-table row turns green and the lamp lights
Progress: Work from single AND and OR gates toward chained rules, a majority vote, and a half adder

Creator's description

Circuit 1 displayed the four-row AND truth table beside two input switches and one empty gate box. Selecting that box placed the introduced AND gate, matched all four outputs, lit the lamp, awarded three stars, and unlocked circuit 2.
