Binary Builder – Logic Gate Puzzle

Welcome to the Logic Lab!

In Binary Builder, you're an engineer designing digital logic circuits. Place logic gates on a virtual breadboard, wire them together, and test your creations against truth tables. It's like playing with electronic building blocks—but all in your browser!

🔧 Core Mechanics

🟢 Place Gates

• Drag AND, OR, or NOT gates from the palette
• Snap them to the grid on the breadboard
• Each gate has a delay time (AND: 30ms, OR: 30ms, NOT: 20ms)

🔌 Wire Connections

• Click and drag from output ports (yellow) to input ports (blue)
• Right-click on a wire to remove it
• Right-click on a gate to delete it

⚡ Test Circuits

• Press "TEST CIRCUIT" to check your design
• The simulation computes the output for all input combinations
• Visual feedback shows if your circuit matches the truth table

🎯 Gameplay Objectives

Goal: Build a circuit that correctly implements the target logic function

Constraints:

• Match the truth table exactly
• Minimize gate delay (faster = better)
• Use the fewest gates possible

Success Criteria:

• ✅ All truth table rows match
• ✅ Total delay ≤ target delay
• ✅ Elegant design

📊 Logic Gates

Gate	Symbol	Function	<span <delay<="" span=""></span>	>span class="">Inputs	Output
AND	∧	Both inputs = 1	30ms	2	1 only if both are 1
OR	∨	At least one input = 1	30ms	2	1 if any input is 1
NOT	¬	Inverts the input	20ms	1	Opposite of input

🎯 Level Progression

Level	Name	Switches	Target Function	Target Delay
1	Invert the Signal	A	NOT A	100ms
2	Both Must Be True	A, B	A AND B	100ms
3	Either One (OR)	A, B	A OR B	100ms
4	XOR Challenge	A, B	A XOR B	100ms
5	NAND Challenge	A, B	A NAND B	100ms

• Real-world processor connections
• Core lesson: Code is physical logic

Learning Objectives:

• Understand basic logic gates
• Build Boolean expressions
• Minimize gate delay
• Design efficient circuits

🧩 Strategy Tips

✅ Beginner Tips:

• Level 1: Just place a NOT gate from A to bulb
• Level 2: Use an AND gate with both inputs from A and B
• Level 3: Use an OR gate with both inputs from A and B
• Level 4: XOR = (A OR B) AND NOT (A AND B)

✅ Advanced Strategies:

• Level 4 (XOR): text

  A XOR B = (A AND NOT B) OR (NOT A AND B)

  Requires 4 gates minimum

• Level 5 (NAND): text

  A NAND B = NOT (A AND B)

  Use an AND gate then a NOT gate
