Circuit Breaker
Choose the logic gate · AND, OR or XOR · that turns the two inputs into the target output
About PlayMemorize Circuit Breaker
Circuit Breaker is a gentle introduction to boolean logic gates · the building blocks every computer chip is made from. You do not need any background: each round shows you two inputs, a target, and three gates to choose from, and the game spells out exactly what every gate does.
How a round works. You are given two inputs, A and B. Each one is either 0 (off) or 1 (on). A logic gate takes those two inputs and produces a single output, called OUT. Your job is to pick the gate · AND, OR or XOR · whose output matches the TARGET shown, then press Run circuit.
The three gates, in plain words. AND outputs 1 only when both inputs are 1. OR outputs 1 when at least one input is 1. XOR (exclusive-or) outputs 1 only when the two inputs are different from each other. Tap a gate and the game shows its current output live, so you can check your reasoning before you commit.
What it trains. Reading a rule, applying it to specific values, and confirming the result · the same precise, step-by-step thinking used in programming, electronics and mathematics. A correct answer grows your streak; one wrong answer ends the run.

FAQ
-
What is Circuit Breaker?
A short logic-gate puzzle. You see two inputs (A and B, each 0 or 1) and a target output. Choose the gate · AND, OR or XOR · that turns those inputs into the target, then run it. One wrong answer ends the streak. -
What do AND, OR and XOR mean?
AND gives 1 only when both inputs are 1. OR gives 1 when at least one input is 1. XOR gives 1 only when the two inputs are different. The game restates these in-screen every round, so there is nothing to memorise. -
What are A, B, TARGET and OUT?
A and B are the two inputs (each 0 or 1). TARGET is the output you are trying to reach. OUT is the output your currently selected gate produces · when OUT matches TARGET, you have the right gate. -
Do I need to know electronics or coding to play?
No. Everything you need is on screen: the inputs, the target, and a one-line description of what the selected gate does. It is designed to teach the idea of a logic gate from scratch. -
