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.
