■ = Signal 1
■ = Signal 0
AND: both inputs = 1
OR: one input = 1
NOT: flips signal
Power flows through! You solved it.
The output didn't receive power. Check your gates.
Drag gates from the left panel onto the glowing empty slots on the circuit board.
Each gate processes the incoming signals.
AND — outputs 1 only if BOTH inputs are 1
OR — outputs 1 if at least ONE input is 1
NOT — flips the signal (1→0, 0→1)
Click a placed gate to remove it. Press TEST CIRCUIT to see if power reaches the output.
You've mastered Boolean logic gates! Every circuit is complete.
