Pocket Circuitry

HERE’S
THE IDEA.

Choose AND, OR or XOR for each gate. The first two gates process the labelled input pairs; the third combines their outputs. Match all eight rows of the requested truth table at the same time, then Test circuit. AND needs both inputs, OR needs either, XOR needs exactly one.

Pause, restart and adjust effects inside the player. Automatic previews never save results. Your progress shows its save status while you play.
