Logic circuit aim

Help

In this puzzle you must draw out the correct logic circuit by adding the correct gates into the diagram and connecting the inputs, outputs and gates together using wires.

Click on the correct logic gate button at the top of the screen to add it to the diagram.

To join the inputs to the gate click and drag on the small circles until the line connects to another small circle on the gate or output as appropriate.

You can tell when the line has connected correctly as the line will change from a red colour to a blue colour.

If you make a mistake simply double click on the gate or wire to remove it.

Once you have everything in place and connected together click on the “Check” button to check your answer.
