In this puzzle you are shown a random completed logic circuit where the input values are given. The idea of the puzzle is to trace through the logic circuit and put in the correct values where the questions marks are located.
Click on the question marks to cycle through the values that you think would be present in the circuit given (either 0 or 1).
Once you have entered every value in place of the question marks, click on the “Check” button to check your answer.
When you click on the “Check” button the values will be checked, if you get them correct the background of the value will change to Green. If you did not get the value correct the background will change to Red.
If you get some values wrong click on the “Close” button and have another go. Once you have changed the values you can go back and select the “Check” button again to check your answers.
