This is a 4 bit adder with carry. It is implemented as a half adder and 3 full adders. Each row of buttons is a number with low bit towards the entrance. The output is a series of gates that will all open when your guessed numbers add up to the encoded number. Oh, and the bit order of the output is scrambled. :)

That's an interesting try 'n error puzzle with 7 possible codes I think, as it looks like a binary adder, by twice 4-bit. Great work then! ^_^
I'd love you to play and comment my " PortCalc ". And if you like it harder, you also may want to try my " Circle of Alive ".
