When circuit board by Jaze came on CTC, I loved the puzzle and the circuit board lines. Immediately I knew I wanted to do a puzzle with these lines myself. I didn't know how just yet. That is until I stumbled upon this lovely grid and placed the first line.

I knew that was it. The lines changed several times, but the very first endpoints stayed throughout. Slowly it took form, until it sort became this puzzle. There were just too many wires and it looked even messier than it does now. Then my friend Maximus mentioned x-clues and it clicked. That was the final detail needed to finish. Creating this puzzle and exploring what these lines can do has been a lovely and inspiring journey. I hope it's just as much fun to solve. Enjoy.

• normal Sudoku: Put the digits 1-9 once in each row, column and region.
• Digits separated by an X sum to 10.
• A digit at the endpoint of agoldenor asilvercircuit board wire indicates exactly how many unique digits are on that wire (including the two endpoints).
• When an endpoint is on multiple wires, it acts as an endpoint for each attached wire. Endpoints always have the same color as the wire they're the endpoint of.

This means R1C6 is both and endpoint for the wire from R4C1 to R1C6 and for the one from R1C6 to R6C9.
Equivalently there is a wire from R5C2 to R3C7 and one from R3C7 to R7C4 and R3C7 is an endpoint on each of these wires.
