  • There are 3 valves on the module. This is the module combination. To solve the module, submit the final combination.
  • Start by adding up the digits in the serial number.
  • If this sum is 0, the final combination is ⚫⚪⚫.
  • Otherwise, find the current combination in that position in the list on the left.
  • Examine the 1st character of the serial number.
    • If it is a number, move that many places backwards through the list.
    • If it is a letter, take its alphabetic position (A = 1, B = 2, etc.) modulo 10 and move that many places down the list.
    • Wrap around to the beginning or end of the table when needed.
  • If none of the valves in the combination you land on match the same valve in the current combination, move a space in the same direction.
  • If exactly 1 of the valves matches the same valve in the current combination, invert that valve.
  • Otherwise, if exactly 2 of the valves matches the same valve in the current combination, invert the remaining valve.
  • Otherwise, if the valves match the current combination exactly, this is the target combination. Do not move on to other serial number characters.
  • Repeat these steps with the rest of the serial number characters, using the new combination as the new current combination.
  • After processing all serial number characters, the current combination is now the target combination.
  • After finding the target combination, use the module combination and follow the rules below.
  • If the material of the valves on the module is silver, then toggle the entire target combination.
  • Finally, if a valve is black in the module combination, then toggle that valve in the target combination to get the final combination.
  • To enter the solution, press down every valve in the final combination that is black. 3 seconds after any valve is pressed, the module will submit its state.
