It seems the sequences are in a relay race, with no clear end in sight.

  • Two eight digit sequences will flash with pauses between each sequence. One sequence will be completely white (referred as the secondary sequence), while the other will have each digit colored (referred as the primary sequence).
  • For each digit in order, perform the operation based on the color of given digit.
Red Add the current digit in the secondary sequence to the current digit in the primary sequence.
Blue Subtract the current digit in the secondary sequence from the current digit in the primary sequence.
Green Multiply current digit in the primary sequence by the current digit in the secondary sequence and take the last digit.
Yellow Divide the current digit in the primary by the current digit in the secondary sequence, rounding to the nearest integer if necessary. If you have to divide by zero, ignore this step.
White Cycle the secondary sequence right once.
Black Cycle the secondary sequence left once.
Orange Cycle the primary sequence’s digits right once.
Pink Cycle the primary sequence’s digits left once.
Purple Subtract the current primary digit from nine.
Cyan Swap the current digits and reverse the secondary sequence.
Brown Swap the current digits and reverse the primary sequence’s digits.
  • Take the absolute value of the sum of the digits from both sequences in order so that you obtain eight numbers.
  • For each number, refer to the table below and input the answer into the module.
-0 -1 -2 -3 -4 -5 -6 -7 -8 -9
