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 | |
| 0- | 69 | 43 | 94 | 86 | 12 | 53 | 87 | 65 | 08 | 67 |
| 1- | 89 | 42 | 35 | 76 | 18 | 74 | 56 | 43 | 29 | 01 |
| 2- | 00 | 46 | 57 | 80 | 18 | 49 | 81 | 43 |
