Step 2: Decrypt Displayed Digits

  • Split the encrypted numbers on the display into 5 number pairs in reading order.
  • Convert each number to a digit using the field from Step 1. Each number’s corresponding digit can be found in the cell at the number’s position, counting in reading order (top-left is cell 1).
  • Each pair will make a new two-digit number.
  • Modulo each two-digit number by 26 and convert them into letters using A1Z26. This will form a keyword.

Step 3: Inputting

  • Find the keyword’s corresponding pixel art in the table below.
  • Start with the top left cell in the pixel art. If that cell is , press the corresponding digit in the same position in field 1. If the cell is , do nothing.
  • Repeat this for all cells in the pixel art in reading order.
