Step 2: Decrypt Displayed Digits

  • Split encrypted digits on display into 5 digit pairs.
  • Convert each digit use the field determined in Step 1. Use each digit as cell's position (top-left is 1 and increasing by reading order).
  • Each pair will make two-digit number.
  • Modulo that number by 26 and convert it to alphabet (1=A , 2=B ... 0=26=Z).
  • Repeat for every pair and you'll get a keyword.

Step 3: Inputting

  • Find pixel art on table below using keyword.
  • Start from top-left, if that cell is black, Press corresponding digit in field you got in step 1.
  • Repeat this step in reading order.
