On the Subject of Multicolored Digits

Could they just not decide on one color?

  • A number will appear on the display.
  • Each individual digit is colored. Using the table below, alter each digit based on its color on the display. If two or more adjacent digits have the same color, treat them as separate digits, not a single number.
  • Use Table 1 to determine how each color affects a digit.
  • Complete four stages to disarm the module.
  • The number in stage 1 will have 3 digits, with the amount of digits increasing by one with each completed stage, all the way up to stage 4, which contains a 6-digit number and an extra procedure, which will be explained on the next page.
  • After typing the new number, press “Submit”. Submitting a wrong answer will result in a strike.
  • Use the “Clear” button to erase the current input.

Table 1: Colors

Color Alternation
Red Leave the digit as it is.
Green Add one to the digit. (9 loops to 0)
Yellow Subtract one from the digit. (0 loops to 9)
Blue Multiply the digit by two. (use LSD*)
White Use the vertically-adjacent digit on the keypad.
Magenta Add two to the digit. (9 loops to 0)
Cyan Subtract two from the digit. (0 loops to 9)
Orange Multiply the digit by number of batteries. (Use LSD*)
Purple Subtract the digit from 9. (0=9, 1=8, etc.)
Grey Multiply the digit by sum of all visible digits. (Use LSD*)

*Least Significant Digit

  • During stage 4, one of the digits will be replaced with a question mark. The color of the question mark is irrelevant.
  • Use Table 2 to determine the digit and its color.
  • The row is determined by the least significant digit of the sum of all digits (except the question mark) before changes.
  • The column is determined by the least significant digit of the sum of all digits (except the question mark) after changes.
  • Simplify the expression in the box to determine what the digit is. The color of the digit corresponds to the row that box is in.
  • Use the least significant digit and/or absolute value of that total.
