## On the Subject of Digital Grid

Cruel Digital Root?

This module contains a 5×5 grid of colored numbers labeled 0 - 9, a button that says “check” and a button that says “reset”.

Press the “check” button to submit your answer. Submitting an incorrect answer will reset the grid and cause a strike.

Press the “reset” button to reset all numbers pressed.

The numbers can be colored red, green, blue, cyan, yellow, magenta and white.

Use the following rules to determine the correct numbers to press.

If the number you get exceeds 9 at any time while following these steps, take the digital root of the number and continue through the steps.

Step 1: Take the digital root of all the numbers on the module.

Step 2: Add all the digits of the serial number to this number.

Step 3: Add the digital root of all the red numbers on the module to this number.

Step 4: Add the number of port plates to this number.

Step 5: Add the digital root of all the yellow and green numbers on the module to this number.

Step 6: Add the number of batteries multiplied by battery holders to this number.

Step 7: Add the amount of white numbers on the module to this number.

Use the following table to find the correct letter to use. Use the number you got from the previous steps in the column, and the first rule that applies in the rows.
