## On the Subject of Colorful Madness

I hope you don’t have chromophobia!

Take the 1st, 3rd and 5th characters of the serial number.
These will be your main 3 characters.

• If any of your main 3 characters is a letter, convert it to a number:
• Where A = 0, B = 1, C = 2, D = ... etc.
• If there are any buttons with both red and yellow colors:
• Add the number of batteries to each of your main 3 digits.
• If there are any buttons with 4×4 checkerboards:
• Calculate the difference between the number of such buttons and the number of ports.
• If the number you got is negative, get rid of the negative sign.
• Subtract that number from each of your main 3 digits.
• If any of your 3 main digits is negative, get rid of the negative sign.
• If there are any square-on-square buttons:
• Multiply each of your main 3 digits by the number of battery holders plus the number of port plates.
• If any of your 3 main digits is greater or equal to 10:
• Subtract 10 from it until it’s smaller than 10.
• If the 1st main digit is equal to the 2nd or 3rd main digits:
• Add 1 to the 1st digit until it’s not equal to the 2nd nor 3rd digits.
• If the 1st main digit reaches 10, convert it to 0.
• If the 2nd main digit is equal to the 1st or 3rd main digits:
• Subtract 1 from the 2nd digit until it’s not equal to the 1st nor 3rd digits.
• If the 2nd main digit reaches -1, convert it to 9.
