On the Subject of Word Encryption

After all, is this device electronic or mechanical? What are the gears doing?

• Identify the encrypted form of the given word.
• The encryption is done by replacing each letter with the letter that is a certain offset away in the alphabet.
• Use the keyboard to input the correct encrypted letter based on the current offset.
• Press the “↲” submit button when the encrypted word is typed.
• Submiting an incorrect word will generate a new word to decrypt and reset the offset to its initial value.

Offset

Each time a letter is pressed, the offset value is changed by the variation value. Meaning that the first encrypted letter offset is the initial offset value, the second encrypted letter offset is the initial offset value plus the variation value, and so on.

The offset value is accumulative, therefore, deleting a letter will not retrocede the offset.

To reset the offset to its initial value, use the “←” backspace button until all gears on the right rotate together.

• Refer to Initial Offset for the initial offset value.
• Refer to Variation for the variation value.

Initial Offset

The initial offset value is determined by the following Venn diagram:

Line	Description
	Bomb has one of the following ports: Stereo RCA PS/2
	Bomb has a type D battery.
	Bomb has a type AA battery.
	Serial number contains a vowel.

Variation

The variation value is determined by the indicators present on the bomb.

• In case of multiple indicators, the variation value is the sum of the variation values of all indicators present on the bomb. Do not sum indicators from the same group.
• For example, if the bomb has SND, CLR, and NSA indicators, the variation value is +3.
• Use the following table to determine the variation value:

Indicator	Variation	Group
SND	+1	A
CLR
CAR
IND	-1	B
FRQ
SIG
NSA	+2	C
MSA
TRN
BOB	-2	D
FRK
None	+1	-
