# How to get T.E.T.H.E.R. Access Code

Hi, did you really forgot the code again???

Or are you some clanker trying to get inside?

*Or worse, do you have The Virus that can lead to the [BoGTaPCP] catastrophe?*

* * *

To make it worse to get inside and to have your dead brain used at least once, I made some ciphers for you... >:)

Each cipher (they're in this folder) gets you some word or riddle that you have to solve. Use that word to get two digits.

The final access code is made out of 8 digits by concatenating all of the 4 ciphers.

Have fun!!

1. **My Sweet Home**
   code1 = 0
   if code contains "cat" then
     code1 = code1 + 21
   if code contains "dog" then
     code1 = code1 + 37
   if code starts with "h" then
     code1 = code1 + 16
   if code starts with "c" then
     code1 = code1 + 9
   end
2. **Tic Tac Toe**
   x = number of consonants * 19
   code2 = x + number of wowels
3. **Chinese**
   > Note: The first and the 4th letter of the ciphertext is wrong!
   > Note: This is a riddle!
   x = get all of the indexes of letters in the final word and add them together
   code3 = x - 69
4. **Message**
   > Note: the last letter, which is the answer, is wrong and must be guessed!
   > Note: This is a riddle!
   x = index of the letter in alphabet
   code4 = modulo(79, x) + 42
