Riddle 6

First, you must figure out which letter to keep in each of the four letter strings.

does not count – keep the letter that is not a roman numeral

impose order – keep the letter that when removed makes the remaining three stand in alphabetical order

forex – keep the letter that when removed makes the remaining letters spell out the acronym for a common currency

was it a bat i saw – this is a palindrome; keep the letter that is symmetrical around its vertical center axis.

odd one out – keep the letter that has an odd index in the alphabet, A = 1 as usual

no note – keep the letter that is not a musical note

not in line – keep the letter that is not in the word “line”

without letting go – keep the letter that does not require lifting the pen from the paper when drawing it (I’m a bit unsure of the explanation to this one, this was the most reasonable one I could come up with)

no pressure – bar is a unit of pressure, remove the o

melt – keep the letter that remains when frozen water melts 😉

Now comes the second part. Click the image to see a set of mathematical expressions.

Riddle 6 expressions

Convert the letter you kept in the first row to a number (A=1 as usual). Here the expression is only a ?, so just assign that number to the bat variable.

Next, convert the letter you found in the second row to a number and substitute ? for it, then substitute the bat with what you found from the first row. Calculate the resulting expression and take what you get modulo 26. Assign the result to the chain variable.

I suggest using the searchbox on Google for the calculations, it can handle very large numbers. Type in e.g. (23 + 12^2 + 18^4 )^3 % 26 and you will see what I mean.

Next, convert the letter you kept in the third row to a number and substitute the ? in the third expression for it, substituting the chain and the bat from what you previously obtained. Evaluate the expression %26 and assign the result to the grim reaper variable.

Keep doing this until you know the value of all symbols. Convert those values to letters (A=1 etc) and the right column will spell out your answer from bottom to top.

Since the answer is not anagrammed, and since not all expressions contain all previous symbols, it is possible to solve this riddle without getting all the letters in the initial step right.

Riddle 5

Ah yes, the riddle from hell. It is not as bad as it seems though.

Click around a bit to understand what is happening. Clicking the gates changes their type. Clicking the pentagram simulates your created circuit using the input to the left. Your output is displayed with red x’s where it does not match the actual output to the far right. After a simulation of the circuit, the next click will generate a new random input sequence and a new random constellation of gates. Gate types remain the same.

For those completely unfamiliar with binary signals and logical gates, this riddle will require some googling. Learn what AND, OR, NAND, NOR-gates etc are. Some quick reading will get you up to speed.
By expirmentation you can determine the types of the gates. Check the input to a gate, set it to the first gate type and simulate to see what the output becomes. Do that for all inputs (0,0), (0,1) and (1,1), and you will have enough information to know what gate type it is (obviously you can’t choose the inputs, but just keep clicking that pentagram until you by chance get the desired input to a certain gate).
You will figure out that the gate types are:

Upper left – NAND
Top middle – XOR
Upper right – NOR
Bottom left – AND
Bottom middle – OR
Bottom right – NEXOR (sometines known as EXNOR)

When you know this, generate a new random input and gate constellation and set the gates so that the given input produces the given output (to the far right), then click the pentagram. This step is the larger part of the riddle. You only have one chance per circuit to get it right, since circuit resets upon simulation, so you gotta make sure that the gate types you have set will produce the correct output.

Good luck!

Riddle 4

The hint beneath the image tells you to first subtract each number from its sibling letter (convert the letters to numbers first, A = 1 etc). This will give you one word (when converting back to letters). Next, instead of subtract, add the number. This will give you another word.

Riddle 3

First find thekey.php as per the riddle title.

thekey.php

Hover your mouse over the blood footprints from left to right and you will see words appear. In each set of words, there are numbers spelled out.
There are seven numbers in total. Six sets of words, but one of them contains two numbers.

Start from the beginning of the sentence in thekey.php and walk steps according to the numbers you found, in the order they appear when hovering from left to right. Never go back to the start of the key, just keep going. Do not count spaces.

You also found an Old Letter. It is not important for this riddle, but the year written in the lower right corner may be good to keep in mind.

Riddle 2

The letters read spunom puilq, which is not much of a phrase. There is a stain in the middle looking somewhat familiar. Stare at it for a while and you may realize it is a world map turned upside down. This hints you to rotate the image 180 degrees. Now the letters should be readable.

Riddle 1

Note that the letter next to each example image in the top half is the second letter of the word each image describes: cRoss, fIre, bOok, bAt, oWl, sKull.

Just use the second letter of the symbols in the bottom row to get the answer. Hint: The third symbol is a greek letter, which has a name.

Riddle VIII

First go to primer.php and guidance.php as per the riddle title.

primer.php
guidance.php

In the center of the image in guidance.php is an “Unholy Bible”, and the image text reads “LaVey”. Googling reveals that the book in the middle refers to the Satanic Bible, which is comprised of four books:

The Book of Satan
The Book of Lucifer
The Book of Belial
The Book of Leviathan

If you look up Lucifer on Wikipedia you will find that it means Morning Star. Belial has been called the worthless, and DCLXVI is roman numerals for 666, which is loosely the number of Satan. Hence the last book, with the question mark, must be The Book of Leviathan.

Clicking The Book of Leviathan takes you to furtherguidance.php.

furtherguidance.php

Read about the Book of Leviathan to learn that it contains Enochian Keys, symbolized by the keys in the image. The meaning of the direction of the arrow has thus been established. Since there is another arrow pointing away from the keys, namely to the red pentagram, this must mean that whatever the red pentagram symbolizes, must also contain the Enochian Keys. Hovering the pentagram, gives the word “Magic”. A magic that happens to contain the Enochian Keys is Enochian Magic.

The pentagram has two arrows pointing toward it, which, based on our established meaning of arrows, means that Enochian Magic contains (or consists of) six books. Reading about Enochian Magic confirms that indeed it does, and that the sixth book, which is hilighted in the image, is called Liber Loagaeth.

Go to liberloagaeth.php (or liberlogaeth.php seems to work as well) to find a digital copy of this book. You will find it is full of “Leaves” which is basically a bunch of grids of symbols.

Go back to the main page, towerhalls.php, and you will quickly realize that 17A, 20B, etc refer to different grids in the book. You are given a bunch of coordinates in the different grids, [R,C] meaning that the first number indicates row and the second number indicates column.

From here it is pretty straight forward. Find all the symbols the coordinates describe and then use the primer.php to translate those symbols into letters. Note that RGLUCEDG has two G’s in it, the second letter and the last (8th) letter. Similarily, one of the strings of symbols has the same symbol in place 2 and 8 which suggests that string of symbols is simply RGLUCEDG written in symbolic.

Riddle VII

The text beneath the image says you have found a key that does not fit the lock of this particular door. Here you should remember the locked mill in riddle III. Go back there and you will now be able to click that door, leading you to a modified version of the diary entry from that riddle. You will also find a “Piece of Paper” which is needed to solve a future riddle.

Modified diary entry

In this version of the diary entry, there are black bars covering the ten plagues. Use some image editing tool to cut these bars out and overlay them in the main image of riddle VII. Put the bars with their left end at the vertical line, by the icon corresponding with the plauge the bar covered.

The icons from top to bottom are:

tears turning red
reptiles
biting
insects
farm animals
symptoms
pouring (a bit stretched I guess, but a lightning probably means a storm)
swarming
shadow
eldest son (the skull represents the death of them)

Be very exact when you are cutting out the bars from the diary entry image. You must get the bar, the whole bar, and nothing but the bar. Also it is important that you place the beginning of the bar EXACTLY at the vertical line. When you’ve done this, use the first visible letter at the end of each bar. Read them in the order the plagues appear in the diary entry.

Riddle VI

This is basically trial and error to try to fill in the blanks in the clue beneath the image.

  1. Any symbol is correct if it is above a black circle.
  2. Any symbol is correct if it is to the left of a white circle.
  3. Base-down triangle is always correct when present.
  4. Cross is correct if there is a square in the constellation.
  5. Diamond is correct if it is white.
  6. Base-up triangle is correct if there is a plus with opposite color in the constellation.

Riddle V

You are running on some field. Escaping from people with hay forks.

You must figure out what date it is this day, given almost no information. But the information available is enough, as long as you have access to Wikipedia.

Note that the sun is in the constellation Leo. Go to Wikipedia and check between which dates the sun is in Leo. You will find that it must be sometime between August 10 and September 15 (as the clue beneath the image states, the tropical and sidereal zodiacs are incorrect in terms of the position of the sun, IAU must be used).

Furthermore, it should be clear from the context of the riddle that this takes place during the dark ages sometime. It was also previously specified (in the story of riddle IV) that the previous tailed star (comet) was 158 years ago. Go to the “Great Comet” entry on Wikipedia and check the historic appearances of great comets. The only two comets that are 158 years apart are 1066 and 1264, thus we must now be in 1264. Clicking the comet in the picture gives the clue that it was at its brightest a week ago on the 20th, suggesting that today is the 27th. It must thus be August.
