Riddle For 18 Solvers Page 1: The puzzle has 18 different main methods, each for 1 page. Here they are ordered alphabetically and it also tells the answer length for each method. The rest of the pages are not in the same order. Page 2: nutrimatic: "canal" This is just a straightforward nutrimatic query. The puzzle part is just recognizing it as such. What makes this interesting is that it just consists purely of the Letter A. Page 3: hashing: "deaf" The task here is to do sha256 hashing algorithm on the word and look at the first four characters of the hash. There exists a very limited amount of real words that have such hashing property. Page 4: cryptography: "mulholland" The image shows some rabbits, so you're meant to google rabbit cipher and find some online tool to decrypt the ciphertext. The key is just straight up given. Different websites use different implementations, but at least this one works: https://www.browserling.com/tools/rabbit-decrypt Page 5: base64 "future" Here you're presented with a base64 looking string, but you're not meant to decrypt it in a normal way. The jester indicates that there's some slight trolling going on. Pay attention to the symbols + and = in the string, they act as mathematical symbols. The goal is to add the two sides of the equation together. There are multiple ways to do this, but the way I intended it originally was to convert each character to a numerical value based on the base64 index list. Then just add the values together to get a new number. With this new number split the digits into pairs and look at the index list again for new characters. Page 6: polybius "amino" This one's simple. The image depicts ascending, so all you need to do is to look at a polybius grid (with J missing ofc as that's always default) and move one space up from the letters of "frost". Page 7: cryptic "fast" You need to know a bit about cryptic crosswords to solve this one. Cryptics typically split the clue into two parts, the definition and the wordplay (indicator and fodder). Here the definition part is "quickly". "spot signs" acts as a hidden word indicator. "of a stroke" is the fodder. Looking at the words you can see that the words "fast" hides in the middle of it. As an added thematical bonus, "fast" is a famous acronym for remembering how to spot actual signs of a stroke (the medical condition). The genius displayed here is astounding. Page 8: morse "unit" As everyone knows, Marselo is a famous hint for morse code. Convert "game" into morse and then swap the symbols to get a new word. The swapping part is hinted by the darkness of marselo, he's usually white and jovial but here he's presented as straight up diabolical. Yeah so that somehow indicates inverting. The truth is that originally the page didn't even have Marselo. But the fans were dying to see some more Marselo action, so I had to put him in here. Page 9: transposition "echoes" So here I was kind of running out of ideas and just threw some stuff together without much thought. You're just meant to perform various transposition operations on the text. Columnar means to just read the text vertically. RF3 (de) means decrypted railfence cipher with a height of 3 (best to use cyberchef). Then reverse the text. Next do railfence encryption with a height of 4. Skip 2 originally was something else but it proved to be simply too obscure even for the most enigmatic riddleheads. Use the dcode skip cipher tool. Lastly reverse ofc. This gives legible text that is just the lyrics from the song "echoes" by pink floyd. Page 10: sempahore "blues" The arms indicate semaphore. Carefully look at how the two words are positioned in the image. Convert the words into semaphore (make sure to have the perspective be from the behind). Next up compare pairs of symbols from each side. For the left side word, take the left arm's position, and then do the same for the right side and then combine them into a new full symbol to get a new letter. Page 11: quipqiup "sanctuary" You don't actually need to use quipqiup here, you just need to think you do. Transcribe the mysterious symbols by using standard transcription notation of unknown symbols (standard a-z alphabet order). Doing this process eventually reveals that the final cluster of symbols give an actual word. If you use some random unique transcription alphabet for the sake of quirkiness, I don't know what to tell you. Page 12: atbash "slow" Just atbash the word. Page 13: a1z26 "mercy" The most keen-eyed solvers might be able to spot the word "sigma" if they read the text diagonally. This acts as a hint for the method here. Calculate the word value of each word (using a1z26). Then just do mod 26 on the numbers to get numbers that fit into a1z26. Page 14: error correction code "drop" The sphinxes hint at vertical reading of the binary. Also the yin yang symbols famously hint at infamous "the winner takes it all" method. Doing some research on wikipedia about error correction codes reveals that a common way to do it is by sending triplets of bits. This fits how the binary is depicted in 3 rows. For each column, look at which bit has the majority representation. Doing this process gives 28 bits, which is meant to be decoded with 7bit ascii. Page 15: binary "section" All the words here are the length of 8, strong indication for some binary shenanigans. The most well-read puzzle crackers might know that 8bit binary ascii for lowercase letters always starts with the pattern 011. Here every word starts with a vowel and 2 consonants. So the whole puzzle is just recognizing that a vowel represents 0 and a consonant represents 1. Page 16: remote viewing "solomon" The blank page tests your remote viewing skills. Using Davidm's remote viewing guidelines, you should be able to view an image of the ancient king Solomon. Page 17: tineye "exai" This page looks like some decryptable binary code, but actually all you gotta do is to reverse image search the binary grid to find that it's actually just an album cover of the Autechre album "Exai". Page 18: keyboard "inferno" The image depicts descending, so by using standard keyboard layout you should be able to get the answer easily by just moving down. Page 19: vigenere "threethreeonesixfiveonefourthreefourfourthreeonefoursixoneonefive" Decrypt the vigenere ciphertext 17 times with each of the previous answer words. If you missed one of the answers, you can just bruteforce the missing key with various vigenere bruting tools. Final solution: The vigenere plaintext gives numbers that are meant to act as indexes on the answer words. Using the page order gives you the phrase "name of the composer". Woah, which composer does it mean? Well the whole puzzle is actually inspired by the classical music piece "Music for 18 Musicians", which was composed by "Steve Reich", which is the final solution to the puzzle.
