Since my custom substitution cipher was the most popular attempt, I decided to make another one - its based on the same principle as the first one, but optimized with different characters so its easier to use & decipherable even with shorter texts. I also provided 2 texts this time, so you have bigger sample size.

Some info and hints:

- Text is in english, only substitution was used, no transposition

- Plaintexts are short snippets from 2 different books I like.

Hint #1 (Characters used in plaintext):

>!Plaintext uses 26 letters of the alphabet (doesnt differentiate between lowercase and uppercase) + two additional characters!<

Hint #2 (Characters used in cipher):

>!Every letter of the alphabet can be written by 2 different characters, with the exception of 8 characters that technically can be written by more. I had to make this exception for readability, not to mess with letter frequency. Another exception are the two extra characters that can be written only one way.!<

Hint #3:

>!The 2 extra characters are used to mark begining and end of a sentence.!<

Edit: added Hint #4: >!Which character is used is determined by the letter's position in the sentence.!<

If needed I am willing to provide more text, just ask in the comments. If you are able to decipher it (or even if you are not), I would love some feedback to know what I can improve.

If you have any additional questions or need more hints please ask in the comments.

If the cipher wont be solved in 48 hours, I will add more hints. Also if needed I am willing to provide more text, just ask in the comments. If you are able to decipher it (or even if you are not), I would love some feedback to know what I can improve.

Info:

- Text is in english

- Uses both substitution and transposition

Still learning how to make good and fun to solve ciphers, any feedback is appreciated! If solved, I would also loved to hear about the process used. If you need any more hints or have any questions, feel free to ask in the comments.

Glhf solving!

Important info (transcription at the end) :

- The plaintext is in English, might contain slight grammar errors since I'm not fully fluent (shouldn't contain spelling mistakes tho)

- Cipher does not distinguish between lowercase and uppercase, contains only a-z, no numbers, no spaces

- Only substitution was used, no transposition

If you have any additional questions or need more hints, please ask in the comments, I am willing to provide anything needed!

Important info:

\- The red periods, commas and question mark are not part of the cipher, they are just periods/commas/question mark. Spaces are also just spaces between words.

\- The text is in English, might contain slight grammar errors since I'm not fully fluent (shouldn't contain spelling mistakes tho)

\- Only substitution was used, no transposition.

\- The grid is not important for the cipher. It's there to help me write the characters. The numbers around should work as coordinates if you need to ask me about specific character/word.

\- Everything in one grid square is one character - even the numbers (for example "70" is considered one character)

\- Similarities between characters don't matter in a sense that they have different meaning (for example "70" means something else than "circled 70")

I mostly want to find out how hard it is for experienced people to crack the cipher. If you are able to decipher it (or even if you are not), I would love some feedback to know what I can improve.
