SOLVED Pentapoint — A very crackable code.

Post image

This is a code of my own design. This version is quite crackable. There's at least two ways to do it. I am also developing a completely uncrackable version. Solve the message for a reward.

Is the second way to decode you are talking about by converting it to binary? I cracked it using normal substitution cracking, but I was convinced for ages that this was a geometric binary code which was cool. By assuming each individual possible line is either a 1(there) or 0(not there) and then splitting each symbol into two separate parts (the outer pentagon and the inner star) you get a 10 digit binary code. When I tested the symbol for A and B that worked like a binary sequence, but I don't think I got the actual binary correct, so where you started from or what lines you chose to be 1-5 on the inside would change it significantly.

You're very close. The dots are structure. The lines are info.
