Therefore, in the cryptogram, Y=h and H should equal t. So far, 160 of the 280 letters in the cipher have been tentatively identified. The solution (in the first six cipher groups) would look like ...

Here's your chance to crack ciphers similar to those Bletchley Park's codebreakers faced during World War II. Below, we present three ciphers of different levels of difficulty, from easiest to ...
