The Order of the Solutions

Like many others working on The Cipher Challenge, we did not solve the stages in the order they are presented in The Code Book. Below follows a list of the stages in the order we solved them.


Stage 1 September 23, 1999
Stage 2 September 24, 1999
Stage 4 September 26, 1999
Stage 3 October 4, 1999
Stage 7 October 10, 1999
Stage 6 October 12, 1999
Stage 8 October 13, 1999
Stage 9 November 12, 1999
Stage 5 May 15, 2000
Stage 10 October 5, 2000

Notable is that after solving Stage 9, it took us almost six months before we managed to break the elusive Stage 5. If one considers that we actually had all the information that Stage 5 could require when we had solved Stages 1-4, it actually took us more than seven months to conquer it.

A more detailed description of Stage 5 follows further down, but the lack of success with solving Stage 5 was very annoying for us.
