Reply To: The official Challenge 10 tips and hints thread
@Mattyrat, maybe you will be first this year.
@all, I noticed a few things this year. There have been more that the usual number of transposition ciphers,
and the latter ones were divided into blocks and used columns. Maybe Harry and the elves are suggesting that
10A and/or 10B use columns and blocks?
p.s. The best blocks are legos.
