Challenge Seven - solution

How did you get on? A small variant on the ADFGVX cipher slowed you right down, but 96 correct entries was pretty good. I won't say too much about the solution, 'cause I figure you're pretty focused on the final challenge. The fifty pounds cash prize winners this week are:

James Lloyd from Portsmouth Grammar School
Jan Gondzio from James Gillespie's High School
Morty's Marvels (that's Thomas Woolley, Jamie Stone, Shani Martin, Sean Renshaw) from Mortimer Wilson School
Timothy Gale from The Leventhorpe School
Booth Dilkes (Jim and Silas Dilkes) from Rodborough School.

Congratulations to all of you and good luck with Challenge 8.
