Congratulations to everyone who tackled Challenge 5. We had 2601 submissions for 5B of which 898 were complete and correct, so extra special congrats to all those teams. Remember though that each challenge is worth more points than its predecessor, so even if you come a little unstuck with one round you can make up ground later on.
Challenge 6 will be published at 3pm this afternoon, and we have something a little different planned for 6A. It will be interesting to see which of you have the patience to complete it! If you are not already an expert you will definitely need to read Jodies Tip on the Challenge 6A page when it is published.
For those of you who are already accomplished, you might enjoy trying to break 6A without looking at the Tip. All credit to you, but I should warn you that 6A contains important information about 6B, so you still might want to tackle 6A quickly, in which case the Tip is extremely helpful. [Those of you taking part purely for the fun of it might want to ignore the hints in any case. It will be much more of a challenge that way, but will almost surely slow you down, Jodie]
We are really looking forward to seeing what you can do.
Good luck,
