The results will be up on the website and emailed out shortly. Thanks very much for your patience, I know it has taken ages. The prizegiving will take place from 6pm on Monday 8 July upstairs at the Marquis Cornwallis pub in London WC1. I hope to see lots of you there.

You can feel free to discuss the hunt on social media now. What puzzles stumped you? What "aha!" moment are you most proud of?

Mr Wily has asked me to tell you that he will reward you if you can tell him the identity of the person(s) who double-crossed him, or any information that could help catch them. Include all this in your answer document

You should submit your answer document even if you haven't found the treasure. Most teams don't - there's still lots of points up for grabs.

Does anyone want an extra team member? I've got a guy from San Francisco who was tackling the hunt solo and would like to join a team. I'm sure he'd be an asset to any team. Drop me a line if you can adopt him.
