DC23 Tamper-Evident Contest

[trebog42]

Inside the box:
1. plastic deposit bag - contained physical tamper locks. I am told one puzzle was to move the locks to the upper row in such a way that their values combined with the operators on the top row would come out to a specific value.
2. 8.5 x 11 - Manila envelope sealed with tamper tape. Inside the envelope there were two sealed "security" envelopes( Think what you would use to mail a letter or check). One contained what I assume was a crypto puzzle, I wasn't able to solve it. The other envelope contained a piece of paper with a picture printed on it you had to change the face on. This envelope also had metallic flashing tape on the inside that trapped moisture as you tried to steam it open.
3. A "security" envelope with a note inside wrapped in carbon paper (just plain evil) easy to mess up and leave carbon marks.

Can you post what you saw in the box? What was the puzzle?

I have participated for the last three years now, I would say you all out did yourselves with an incredible contest. We loved the new challenges and twists (e.g. the red plunger lock, the plastic deposit bag, the sealed envelope with flashing tape on the inside to make steaming difficult, etc...) It really stretched our minds and forced a lot of creativity.

We were ticked at ourselves for not recognizing the puzzle inside the deposit bag, but consider it a lesson learned for next year, look at everything! and then look at it again.

Shrink sleeves might be an interesting challenge.

Thanks to everyone who participated! We hope to expand the contest next year to include more exotic seals, additional challenges, and more tamper goodness! Next year we'll also be offering a low-time commitment version for those who want to try to tamper specific seals to perfection without needing to do an entire box.

For those that participated this year, what did you think of the contest, what would you like to see next year, and how can we improve? Feel free to post here or PM me!
