Introducing The Golden Challenge

by Gili Yankovitch

Hi to all you backers and supporters!

Once again, thank you for helping make this project possible. We’re about to cross the 100-backer milestone, and I couldn’t be more grateful for the energy and enthusiasm this community has shown. Every step forward is thanks to you.

On the production side, I’ve started work on the packaging; I’ll share more details about that soon. Shiny stuff is headed your way! It’s already shaping up to be something really fun and I’m excited to show you what I’ve been working on.

In the last update, I shared the online emulator: a way to get your first taste of the Sword’s challenges and practice them virtually. That was just the beginning, though, and today I’m happy to reveal something brand new…

This week I’m introducing The Golden Challenge. Hidden on the Sword of Secrets website, this unique puzzle is now live and waiting for you to take it on. The twist? The first five challengers who solve it and prove their solution will receive a very special reward: a Golden Sword of Secrets finished with a shiny ENIG coating!

The challenge is available right now at: http://swordofsecrets.com/.

Thank you again for being part of this journey. Your support and excitement keep me pushing forward and I can’t wait to share even more with you in the coming weeks.

More soon,
Gili
