📢 Overview

Join us on this social media journey into programmable banking. Your mission: find all nine QR code pieces, assemble them, and unlock rewards. Let's crack the code!

Why Are We Doing This?

Dev culture encompasses more than just coding; it's about curiosity, craftsmanship, and community. At Investec, we explore systems and collaborate with other developers who share the same passion. So, let's keep doing that, and have some fun with it.

🏆 What's the Challenge?

This treasure hunt is for developers who enjoy puzzles, hex codes, and hidden secrets. The pieces will be hidden in LinkedIn posts, with two new pieces each week. Clues may be visual or buried in code - sometimes requiring a script to find them.

Think Advent of Code meets escape room.

🧠 How to Play

• Follow our LinkedIn page: New clues drop twice a week.

• Find the piece: Each clue leads to a unique URL.

• Collect all 9: Assemble the QR code from the pieces collected (💡 Use Figma/Gimp).

• Scan the QR: Follow instructions to call a secret API endpoint.

• The race: The first 10 humans to submit correct answers win bragging rights and rewards.

✨ What’s at the End?

Let’s just say… the API knows when you've arrived. 😉 (And yes, there are surprises, rewards and swag for the 10 fastest, cleverest solvers.)

[Example of winning swag] Special prizes and swag for the fastest final submission and nine follow-up prizes.
