You're a Secret Agent! 🕵️

You send secret notes to your friend Fox.

But this guy wants to peek...

Snooper Bot! Let's make codes he can't crack.

Stage 1 of 3
The Magic Wheel 🎡

Your first code slides letters to new spots in the alphabet.

Spin the wheel until the secret word appears!

Spin to decode!

Great work!

But watch what Snooper Bot does...

Trying every spin really fast!

Stage 2 of 3
The Number Lock 🔐

This lock uses multiplication!

Pick the two numbers that multiply together to open it.

Find the factors!

Amazing!

Big numbers take a long time to crack...

(That's 89 × 97 — tricky!)

But meet... Quantum Bot!

Stage 3 of 3
Hidden Garden 🌷

This new code works like hide-and-seek!

You hide a treasure, then hide it among lots of fake treasures.

Only YOU have the key to find the real one.

Tap a square to hide your treasure!

Quantum Hero!

Amazing job, friend! 🎉

You've finished Quantum Quest 1 time(s)

You just learned Post-Quantum Cryptography!

Grown-ups are building these new codes right now to keep messages safe in the future. 🌍🔐
