It's a dark and stormy night, and the wind is howling outside your window. You're fast asleep, but the animal part of your brain hears your phone buzzing. A text message. It prods you awake. A text message, at this hour? Who could it be?

Then another text message. And another. Your phone won't stop buzzing. Who could it possibly be, this early? You turn over your phone and look to see who it is.

It's everyone! All of your contacts are texting you - family members, co-workers, long lost friends, even the number for the restaurant down the street - and all the text messages say the same thing:


That's funny. Something weird is going on with the phone. The phone continues to buzz from incoming messages, and buzzes long enough that you're fully awake. Then it stops buzzing. Suddenly there's an incoming video call from an unknown number. A picture of a white rabbit pops up.

Carefully covering the camera with your finger, you pick up the call. "Hello?"

The call screen materializes into a cartoon white rabbit. "Hello? Hello! Is it really you? Please, you're our only hope!"

"Huh? Who are you?" you ask.

"Ah, yes, allow me to introduce myself! I am the White Rabbit. I work for the Mad Hatter, perhaps you know him? We were referred to you by The Doctor." The White Rabbit waited for a reaction at a mention of the Mad Hatter, but got none. Suddenly it looked at its watch. "Oh! Oh my! Did I wake you! I just realized it's very late there! I mean, very early!"


"Well then, let me get right down to business. The Doctor said that you might be able to help us. We need someone to save the Wonderland economy!"

"Wonderland - you mean, like Alice in Wonderland?"

"Precisely! And we need someone who knows code! What happened is this: Bill the Lizard was dabbling in machine learning in his garage, and he built an artificial intelligence brain, which he named POOKIE, that became sentient and took over Bill the Lizard's house, and then all the banks, and then the library and the electrical grid and - well, everything, really. Now POOKIE is printing invisible money and disrupting the Wonderland economy!"

You scratch your head. "Invisible money?"

"Everyone was panicking about all the inflation caused by all the invisible money - pretty soon people had to cart around wheelbarrows full of invisible money just to buy a loaf of bread. Now POOKIE has sent us a crypto-puzzle, and said that if we don't solve it, it will keep printing invisible money. And Bill the Lizard is in pretty hot water, everyone in Wonderland wants his tail."

The White Rabbit stopped for breath.

"So, what do you think? Can you help us solve POOKIE's puzzles?"

You consider the rabbit. "What's in it for me?"

The White Rabbit jumped up excitedly. "Yes yes, of course, the reward, there is a substantial sum of extra credit points available, each puzzle unlocking points. The Doctor and the Mad Hatter have come to an agreement that will allow you to receive extra credit in return for helping us to defeat POOKIE and save the Wonderland economy! If you agree, we can get started right away, and send you the first puzzle we received."

"Well, alright, I guess I'll help you. But can I get some sleep first?"

"Oh, goodie! Yes, thank you, thank you, thank you! May I call you agent? I've always wanted to be involved in a spy caper. I'll call you agent. I need to think of a code name. How about 'White Rabbit'? Is it too obvious?"

Your eyes begin to droop. Sleepy.

"Well, very good, get some rest, and we will send along the first puzzle! When you're ready, get in touch by taking the Puzzle 1 Quiz on Canvas..."

The rabbit's image faded out.

Wonderland? White rabbits? Did all of that really just happen? You look at your text messages - no trace of any text messages about following the White Rabbit. You shrug. At least you'll get some extra credit out of it.

Now, back to sleep...


The White Rabbit says: POOKIE promised that this code would contain a secret word that would stop it from printing invisible money. Once you have found the secret word, take Puzzle Quiz 1, which will ask you for the word. Once you have passed Quiz 1, the Mad Hatter will deposit the extra credit into your account.

Good luck, agent.
