Challenge 1: Finding the laboratory

Walking around the streets in the snowless South Lake Tahoe, you find a lost personal diary. As you turn to the first page, you realize it belongs to the famous and eccentric Professor Swen Hemerson. Something’s very suspicious with the diary title though… can it be connected to the lack of snow??? Nobody knows where his lab is, but you might have few clues to figure it out.

Write down the 3 digit combination



Cut, fold, glue and you’ll get the clue!

X=X and O=O

Six houses are on Terry Lane — go on and check again which one belongs to Professor Swen.

Follow his daily route through the city, and park his car next to the graffiti.

Parking spot + Car — the solution is not so far.

  1. Assemble the city map, using the four illustrations.
  2. Cut, fold, and glue these 3 illustrations to make a 3D object.
    step 2
  3. “Build” the tallest building and the donut shop in the proper position in the city.
  4. Locate the professor’s home on the map.
    His address (Terry Lane #132) is given in the lost diary. Terry Lane is the bottom street on the map. If you start counting the houses on Terry Lane from left to right, you will notice that all of them have even numbers (120, 122, 124, 126, 128, 130, 132), so his house is the one in the bottom-right corner.
    step 4
  5. Start driving the mad mobile from his home and follow the instructions.
    step 5
  6. When you park the mad mobile in the right parking space, the 3-digit address will be revealed (382). Half of the number is written on the mad mobile and the other half is on the parking place. Connecting these line patterns will give you the code!
    step 6

Challenge 2: Entering the snow attractor machine core (SAMC)

Entering the lab wasn’t a big problem, but another challenge is ahead of you! At first sight, everything looks ordinary about his lab, but there must be something else to the whole story… he must be hiding something bigger than this! 

One door got your attention… a strange noise is coming from behind it… and it’s ice-cold to the touch. 

You realize it’s locked with a 3-digit code! 

Better hurry up to find the right combination — the clues are all around you!

Write down the 3 digit combination




The steps are clear — follow them and the snowflake will appear.

Put the snowflake in the right place, and look through the empty space.

Pay attention on the test tube label and connect it with the periodic table.

Sum the atomic numbers of the chemicals in the test tubes.

  1. Create the large snowflake using the origami instructions!
    step 1
  2. Place the snowflake above his experiment sketches. A clue will appear through the snowflake holes. It says “SUM THE ATOMIC NUMBERS OF THE CHEMICALS IN THE TEST TUBES.”
    step 2
  3. The test tubes in the lab are filled with (Br, Cs, Kr, Hg). Find these chemicals in the periodic table and sum their atomic numbers (35+55+36+80=206). This result is the logical combination for entering the final challenge!
    step 3

Challenge 3: Shutting down the snow attractor machine core (SAMC)

You are finally inside the core and one step away from putting an end to this madness. The huge machine, created solely by the egotistic professor, attracts all the snow from the clouds and funnels it into the nuclear reactor. During this process, a huge amount of cold energy is emitted in the room. He managed to simulate the greatest inventors’ minds and aggregate their knowledge into one powerful control panel that is beyond today’s technology. You have to find his unique logical pattern in order to shut it down. Once the SAMC is shut down, the reactor will burn the installation and destroy it forever.

Now, it’s up to you — make it snow again and save the beauty of winter!

Write down the 4 digit combination




In each biography, 2 hints you get to help you decide where the battery should be set.

North South East West, one name should be guessed! Take a look at every direction and with the 4 letters, make the right connection.

The name is SWEN, now check the code again!

  1. Two hints are given in each inventor’s biography. The first hint helps you find his/her invention, and the second one helps you identify the inventor.
    For example, Rosalind Franklin was a scientist whose work was very important in discovering the structure of DNA. (Hint #1).
    P.S. Ball pearl necklaces were often part of her style! (Hint #2)
  2. Each battery is marked with one innovation symbol that belongs to one inventor only. Cut out all the batteries and glue them in the right place.
    step 2
  3. Around the globe are the 4 cardinal directions. Those 4 letters are also an anagram of the professor’s name, SWEN. Because of his egocentrism, he thinks that his name is above all of the world’s greatest inventors, and he set up the code to be the numbers next the letters of his name (S=7, W=5, E=6, N=1).
    step 3

The destruction code is 7561
