Throughout the North Pole Subterranean Labyrinth there are 6 hidden chests that will give you KringleCoins, Hints, and other goodies if you can figure out how to reach them.

Finding the Chests

The best way that I discovered to locate the chests is to simply zoom out your browser window as far as you can and wander the area.

Reaching the Chests

Reaching the chests is a matter of locating the hidden 'path' that will allow you to reach them. While this can be done by running yourself into walls until you find your way blindly in the dark, we can find a way to simplify things if we investigate the image elements that make up the site.

Each area of the map is made up of several image layers, including /images/backgrounds/*area*_foreground.png, and /images/background/*area*_mask.png image. The combination of these layers is what hides our avatar when we move into the darkened areas of the map. If we can prevent our browser from loading these images, then while it will distort what we see on the screen, it will allow us to see ourselves as we move through this hidden region, making it much easier to find the path.

To do this using Chrome based browsers you can setup a local override for these images (Developer Tools > Sources > Overrides), and there are extensions for Firefox that will do the same. But in my case I opted to use the ever useful Burp Suite.

In Burp Suite, simply add two lines to the 'Match and Replace' section of the Proxy Options that will replace mask.png and foreground.png with nothing. Note that this will result in invalid requests for the element /images/backgrounds/*area*_, but the page will still load fine.

Chest Rewards

Standing on the chests will give you various rewards. In my playthrough all the chests gave me KringleCoins. 2 of the 6 gave me hints for the Blockchain Divination objective, and while the other 4 indicated they were giving me hints for Exploit a Smart Contract, only 2 hints were received. And one gave me a special Tophat.
