The 4166 1899 puzzle in Big Walk, often encountered near the game's red tower, requires players to locate a specific set of coordinates on the game's map. The puzzle involves a locked box containing a red gourd, with the numbers 4166 and 1899 displayed on a sign above it.

To solve this puzzle, players must understand that the numbers on the sign represent map coordinates. Accessing the game's map, typically unlocked after completing the red tower and utilizing its key, is recommended. This map displays latitude (Y-axis) and longitude (X-axis), allowing players to pinpoint the location (4166, 1899).

Before embarking on this journey, acquiring certain in-game tools can be beneficial. The map itself is essential for navigation. Walkie-talkies, found southeast of the red tower, are useful for communication with teammates, especially for relaying coordinate information or confirming the retrieval of the gourd. An optional GPS device, located southeast of the green tower near a ski lift station, can further aid in pinpointing locations. This device displays current latitude and longitude via a light blue box.

The destination for the 4166 1899 puzzle is a rock formation on a hill. This location is situated south of a separate puzzle that involves counting faces on monitors within a green ring. To find the button that opens the gourd's box, players should look towards the side of the mountain when facing away from the red gourd prize, and then ascend the hill. The button will be located on the side of a conjoined rock.

It is crucial to hold down the button to keep the box open. The duration the box remains accessible is directly tied to how long the button is pressed. Once the button is held, a teammate can retrieve the red gourd from the box. If walkie-talkies are in use, the player holding the button can inform their partners about the successful retrieval.

For players working with limited team members, such as only two people, the map becomes a primary tool. If playing solo, a walkie-talkie can be equipped to a backpack, allowing a waiting partner to continuously provide coordinate reminders and updates on gourd retrieval. The map is particularly important in smaller teams as players may only be able to effectively utilize one item at a time when operating independently.
