When you enter the world of Honkai: Star Rail, you'll be overwhelmed by the many different things you can do. As you progress in the main story and level up, multiple Companion and Adventure missions will unlock on various planets. Some Adventure Missions can also last for up to three real-life days.

These missions are called time-gated since you can only progress to a certain point on a particular day. Night On The Mine is one such mission, and you'll have to solve three Mine Cart puzzles each day during this quest.

How To Unlock Night On The Great Mine

There are several steps before you can even get to this quest. Firstly, you'll have to finish the main story in Herta Space Station so that you can make your way to Jarilo-VI. In this area, you'll first have to go through the main story until you're taken to the underground city by one of the main characters.

Here, you'll eventually unlock the Great Mine area. Keep progressing the story until you see a certain exclamation point in Boulder Town. Once you see this symbol, you can start the quest by talking to Antonia and she'll tell you that there's an old mining person who's trying to teach his apprentice before retiring.

Go to this old miner in the Great Town area and talk to them for a bit to unlock the main puzzles.

How To Solve Mine Cart Puzzles

Each mine cart puzzle consists of some special mechanics that can be used to move the carts to their respective places:

  • When you push a cart, it'll follow the track laid in front of it. You can push the carts from either side, but their path is decided based on the shining yellow lines near the turnout devices. If you interact with the device, the yellow lines will be changed.
  • Each cart with ore in it needs to reach the path end that has a barrier with yellow light. On the other hand, the empty carts need to reach the blue end.
  • If there are more yellow path ends than the filled carts, you'll have to take an empty cart to the place where you can see ore on the ground. Fill up the ore here and take the cart to its location.

Once all the carts are in their positions, you can talk to the old miner to claim your prize. Talk to him again after claiming the chest to start the next puzzle.

The first few puzzles will be quite easy since the game lets you get used to the mechanics. For the very first puzzle, you simply have to interact with both the turnout devices once and then push the cart to the blue end. This will take the cart to its required position and solve the puzzle. You can get a normal treasure chest for it.

For the second puzzle, you first have to push the cart with ores into the track without interacting with any turnout devices. Once it stops in the middle of the track near the empty cart, interact with the turnout device labeled as one (left) once. Push the ore cart back and it will reach its location.

Next, interact with both the turnout devices once and push the empty cart so that it can reach the blue end.

To solve the final puzzle for the first day, push the empty mine cart into the track first without interacting with turnout devices. This will take the cart to the other end of the track. Now, interact with the second turnout device (right) once. Push the mine cart again and fill it with the ore on the ground.

Take the cart back and interact with the second turnout device again. Push the cart back to its original location and then interact with the first device (left) once. Finally, you'll be able to push the cart into the yellow track end.

  • Use the same turnout device again and push the ore-filled cart to the empty cart's original location.

The second puzzle of day two has the same layout as the first one, but the steps get a little trickier because of the colored end placements:

  • Change the direction of the third turnout device and push the empty cart. This will take it all the way to the other end of the track.
  • Use the third device again and push the ore cart to the empty cart's original position. Next, interact with the first and third devices to push the ore cart to another end near the empty cart.
  • Interact with the first device again and push the empty cart into its original position. After that, use the third device and you'll be able to place the empty cart on the blue end.
  • Finally, use the first and third devices again and you can push the ore cart to the yellow end.

  • Interact with turnout devices two and three once and push the empty cart right beside the ore cart. Switch the third device back and take the empty cart to the ore on the ground.
  • Fill up the cart and push it back beside the other ore cart. Interact with device three to change the track on the right and push the recently-filled cart back to its original position.
