How to get stars and constellations in the Blue Prince

There are several ways to get stars in the game. Each visit to the Observatory adds +1 star, just like the day that ends the planetarium, it earns you +2 stars. Certain items even receive bonuses, such as Morning Star from the Armory.

However, if you really want to get a lot of stars in Blue Prince, you need to use experiments in the lab. This process involves Collect all microchips So you can put them in the dial. This allows you to download a packet containing the reasons/triggers and effects of new experiments. Naturally, you want to choose the effect that grants +1 star.

As for the cause/trigger, there are two viable options in many cases:

• “Dig garbage every time” – This is good if you have a shovel, and even better if you draft the root cellar as an exterior room.
• “Every time you unlock or bypass the security door” – It's great if you have a key card or have the metal door disabled through a utility closet. You can also change the security setting to “High” to increase the number of metal doors in the estate.

Finally, the third option is very surprising, it almost feels like a loophole. To do this, you need to get a nursery: Nurse Station Pass Upgrade disk. If you have 10 steps or fewer steps into the room, the nurse station returns the steps back to 20.

Next you need to use it in conjunction with the “lost 10 steps whenever the map is opened” cause/trigger. Basically, you just keep going to open the map and re-enter the nurse station to regain the steps. If you play correctly, you can accumulate ridiculous stars indefinitely.
