Did you know that unnamed portals connect to each other automatically? I discovered this by accident after 300 hours of gameplay!
I had forgotten to name a portal at my base in the meadows, and then I set up a new portal in the plains. Before I could name it, it was already connected to the unnamed portal at home. I was a little scared to go through it, wondering where it might take me lol.
But it turns out that unnamed portals always connect to each other, no matter where they are in the world. This can be a useful feature if you need to create a quick and easy way to get back home. For example, you could leave an unnamed portal at your base and then set up unnamed portals at other locations around the world. When you're ready to go home, simply go through the unnamed portal at your current location, and you'll be teleported back to your base.
