This is one of the best places to find new Minecraft Better Together seeds whether you play on Xbox, Windows 10, Nintendo Switch, VR, or mobile version. The seeds i've found are divided into separate categories based on what you find at spawn. The date represents the day the seed was found so you know how current the seed is.
You can use the date to discover whether the seed was found on the most recent update. Sometimes updates mess with a seed and the coordinates, causing structures to disapear. If something is really important and you want to play an older seed I recommend loading the map in creative first and checking to be sure what you really want is still there. I won't update old seeds I just find new ones. Each of the seeds includes a gallery in most cases of things you'll find on the seed, however all of the pics in the gallery are included in the coordinates.
