In the Minecraft Java 1.19 update, players can either play the game alone or with other players in a multiplayer world.

Simply search 'Minecraft 1.19 Skyblock world' and go to one of the top websites like Planet Minecraft or 9Minecraft. From there, you will be able to download different kinds of Skyblock worlds.

Java Edition users of Minecraft will need Java installed. After doing that, you’ll need to download the version of Minecraft Forge that matches your server version.
