You can connect to Blockgame just like any other Minecraft server. The Server Address field should be mc.blockgame.info as shown in the image below! You can connect in any client v1.18.2 to v1.19.4 in either Java or Bedrock edition without anything other than the URL. If you're on console you can get connected using this quick Setup Guide.
You don't need any special downloads, resource packs, or anything beyond the Vanilla client. All of this is built through server-side modifications so you don't need anything to get started!
