You can play Minecraft Survival Multiplayer. Review the game server’s Changelog to see recent changes.  To play Minecraft, open the game, choose multiplayer, click “Add Server” and type memorymatrix.cloud in the Server Address field. Memory Matrix SMP is a Java-version Minecraft with regularly occurring allowances.   Randomly enchanted books are given out every couple of hours.  Other allowances may occur by request.  For some folks, emeralds are issued, for others name tags, an some even receive XP every 36 minutes.

There are no guarantees regarding the server and you play at your own risk.  The server’s status is available from Minecraft Server Status by Anders G. Jørgensen, MCS, & Minehost, among others.

This post serves as the changelog for the server and will receive future updates posted to it.
