Minecraft wiki entry for Demo_mode, associated text: It is possible to play in-game modes other than Survival in the demo mode by opening up the world to LAN with cheats enabled and executing /gamemode command. This does not remove the time limit, or the demo message.‌[Java Edition only]
By going on the game files and deleting the files "level.dat" and "level.dat_old" will cause the timer to reset.
Additionally, a new bonus chest would spawn on the spawn point.
The demo mode can be played by all players regardless of whether they have yet purchased the game.
It is possible to install modifications on the Java Edition demo.
Servers can be started with the --demo flag (this is technically what the launcher does). Everyone who joins the server sees the demo message.
If one tries to play a demo version before 1.3 from the launcher using a non-premium account, they can play the full version.
This is because 1.3 is the version that added the demo mode to Minecraft, so earlier versions do not have the code necessary to recognize that they are in the demo.
Typing in "North Carolina" in the seed screen of the full version gives the same world seed as the demo version.‌[Java Edition only]
The “Forest Glade” in the seed picker of the full version gives the same world seed as in Minecraft Trial.‌[until BE Edition 1.18.0]‌[Bedrock Edition only]
If the Minecraft shortcut and directory is moved to another hard drive, etc., it remains in the demo version, and the previous worlds do not appear.
It is possible to enter the server list by opening to LAN and enabling cheats, then executing the /kick @s command to see the option to go back to the server list. However, servers cannot be joined due to an invalid session. This is because, in demo mode, usernames are not authenticated.
If a world is downloaded, it can be played by putting the world folder in "saves" and renaming it to "Demo_World". If there is already "Demo_World", it must be first renamed or deleted.
There is a chance that the demo timer has decreased or expired. This is due to the timer being used by the world's creator while building the world.
