"Get off the grid! Install a Signal Jammer! A single punch will cause it to whir to life, tireless hiding your world and its population from pesky snoopers - only those who know the world name will be able to enter. It's a perma-Item, it's never lost when destroyed."

The Signal Jammer is an unsplicable solid jammer foreground block.


When toggled on (via punching), a Signal Jammer will change its appearance and hide the name of the world it is placed in from broadcasts, private messages, and the world selection menu, causing it to appear as "JAMMED!" (in the case of the selection menu, preventing it from appearing entirely).


  • Having an enabled Signal Jammer in a world doesn't prevent others from entering the world by typing its name directly.
  • The Signal Jammer does not hide the world's name on the friend list.
    • It does not hide the name on friendcasts either.
