Signal Jammer ( 2,000 Store gem )

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 a jammer that hides the world name from Broadcasts and the world selection screen. When broadcasting, the world will appear as JAMMED!


  • Players can still enter the world by typing in the world name.
  • Friends can still enter if the player's warp is on.
  • The Signal Jammer does not hide the world during friendcasts.
