3-Ghost is the Ghost House of World 3 in New Super Mario Bros. X.


As every other ghost house, the place is inhabited by Boos. A unique feature of the level is that the rooms and objects slowly swing back and forth constantly. Many P-Switches are found in this level.

Star Coins

  • Star Coin 1: In the very first room, a P-Switch must be activated in order to enter the wall and grab the Star Coin.
  • Star Coin 2: In the third room, the player must enter the lower-left door. In the next room, the player should activate the P-Switch, then run to the end of the room to use the Brick Blocks to reach the second Star Coin before the bricks turn back into Coins.
  • Star Coin 3: In the fifth room, the player must once again hit the P-Switch to turn the row of coins into Brick Blocks. If the player jumps fast enough, the player will discover a door hidden in the ceiling. The room there autoscrolls. The player must then use the P-Switch to work their way through the room. If there is still some time left in the P-Switch, the player must immediately Wall Kick their way up to the third Star Coin before the bricks revert back to coins.

Secret Exit

The secret exit is in the same room the third Star Coin is located, just through the door in the far-right of the room, This exit unlocks World 4-B.
