1-Castle is the castle of World 1 in New Super Mario Bros. X. It is the first castle level in the game, filled with ropes and Podoboos. The boss of the level is Roy Koopa.


First off, Mario needs to climb a rope on the ceiling while avoiding the moving spiked platforms and walls, and also Podoboos and the lava. A ? Block containing a Super Leaf can be found next, followed by more Podoboos and rope climbing. Rising and sinking platforms, Dry Bones and more Podoboos will then appear, followed by the checkpoint. A multi-coin block which can be changed into a Gold Block can be found along with the ? Block containing the power-up. Mario will then have to rope-swing to the other platform. An area full of Thwomps comes after, and more rope-swinging, rising and sinking platforms, and Podoboos. Another Super Leaf can then be found. Mario will now have to rope-swing and avoid the Thwomps at the same time. A Super Thwomp will then appear (see Star Coin 3), followed by the boss door. A Super Leaf can be found in a hidden block to the right wall of the boss door.

Roy Koopa is the boss of this level. The walls of the room will slowly become narrow every time Roy is hit. Roy will charge at Mario at first, and will change directions if he misses. However, if Mario can bait Roy into hitting either wall, he will collide with it and become dizzy temporarily. Mario can take this chance to hit Roy by jumping on his head. He will then perform a shell attack, which Mario must avoid. After a moment, Roy will return and shoot a ball of magic, which Mario must also avoid. Roy will then charge again at a faster speed, and Mario must again bait him into ramming into a wall to stun him. Mario must jump on Roy's head three times before the key to the World 2 is released.

Star Coins

  • Star Coin 1: Mario must drop down from the rope onto a sinking and rising platform to collect the first Star Coin.
  • Star Coin 2: The second Star Coin is in the air with a group of Coins. Mario must hit some Invisible Blocks to find a hidden passage with a Super Leaf. He must run to gain power to fly in the air to collect the second Star Coin.
  • Star Coin 3: The last Star Coin is under a platform near a Super Thwomp. The Super Thwomp has to hit two rows of Cement Blocks for Mario to get the last Coin.
