A guide to completing World 6-3 in Super Mario Bros 1 for the Nintendo Entertainment System.

Get All the Coins

If you want to get a hidden 1UP in World 7-1, be sure to get all the coins in this level without dying! If you don't, the 1UP won't be there!

Explore World 6-3

In this mostly monochrome world, go to the right and use the moving platform to reach the two coins in the air. Get on the tree on the right. To the right of that, there is a spring. Press the jump button when the spring is compressed, and try to land on the moving platform above and to the right. Stay on the platform to get the 7 coins there.

To the right, use the moving platforms to reach the ?-mark block, which contains a Mushroom or Flower. Go right and use the moving platforms to reach the next tree.

Make a running jump onto the pulley platform, and try to let the other platform go up pretty far before you jump through the coins and get on the right platform. You need to be able to jump onto the next pair of pulley platforms. As with the first pair of platforms, you want to let the other platform go pretty far up before you jump on it, so you can reach the tall tree with three coins on it.

As you go right, you will start to see Bullet Bills randomly shooting from right to left. Get the four coins over the trees, then keep going right to find another spring. Use it to reach the moving platform up above.

From the moving platform, get on the left side of the pulley, get the two coins between the pulley platforms, then jump onto one of the trees on the right.

The platforms on the right will descend rapidly when you land on them, so don't stay on too long. Jump from platform to platform to get the two coins and reach the tree on the right that has another two coins just before it.

This is the last tree, so make a running jump to the right to reach the goal pole and continue to World 6-4.
