Super Mario Bros./World 7

Part 1

 * The far left block above the twin cannons contains a power-up. Get on top of the twin cannons and punch from below.  Be careful not to get hit by Bullet Bill right after the power boost.  It's best to land to the right with the "down" button pressed.
 * In Vs. Super Mario Bros., there is a pit between the 2nd and 3rd Bullet Bill cannon.
 * It's quite tricky to deal with the Paratroopas with the "?" blocks above you. Play it safe.  Ignore them, and keep on going above the "?" blocks.
 * When you stomp and kick a Paratroopa, it will bounce back and forth between the cannons. Keep this in mind before you attack.

Part 2

 * There is a 10-coin block inside the second block from the right in the overhead block set.
 * When the Hammer Brothers move up, run under them quickly.
 * In Vs. Super Mario Bros., the bricks are "?" blocks. Next to the "?" blocks, the 1-up mushroom is omitted.
 * Before using the second pipe to enter coin room A, jump up to release the 1-up mushroom. Then go down and to the right to catch it, and return to enter the coin room.
 * ''In Vs. Super Mario Bros., there is a pitful before the remerging pipe from coin room A.

Part 3

 * The highest block contains a power-up, but the springboard is difficult to use, so don't try it when Bullet Bill is in your way.
 * Especially in Vs. Super Mario Bros. where there is a bottomless pit surrounding the springboard.
 * To avoid the Buzzy descending the right staircase, wait on top of the left staircase, and jump to the right when it reaches the bottom.
 * In Vs. Super Mario Bros., the Buzzy is replaced by Goombas which fall into a pit of water.

Part 1

 * This underwater scene is just like World 2-2. You can use fireballs underwater, so try to get all the enemies as they appear.  If they get away, they might sneak up behind you without warning.

Part 2

 * Proceed and collect coins with caution.

Part 3

 * If you go on top of the L shaped blocks above the drain, you'll see that Mario trembles from the force of the rushing water as if he fears his enemies. Try it out when you have plenty of time.

Part 1

 * Use the Troopas to blow away the Cheep-Cheeps.

Part 2

 * First, get the power-up inside of the "?" on top of the right bridge. Step back a little, and accelerate to jump over to the island.  Collect all of the floating coins during your jump.  Avoid the Troopas and Cheep-Cheeps at all costs.
 * The Paratroopas towards the end of this section never touch the ground. If you are regular Mario, you can run right by them.  If you are Super Mario, just kneel down to dodge them.

Part 3

 * Precise control and rhythm are necessary to clear these three bridge sections. Try to collect all the coins in the process.  Don't get bumped by a Cheep-Cheep from the bottom!  If this happens, your landing position changes.

Part 1

 * These lifts drop with your weight! Watch for the Podoboos and jump across quickly.  Proper rhythm and timing will save you from falling into the Bog of Flames.
 * Just remember one thing: Lava pools are only part of the background do not actually hurt you, but they are still located exclusively in pits. Therefore, ignore the lava and just worry about the pit.
 * The rest of this area is the same as the trap area in World 4-4. To clear it, you must follow a certain path.  One mistake is all you need to get trapped!
 * The correct sequence for this section of the map is to take the bottom path, followed by the middle path, and finally the top path.
 * For Vs. Super Mario Bros., the correct sequence in this section is to go from the bottom path followed directly to the top path.

Part 2

 * If you see a fire-bar suspended by some blocks, you've made it to trap zone 2.
 * To make it through this tricky zone, you must pass above the fire-bar, then walk along through the middle of the long block sets, and then finally back through the top pathway.
 * For Vs. Super Mario Bros., you must pass below the fire-bar, walk on the top pathways, and then take the final lower path.

Part 3

 * If you reach this low spot, you have cleared the trap zone!
 * In Vs. Super Mario Bros., the low spots are lava pits.
 * When the evil Bowser throws his hammers, get inside the arc of the flight path to avoid them. When he jumps, run underneath him to clear the stage.
