Super Mario Bros./World 4

Part 1

 * Get on top of a high "?" block, and wait for the wily Lakitu. You'll make him drop to the ground if you jump on top of him--an effective ambush.
 * In Vs. Super Mario Bros., there is a bottomless pit after the four coins and you have to jump over small wall.

Part 2

 * Collect all of the coins in the "?" block platform. Then quickly get back to the top.  Stand on top of the third block, and jump to collect a hidden 1-up mushroom.
 * You can't reach the coins from the ground, so use the wall as a stepping stone. Then clean up!
 * The second pipe leads to coin room D.

Part 3

 * The mid-air block below the stairs is a 10-coin block, so first go down and collect all 10 coins. Then jump up on top of the same block, go back to the top of the stairs, and make your victory leap to the flagpole.
 * In Vs. Super Mario Bros., after you emerge from the coin room, between the 2 pitfalls is a flying Paratroopa. After that there are two walls you must jump over.
 * Also in Vs. Super Mario Bros, there is a gap in the staircase leading to the flag jump.

Part 1

 * Get the three coins and blast the block that's farthest to the right overhead to collect a power-up.
 * It's difficult to deal with Goombas when the ceiling is low. But if you are Super Mario, you can blast through the overhead blocks and gain valuable headroom.
 * There is a 10-coin block hidden inside the low ceiling. It's the 5th block from the right, second one up.  Cash in!
 * If you don't want to risk falling into the pit for a Mushroom from the ? block, you can punch the one to the right to bump the Mushroom in the other direction.
 * In this platform column, you will only see one platform at a time instead of two. Move carefully!
 * The area after the lift is full of hidden coin blocks and a secret beanstalk. Punch the blocks except for the hidden coin directly beneath the beanstalk.  If you reveal the highest coin too early, it will be difficult to make the beanstalk appear.  Climb the beanstalk to find a Warp Zone.
 * In Vs. Super Mario Bros., the lifts now become smaller.

Part 2

 * There is a 10-coin block hidden to the left of the first pipe, and a star to the right of the pipe. Beware of the Troopas and Buzzies lurking below.
 * The second pipe in this section leads to coin room E.
 * By pressing the "right" button while you jump to the right lift from the left lift, you can land on the lower block even if you hit the blocks above you. The center block of the second block set contains a power-up.  You can also use the lifts to go above the ceiling to the Warp Zone which leads to World 5.
 * In Vs. Super Mario Bros., the power-up is omitted.

Part 3

 * Sprite limits may affect the platform. If there are four enemies on the end of the screen in Part B and 2 Green Koopas are walking to the right of the screen, you will only see one platform at a time instead of two in the beginning of this part.
 * Find a power-up in the block that's farthest to the left under the row of coins.
 * In Vs. Super Mario Bros., that block with the power-up is empty and where that green koopa is walking its a red koopa.
 * In Vs. Super Mario Bros., the bricks are not there above the pipe to end of the level.
 * To reach the top of the pipe, use the stairs to the left. If you fall to the left of the pipe, the Buzzy will almost surely get you.  When you go to the right from the top of the pipe, be sure not to bump your head on the ceiling because you'll fall into the bottomless pit!  It's better to jump down to the right first, and jump across.  If you're Super Mario, you can also go to the Warp Zone by punching through the ceiling.

Part 1

 * You have double trouble on the third island: 2 nasty Troopas pacing back and forth. You have to carefully kick them out of your way and right off the 'shroom.  Of course, Fire Mario can blast them with fireballs.
 * Use the "accelerate-jump" combination to get to the high fourth island.
 * Paratroopas fly up and down. Since they don't chase you, you can easily avoid them.  If you're an advanced player, however, you can even stomp them as you jump.  Be careful not to lose your balance trying to get the power-up on the right.  You don't want to fall off.
 * If you try to get the coin beneath the first lift just by jumping, you will bump your head and fall. Hop on the lift, then get the coin.

Part 2

 * Study the movements of these balance lifts before you cross. The best strategy is to get on the left side, and wait until the right side becomes the same height.  Then jump.
 * Stay on the final lift until it reaches the top and use to accelerate, then leap to the flagpole.
 * In Vs. Super Mario Bros., by the balance lifts there are less mushroom platforms to fall on and the bottomless pit near the flag pole is longer so beware!

Part 1

 * There are two routes. The lower hall is a trap.  You'll be stuck there with no hope of escape.  Use the top route to find your way.

Part 2

 * In this second half of the castle, you must take the lowest route or you'll be trapped forever.

Part 3

 * Be careful not to get hit by Bowser's fire breath. You can rest for a while in the low spot to plan your next move.
 * There is no horizontal lift above Bowser in this castle. If you are not Fire Mario, you may either dash and jump right over him, or you may run underneath him. Also, look out for the fire rod and Podoboo that have been thrown into the mix.
 * In Vs. Super Mario Bros., just before you get to that low spot, there are three gaps, the gap furthest to the right there is a Podoboo.
