Find the two spinable blocks, and jump very close to the same location to reveal one to five hidden blocks. Flame the two blocks and go in the tube. Get past the enemies to reach a doorway with a star on top of the gate. Complete the secret level to go to the Boss level.

Hint: Castle zone: Save a life:
When you are in the Castle zone and lose a life, turn off the game just before Mario starts going down. This is helpful when you have very few lives remaining.

Clear the Hippopotamus zone and the Space zone. Then, return to the Hippopotamus zone. Go to the left to get in the bubble. Once inside, go back to the left were you started. Go up to find a ? box that contains a heart. Collect the heart, then press Start to pause game play. Then, press Select to exit the level. Repeat this to collect up to 99 lives.

As soon as you enter the level, get Fire Power. If you enter as Super Mario, it will be easier. Go down to the very bottom of the water and go left. You will reach a small hole. Go down the hole (Fire Power is needed) and shoot the block to a small gap that only regular Mario will fit in. Once you break the block, get hurt and enter as regular Mario. You will find three blocks. Two of them will have hearts (extra lives) inside.

Go to the stage to the right from the bridge to the Hippo Zone. Find the secret star and hit as many enemies as possible. If you hit more than four enemies, you should get another life. This can be repeated as needed.

Go to the hippo, jump in the bubble, then go all the way to the top left. There will be a box with a heart (extra life) located there.

Hint: Hippopotamus zone: Money:
Go further into the level where there is a cloud that resembles a club on a deck of playing cards. If you cannot find it, there is a cloud that looks like an arrow that points to it. Fly up into the right side of that cloud and a money bag (50 coins) will appear.

Hint: Hippopotamus zone: Extra points:
Get in a bubble in Hippopotamus zone and travel close to the top of the screen. Towards the middle of this level you should see an arrow made out of clouds that is pointing up. Get under this arrow and go straight up from the bottom. You should hit an invisible box which will contain 100 points.

Hint: Macro zone: Secret level:
When you enter the first level of Macro Zone, you will go underground and have to navigate a group of floating ground-blocks. When you reach the second or third ground-block (it has five or six coin-blocks), jump up over each of the coin-blocks and a hard unbreakable stone will appear above each one, for four blocks. Jump on the stones. You will see a pipe sticking out of the ground, blocked by two fire-weak blocks. Shoot one fireball at each of them by jumping half-a-block's space to the left or right (whichever block you are shooting) then shooting them in mid-air. Jump up through the pipe. You will only have to shoot one ant. Go to the door that has a Star over it (shape of star). The level will close, dots will appear on the Macro Zone main screen, and will lead to a secret level. This secret level is a moving one but is not too challenging if you jump correctly. Note: You must have the "Flower-Power" for Super Mario. If not, find a "?" block and claim it.

Hint: Pumpkin zone: Secret levels:
There are two secret levels in the Pumpkin Zone; in the middle two games (the two before the Boss level). In the second game, you will find a secret level in the second big puddle near the end. There you will find a small opening in the bottom. At one point you have to break two boxes which block a tunnel going downwards. You do this by jumping and pressing Down while in the air. The second is in the level immediately before the Boss. It is at the end. Instead of going down the steps beside the ghosts, jump and fly across.

Hint: Defeating the Octopus Boss:
When fighting the Octopus Boss, duck and he will not be able to hit you.

Hint: Save a life:
When Mario loses a life and jumps in the air, pause game play and press Select. You should be outside the level with the same amount of lives. Note: This has no effect in the Castle zone.

Hint: Lose a life without losing coins:
The game will automatically save. To keep your coins after you losing a life, immediately turn off the game when you lose your last life. You should have all the coins you had before, and still have all the levels you previously completed.

Glitch: Fall through ground:
Go to a map where the is a long pipe. When in the middle going down the pipe, press Start then Select to get out. Go to any level. You will fall through the ground and be in another dimension. Note: This will not harm your game.
