Extra Lives
When you stomp on a turtle, kick it to the right and follow it. If it hits eight other turtles then you'll win an extra life.
Extra Lives on World 3
At the end of the third world you will see two turtles coming down. Let the first turtle go then jump lightly on the second turtle so that it is standing still on the steps (this will take practice.) Jump on the turtle again, if you do this right it will keep bouncing into the other turtle and give you points. After a while it will give you free men. Get as many as you wish, but be careful not to get more than 100 men because if you do when you die the game is over.
Extra Points
When you touch the flag pole, take note of what the time left is. If you touch the flag pole when the time left has the last digit 1,3,6, then you will get 1, 3 or 6 fireworks. every firework will give you more points
Minus World
To get to the never ending water level go to world 1-2. At the part at the end where there's a pipe going to the next level. Break two blocks so there's one at the end touching the pipe. Now duck and jump backward toward the brick (don't break it!) If you did this right you should go through the wall and pipe into a warp zone. Jump down the 1st pipe you see and you will be in the Negative World (-1)
Moon Walk
On level 4-2 at he begining you have to jump two things. One is big, the other is narrow. On the narrow one jump and hold down. (If you did this right you should be under some bricks.) Let go of down and keep holding left. Mario then will moon walk. Save Your Place
Try holding start when you die, just after it's too late to pause. You should begin the level where you died.
Warp to World 2, 3 or 4
On World 1-2 toward the end of the board start running and jump on the moving platform. Keep running and jump on the next platform. Again keep running and jump up on the top level of blocks (Caution! Do not fall off!) Keep running and you will see three pipes with snapping plants coming out of them fall down through the open area the plants will turn into numbers 2, 3, or 4 those stand for levels jump down a pipe and go to that level!
Warp to World 5
Make your way to the end of World 1-2 at the place where there's a pipe going to the next level. Break two blocks so there's one at the end touching the pipe. Now duck and jump backward toward the brick (don't break it!) If you did this right you should go through the wall and pipe into a warp zone. Ignore the first pipe, then jump down the second pipe and you warp to World 5-1.
Warp to World 6, 7 or 8
When you get to world 4-2, go past the first set of ? blocks and the elevator. Jump the hole and you will see a small staircase made of bricks. Break the brick underneath the top-left brick, then hit the top-left brick and a beanstalk will appear. Climb it to reach a special area where you can warp to worlds 6, 7 or 8.
