How to Get 99 Lives in New Super Mario Bros DS

Using a Koopa Troopa on Level 2-4

Go to level 2-4.

Finish the level like you would do normally, except when you get near the flag at the end, there should be a Koopa Troopa coming down the stairs.

Jump on it as it is coming down the third to last stair. If this is done correctly, you can keep jumping on it to build the points.Get 99 Lives in New Super Mario Bros DS Step 4 Version 2.jpg

Finished. After you build the points as high as it can go, it will start to give you one-ups. You should be able to take your hands off the DS and watch your lives go up. You can get up to 99 lives. Keep in mind that you may lose lives through time out.Get 99 Lives in New Super Mario Bros DS Step 6 Version 2.jpg

Getting them Through World 4

Go to the level where you go underground, the one infested with the Bob-bombs.

Go to the place where the bombs come out of the pipes. Place the bomb where under the pipe.

It should explode.

Kill the Koopa right next to it and make it shell-dash.

Wait for a spiny to start dashing on its own after you did the trick with the Koopa.

Keep following it but do not touch it, or it will start the process again. It will keep killing bombs. Beware that you could lose lives by running out of time.Get 99 Lives in New Super Mario Bros DS Step 13 Version 2.jpg

Using the Mega Mushroom in Level 1-1

Go to level 1-1.

Hit the block with the Mega Mushroom inside.

Wait until it is about to fall down the pit. Collect it before then.

Rush to the flagpole and then knock it down.

This will get you five one-ups.

Keep playing the level over and over again.

Using the Red Koopa Troopa on Level 1-4

Jump on the red Koopa Troopa 1 time, hold the Koopa by holding the X or Y button.
