[+] Hint: Turtle Tipping for 99 Lives

Hint: Turtle Tipping for 99 Lives

You can use the decades old turtle-on-the-stairs trick from Super Mario Bros. to get 99 lives in New SMB Wii. Go to world 2-3 and, at the end, right before the flag, you'll find a set of steps and a turtle ambling down them. If you time your jump just right you'll continue bouncing on the shell collecting lives until you max out at 99. For a video of this, check out the World 2-3 section New Super Mario Bros. Wii Guide. (Ed.'s note: we used to call this "Turtle Tipping" and I'm bringin' it back, baby!

Hint: Mushroom Houses

In New SMB Wii, you can make a bonus Mushroom house appear on the map by saving Toad when he appears in a level. To do this, you'll need to head to a level with the white Toad marker. Release Toad from the ? Block he's trapped in -- near the beginning of a level, listen for the cries -- and run him all the way to the end of the level to make a Mushroom House spawn. The type of Mushroom house depends on the final digit of the time when you grab the flag at the end of the level.

• Green (1-Up cannon game) - Get Toad to the end of the level, hit flag when the last digit of the time ends in 0, 1, 2 or 3.
• Red (Match game) - Get Toad to the end of the level, hit flag when the last digit of the time ends in 4, 5 or 6
• Gold (Star reward) - Get Toad to the end of the level, hit flag when the last digit of the time ends in 7, 8 or 9
