Jump Boost

A Trick (also called Stunt) is a technical move that first appeared in Mario Kart Wii. After being launched off of most ramps, or driving up the edge of the stage, characters can perform tricks. After performing a trick, the player will get a speed boost. Tricks can also be executed on Rainbow Ramps. Many basic tricks include the character looking backwards and waving or wagging their feet, but more notable tricks include Yoshi sticking out his tongue, King Boo shrinking and laughing, or Funky Kong's one-handed upside down flip.

Tricks reappeared for Mario Kart 7, with the same kind of properties and can be activated by pressing while going over a ramp. It was also known as Jump Boost, which is shown on the e-manual.

Unlike Tricks in Mario Kart Wii, Mario Kart 7 has only 2 variations of a stunt per character. For example, Luigi has 2 stunts. The first being an animation of him punching the air, and the second being Luigi flailing his arms about. In Mario Kart Wii however, Luigi has 6 stunt animations, 3 for bikes and 3 for karts. All stunts for each character for Mario Kart Wii can be seen below.

Tricks will reappear in Mario Kart 8. This time, there will be a new sound effect when a character performs one.

Trivia

 * In an American commercial for the Nintendo DS, the game Mario Kart DS is featured in a CG animation where Mario is performing a trick over a ramp. This is inaccurate, as tricks were never introduced in Mario Kart DS.
 * In Mario Kart 7, a Trick can be used to boost the flight ability and fly for longer than normal.
