A Rocket Start is a technique introduced in Super Mario Kart and featured in every Mario Kart game since. It allows racers to rocket out of the starting line at high speed, gaining a head-start over any racer that simply drives out of the starting line. The technique was given a name in the instruction manual for Mario Kart 64. Similar to Mini-Turbos, Rocket Starts all vary slightly from game to game. You must press the Acceleration button at different times during the Pre-race Countdown. In Super Mario Kart, the Rocket Start is performed by accelerating (holding the B button) right after the first starting light goes off. This "revving" type of Rocket Start would reappear in later games. In Mario Kart 64, the Rocket Start is performed by accelerating at the moment before the starting lights turn blue. In Mario Kart: Super Circuit, the Rocket Start is performed by accelerating right before the final light appears, simalar to Mario Kart 64's way of Rocket Start. In Mario Kart: Double Dash!!, the Rocket Start is performed by pressing the A button the exact moment after the lights turn green. Repeatedly tapping the A button will almost always yield a Rocket Start. When in Co-op Mode, if both players press A at the same time at the right time after the light turns green, a Double Dash is performed, yielding an even bigger boost of speed than normal. The kart's exhaust pipes will spit out blue fire when the Double Dash is performed. In Mario Kart DS, Mario Kart Wii, and Mario Kart 7, the Rocket Start is performed by accelerating when the number "2" begins to fade out. It is also possible in Mario Kart 7 to get a Super Rocket Start. However, on the Wii, the numbers don't "bounce back" like on the DS and 3DS, giving you less time to press the acceleration button.
