Each Item can be used individually- whichever one happens to be in front of your Kart when pressing L/X is used (also, the one in the back of Kart will be used when pressing the L and down on the joystick, like a usual single Item.
OffenseA lot of attack power-ups in the Lucky 7 make for some great opportunities to damage opponents. The very sight of seeing a player flanked with weapons all around on the mini-map makes racers veer off to safety. The two Shells are pretty self explanatory, as well as the Banana and Bob-omb. (To see each of these Items' uses, be sure to follow their links.)
Although there is a lot of shields around you, the simple fact is that not all of these Items can block an enemy Item- some can be devastating for protection, like the Bob-omb. Most likely, you are going to want to use all of them in a vicious assault. Utilizing them as a battering ram against opponents (like Triple Green Shells a lot of times) is a very poor strategy, as they can hit your Bob-omb (which destroys both of you and your Items), or even worse, touch one of your boosters (Star and Mushroom)- that's right, be sure not to let rivals take advantage of your Lucky 7.
Three recovery Items are there to help boost you into a higher position, the Mushroom, Star, and Blooper. Using these at vital shortcuts and hard-to-navigate areas (difficult to predict when to use the Blooper, but great timing can lead to great results) instead of just rapidly pressing the Item button will get much closer to 1st.
Mario Kart Trivia
- In matches where the Item selection has been set to a single one, the Lucky 7 will produce seven of them... so you could find yourself with 8 Bob-ombs or a septuple Mushroom.
- Mario Kart 8 introduced the Crazy 8 in response to the popularity of the Lucky 7; joining the group was a Coin.
- Using all Items frantically is frowned upon by experienced players, as you can very easily blow up yourself or boost off a cliff.
- In Italy the Lucky 7 is called the Sette Portafortuna, basically a direct translation.
