A:AnswerAccording to what Nintendo has told the press, it's designed to work on some carpets, but may not work on all. It seems their primary concerns with functionality are particularly long or thick carpets (like shag carpets, for example).
A:AnswerThere is no track included with the set. The camera on the car maps out a digital track using augmented reality. However, two cars can race together at the same time.
A:AnswerNo, you do not need a Luigi Kart in order to play with 2 players. All of them could be Mario. Also the max players in order to play is 4 Players.
A:AnswerThe maximum is regular bluetooth range, about 30 feet. there are 4 gates that you can set up wherever and then you map out the track by driving through them but you can do as many turns and straight aways as you want as long as you go through all for gates and end a lap where you started.
A:AnswerIt for sure works with the switch as that is what we are using for ours. A would only assume it works with the lite, you just need to be able to digital download the game to use this cart.
