The cover for Mario Hoops 3-On-3

Mario Hoops 3-on-3, also known as Mario Slam Basketball in Europe and Australia and Mario Basketball 3on3 in Japan, is a Mario sports game developed by Square Enix for the Nintendo DS. This time, Mario and his friends are playing basketball.

In the beginning, it was meant to be an original intellectual property, but Square Enix felt that it would work well if it were a part of the Mario franchise, and so Square Enix contacted Nintendo, who then allowed it to use the Mario label. This game is the first in which Mario and Final Fantasy characters appear together as playable characters.
