Block and Roll

Block and Roll is a 1-vs-Rivals minigame featured in Mario Party 9. Its name is a pun on "rock and roll". The concept of this game is similar to Boulder Balls from Mario Party 3, except the roles have been reversed.

Introduction
The screen shows the solo player's destination. It then goes across the path to the solo player, who picks up a block. They begin walking, but a boulder knocks the block out of their hands. As the camera zooms out to show the rivals, the solo player grabs a new block.

Gameplay
The solo player attempts to transport three blocks to the other side, while dodging the rivals' boulders. After a rival rolls a boulder, there is a three second lag before that rival can roll another one. If the solo player is hit by a boulder, they will drop the cube, and must return to the cube source to get a new one. If there are only two rivals playing, the boulders that they toss are larger than those a team of three get when playing. The solo player moves more quickly when not carrying a block. If the rivals successfully prevent the solo player from transporting three blocks within 60 seconds, they are victorious.

Ending
If the solo player is victorious, the area begins to shake and a path across the gorge appears.
