From the Super Mario Wiki
Snowboard Slalom is one of the microgames in the Sports folder in WarioWare, Inc.: Mega Microgame$!. It returns as one of Dr. Crygor's microgames in WarioWare Gold, in which it uses gyro controls instead of buttons.
There is a top-down view of a ski slope, with a large snowball in the middle and a goal at the bottom. The player must steer the snowboarder, coming down from the top, around the snowball and into the goal. The microgame is won if the snowboarder makes it to the goal. However, hitting the snowball or any walls will cause players to fail the microgame.
