Rail Riders is a 4-player and duel mini-game appearing in Mario Party DS. In this minigame, the characters slide down as speedily as they can on a piece of leaf down a handrail of the stairs, in order to jump the farthest distance off it.
This minigame is the first one out of the set in the game's Score Shuffle competition.
The minigame takes place on the stairs within a rich house, which is given an impression of looking massive to the player's perspective; the stairs seemingly lead down to to the foyer where the characters land upon a red rug. Various paintings can be seen in the background.
The aim of this minigame is to slide down as fast possible down the rails to pick up speed, which ultimately determines how far the character travels when jumping off. Use the stylus to slide the lower screen upwards, repeatedly and quickly.
