Line in the Sand

Line in the Sand is a 1-vs-Rivals minigame featured in Mario Party 9.

Introduction
The rivals run into the sand pen, chased by the solo player. The solo player stops at the grassy area, and the camera focuses on the sand pen.

Gameplay
The solo player attempts to eliminate all other players by drawing shapes around them. If a complete shape is made, it will darken slightly, and any players inside its perimeter will jump up and be eliminated. If a player draws a line too long without connecting it, the beginning of the line will be erased. If even one rival survives the entire 30 seconds, all rivals win.

Trivia

 * This game's concept is similar to that of Etch 'n' Catch from Mario Party 3.
