Line in the Sand is a 1-vs.-Rivals minigame featured in Mario Party 9. The name is a play on the phrase "line in the sand," meaning a point of stopping.
The solo player attempts to eliminate all the other players by drawing lines in the sand around them. If a complete shape is made, it darkens slightly, and any players inside its perimeter jump and are eliminated. If the solo player draws a line too long without connecting it, the beginning of the line is erased. If the solo player eliminates all the rivals within 30 seconds, the solo player is victorious. If at least one rival remains after 30 seconds are up, the rivals are victorious.
Rules – "The solo player must eliminate the other players by surrounding them with lines in the sand."
Controls (Solo) – "Hold the Wii Remote vertically. Hold while pointing to draw a line in the sand. Keep drawing to create a circle around the other players."
Controls (Team) – "Hold the Wii Remote sideways. Press to move."
