Single Sculls (or Rowing) is a real-life Olympic event in Mario & Sonic at the Olympic Games and the only one in the "Rowing" category. It involves pressing buttons together to speed up whilst doing the row action so the player can finish first.
All that has to be done is for the player to row with excellent timing as fast as possible to the finish line.
To play, only is needed. Players can press the button(s) specified on the screen and pull back. A green notes appears as bad result while a red note indicates a good result. At the beginning, mostly s and s appear, but as the finish line gets closer +s start appearing. When the finish line is close, the buttons disappear and all the player has to do is pull back the remote with good timing. Only four players can participate in this event, and the first of those four across the finish line wins.
To win Dr. Eggman's second mission, he must finish the race in second place.
In Princess Peach's third mission, Peach must win the race with at least three perfect strokes.
Constant skill, as well as raw power, is required to make the continual adjustments necessary to keep your skiff moving in a straight line. Work your way along the course and cross the finishing line before your opponents to win.
