100m Backstroke

100m Backstroke is an Aquatics Event that appears in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games. The objective of the event is to swim the 100 meters in the fastest time. The starting World Record for this event is 0:51.94, and the starting Olympic one is 0:52:54. The character set for this event is Girls, meaning that Peach, Amy, Daisy, and Blaze are playable.

Gameplay
The event is played by drawing circles on the touch screen within the marker shown on the top screen. The player has two circles to practice, before completing the rest of the length at a slower speed. Once they reach the end, they will turn around and do the second length at a faster pace. Each circle will be given a percentage based on how much of the player's line was in the circle, with 90% or more being Perfect, 70% or more being Great, 40% or more being Good, and anything under 40% being bad. The rating of the stroke affects the character's speed, with better ratings giving a greater speed boost. The speed that the final few strokes are performed at is decided by the rating of the last circle that the player drew.

Controls
