Synchronised Swimming (Duet)

Synchronised Swimming (Duet) is an Aquatics Event which appears exclusively in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games. The objective of the event is to score the most points by performing various moves in the water in time to the music. The event has a starting world record of 92.1pt(s) but does not appear in the game's story mode.

Gameplay
For this event, the player must choose two characters from the Heroes category, and compete against a team of the other two heroes, as well as a pair of Chao and a pair of Koopa Troopas. To perform moves, the player must press the A Button when two matching symbols overlap. Performing the move with perfect timing gives the player a higher point score and is indicated by the characters who performed the move having a rainbow sparkle. At various points in the event, the two symbols will swap sides, and the player must press left or right on the control pad to switch the sides of their cursor to be able to perform the move. Performing multiple successful moves in a row will earn the player combos, which will result in a higher score. The maximum combo that can be obtained by performing all of the moves perfectly is 60. Performing the move with the cursors the wrong way around, pressing the button at the wrong time, or failing to press the button at all will cause the player to fail the move and lose any combos they have built up.

Controls
1) Performance: Press the A Button at the right time. 2) Switch sides: Press Left or right on the +Control Pad.

Medley Match
In Medley Match mode, Synchronised Swimming (Duet) appears as the second event of the 2P Aquatics Medley, as well as the fourth event of the 2P A La Carte Medley and the third event of 2P Co-op Medley 3.
