Singles is a real-life olympic event. It is played in Mario & Sonic at the Olympic Games and the only one in the "Table Tennis" category. The first player to reach eleven points (five in the DS version) wins the game. It has a Dream version, called Dream Table Tennis, where Special Attacks can be used.
 Wii controls
Swing the Wiimote to hit the ball, press the B Button to hit the ball hard but have a chance of missing and press the A Button to hit it soft but have a greater chance of getting it. A point is awarded every time the opponent misses the ball or gets it out. To win the game, reach eleven points before the opponent does. The losers of the first game face each other for third and fourth meanwhile the winners face off for first and second.
 DS Version
Knuckles once again has a mission in singles except this time it is his fourth mission. He must gain eleven points before his opponent but he must also use a smash move five times.
Singles is Blaze's first and easiest mission. She must simply continue hitting the ball back and forth for ten shots. Her partner will most probably hit it back to her so it is up to her to keep up the rally.
Singles is not only Blaze's first (and easiest) mission, it is also her final (and hardest) mission. It is where she faces her Mario-series enemy while her enemy has some sort of boost. Blaze's enemy is none other than the tomboy, flower-girl princess herself...Daisy! Blaze must defeat Daisy while she is in top condition. The trick to beating Daisy is hitting fastballs.
Luigi has his fourth mission as singles and his mission is the same as Knuckles' except for two tiny differences. Instead of using smashes, Luigi must use spin shots (hold A while swinging) and he must use those spin shots to actually gain a point. In Knuckles' mission, Knuckles must only use them.
This is Yoshi's second mission. It is in the DS version of singles, to win he must gain eleven points (winning the match) before his opponent gains even three points. It is surprisingly hard for a second mission mission but if Yoshi is careful, he can easily win.
 Wii Version
Knuckles' fifth mission in the Wii version of Mario & Sonic at the Olympic Games is singles. To win his mission he must gain eleven points before his rival does, therefore defeating his rival. His rival for this mission is the fiery princess Blaze.
Like Knuckles, singles is also Bowser's fifth mission in the wii version. The criteria however, are different. Knuckles must simply gain eleven points before his rival does but Bowser must both gain eleven points before his rival but there is an extra condition, he must smash the ball (hold B while swinging) a total of seven times.
Singles is Wario's first mission in the wii version. This mission is really easy, all Wario has to do is rally (pass back and forth) a shot twelve times. The biggest difficulty here is the opponent missing the ball when it comes to them. A remedy for that is to hold A while hitting to do a slow shot.
Daisy's sixth mission adds a twist to the game of singles, it is her hardest mission and is found in the wii version. The pointing system in this mission is different as here, Daisy must gain only five points. The hard part of this mission is that points can only be gained by holding B when swinging, in other words, smashing the ball.
The fourth mission in the wii version for Yoshi is singles. To win he must do the same thing as Wario had to do in his fifth mission; continue a rally. The only difference between this mission and Wario's mission is that in this mission, Yoshi must rally three more times for a total of fifteen times.
