It is possible in "Bowling" to throw the bowling ball into the crowd, accompanied by a surprised reaction from the crowd (who scream and jump to avoid the ball) and an automatic do-over that does not affect the player's score. To throw the ball into the crowd, simply let go of the B Button during the back swing, and it will fly out of your Mii's hand and into the crowd.

Wii Sports has sold 81 million copies world wide. This outsells the entire Legend of Zelda series (70 million global sales across all games). This is due to the game being bundled with the Wii console.

In the training mode in the Bowling game, when you get to the last level in which you have to hit 91 pins, throwing the bowling ball in just the right position on top of the gutter will get you an automatic strike, accompanied by an explosion sound.

All of the golf courses in Wii Sports are remakes of levels from the NES game "Golf". Both games were launch titles for their respective systems.
