91 Pin Strike in Power Bowling Training

To get an automatic 91 pin strike in the last round of Power Bowling, Throw the ball on the right or left rail (depending on if you are right or left handed) so that it stays on it the whole time. If it reaches the end without falling off, you will hear a "click" and an explosion. Then all the pins will fall down from the shockwave. NOTE: This only works on the last round.

*
Play Golf without maps or meters

To disable the power meter, map, and the wind speed indicator, press and hold (2), then make a selection at the "Select a Course" screen.

*
Change the tennis court

To change the tennis court to the blue practice court, press and hold (2) at the warning screen that shows after selecting characters.

Silver Boxing Gloves

After you've beaten the Grand Champion, Matt, in a boxing match you'll be able to wear silver boxing gloves. To do so, hold (1) when the screen becomes black before a boxing match.

Mii Parade
You can add more Miis in Parade and audiences. Use Wii Sports to do it:

1. Make about 10 Mii's.

2. Transfer those Mii's to your Wiimote.

3. Delete the Mii's that are transfered to the Wiimote out of the plaza.

4. Start up Wii Sports.

5 When given the option of which Mii to use during gameplay choose the option to get the Mii from the Wii Remote.

6. After viewing the Mii's on the Wiimote back out by using the B button.

7. Exit out of Wii Sports and back onto the Wii Menu.

Now check the Mii parade and all 10 of the Miis that were on the Wiimote are in the parade. Now if you dont want the Miis on the Wiimote just delete them off. These Miis will now show up in all Wii Sports games that have an audience.

Scare Crowd in Bowling

To scare the crowd while bowling, start the regular motion for bowling and let go on the backswing. The ball will fly backwards and the crowd will scream and jump.
*
Amuse Crowd in Bowling

To make the crowd laugh in bowling, move to either of the gutters in your lane, turn into opposite lane, and bowl so the ball goes over the barier between the lanes. The ball will go into the gutter in the opposite lane and the crowd will laugh.

Master Bowling
In bowling levels, it may seem hard to get a strike, unless you have your own technique. My technique is only for right-handed people (Sorry lefties!). Okay, if you look on the ground, you can see dots near the point where you release your ball. Go to the very last dot, and click once to the right. Then, you bowl, but you release the ball when the Wiimote is angled downwards. You should see the ball curve towards the pins, hitting somewhere between pins 1 and 3. THis should either a) get a strike, b) take down most pins, or c) give you a split.
This technique should only be used on the first throw in a frame.
