Kinect Sports

First off do this against the computer on champion because he gets a 246 just about everytime.

So the way I did this achievement was I got a chair and put like two big pillows (so it would register my arm better) just try different hight's on the chair. What you want to do is move the chair around until you find the "sweet spot"(the spot that you hit a strike over and over) what this method will do is give you a consistent throw. Limit all shoulder movement and don't ever stand up or move the chair once you find the spot. The only time you should/have to stand up is when you have to put you hands above your head, because it won't register you sitting until it has started. Stay consistent I can't stress this enough.

For me my sweet spot was a three-six inches or so to the left, I'm right handed, on the screen my hand would register one left of the center triangle and when I pulled back it would go to the center then on the push forward it would go back to the one left triangle sending the ball straight to the center for a strike everytime. On my release I aimed for the green light on the kinect sensor itself. This helps keep consistency.

I don't expect this to get positive votes but it should add slot of good and different approaches to the achievement. Hope this helps everyone get the achievement.

I have found a way to make this easily.

There is 7 marks on the track that help you aim your throw. You have to aim two rightmost points (if you are left hand then leftmost) then add spin and try to hit first pin to the right side. (if you are left hand then left side) This should cause very clear strike. When you have found the right place from which to throw then don't chance your place and throw always with same style. You have to also pay attention to throwing power. I could do it by relaxing and just throwing. Do not try to hard or slow throws, just relax and throw.

If you do this right you will get scores between 240-300 (expecting that you know how to pick spares).

this achievement is easily possible with the following technique

1.grab the ball with your right hand
2.stand in a position where the middle mark is lit up
3.pull your arm back and it will go 1 to the right
4.throw towards middle arrow

this technique is easily done and can often sting several strikes together. most i have had up to now is a seven bagger and got 250 that game but its best trying to do it while on champion as you could possibly beat the computer but if doing on champion its best to have a female opposition as they usually bowl between 230 and 270 i found but the males can bowl perfect games but not too often

One tip in addition to the other solutions regarding consistency. I had a hard time keeping direction and power consistent after I had found a "sweet spot", but then I started closing my eyes while swinging. This helps you to make relaxed and consistent swings. Pretty fast netted 251 points for this achievement and beating the computer on champion at the same time.
