Kinect Sports

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 heights 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 made a video of how I was able to get the achievement. It is based on previously shared methods, bit I thought I could provide my own take on it.

WARNING!: Video may be loud.

DISCLAIMER! There is still a bit of luck with this achievement. The AI score varies wildly, but this should still get you a high enough score.

Don't like videos? Here's some text:
You'll want to find a square seated chair. Position your chair slightly off centered. As a righty, I sat slightly to the left so that my throwing arm was about centered with the Kinect. You should be seated about 2/3 meters away with the Kinect sensor at approximately chest height.

When you throw your ball, you'll want to keep as straight a line as possible. This is why you need a square seated chair. You should be seated right at the edge of your chair so that your arm can go straight down passed the seat. Begin by dragging your arm along the side of the chair and follow through to make a straight throw. I'm sorry if that isn't super clear, but that's why their is a video.

The initial movement of your arm determines the angle of the ball. By dragging your arm along the flat side of a square chair, you assure the ball goes straight down the lane. The second half of your swing determines curve. By beginning along the side of the chair, you set your arm on a straight course essentially negating any curve.

Doing this method gave me a winning score of 274. This was the second game I tried it. The first game we tied with a score of 267. Therefor, I can confirm a tie does NOT count as win.

Good luck, and sorry to be many years late.

On average the computer gets a 246, although the scores varied down into the 230's and up into the 250's. It probably wouldnt be a bad idea to work on this and the 250 game achievement at the same time.

If you have more than two open frames (non-spare or strike frames) you probably wont reach 250.

This is not really a solution but helpful suggestion.

I just got this achievement by doing the same exact thing with my arm everytime while bowling. what I would do would be starting at the second to last arrow on the right and then bring my arm diagonal across my body up towards my face while always finishing with my bicep on the right side of my nose(throwing arm side) after getting used to this motion it wasn't long before i bowled a perfect game. Yes there were time when i wouldn't get a strike or spare but you just have to keep working at it getting the same throw everytime. Good luck and I hope this helps anyone trying to get this
