Not a simple question, but this is two main reasons.
1) Brightness of the Star Play a part. Assume uniform Atmosphere.
2) The Atmosphere also another part. Assume stars of the same brightness.
1) Brightness of the Star Play a part.
Brighter the Star, less likely the twinkle. Look at the Moon, does it go Bink Bink? Too Bright.
But Dimer stars, under the same Atmospheric conditions, may Bink.
2) The Atmosphere also another part.
The Atmosphere is not uniform, look at the sky during the day, sometime, it clear blue, and other time clouds mass abound.
The Atmosphere is like a thin soup, with some sliver of bread in it,. using that example, when the Stars of the same brightness is in the Sky, imagine when a sliver of bread blocks lightly one of the stars, thus one Bink, and another don't.
It Real life, Stars are not of the same brightness, and the Atmosphere is not always uniform. making the issue complex.

The twinkling of stars is all the crap in our atmosphere getting in the path of the light coming from a star.

all stars twinkle some just are not visible with the naked eye the atmosphere causes what you see as a twinkle...its the same as the shimmer you would see in the air over a hot street, the difference is in the temperature and different layers of the atmosphere screw up the light

It's all becoz of refraction .The light comes to earth from all stars but due to bending of this light by the atmosphere (thats refraction) the stars seem to twinkle.
But the light of some stars get gets bended so much that it is sent back into the universe .As a result of this we aren't able to see some stars twinkle .

all stars twinkle, it just depends on the elements present in that star. OR those who don't twinkle my not be a star at all.

Twinkling is due to atmospheric refraction caused by atmospheric layers of gradually changing refractive indices. therefore distance is a major factor. This phenomenon also causes mirage and looming. May b the stars which u saw were comparatively closer or they can just b planets of our solar system.

Alll stars twinkle from our perspective the earths atmoshphere distorts the light coming off them and so they twinkle.

All stars twinkle. Those that don't are not stars, they're planets.

stars which are farther away from us seem to twinkle more due to more atmospheric refraction.stars which are nearer twinkle less due to comparatively less amount of atmospheric refraction.
stars which are far away are a point source of light whereas the nearer ones are an extended source of light.
