The spin works how it is meant to. Maybe you are not hitting the ball hard enough to notice the effect. You can not spin a cue ball if you hit it softly.
Thanks for the feedback BlueDragon. I'm working on a 9-ball version - but thats a different game entirely! Btw there is a mute button on every screen. :)
You'll get used to the handling Zero94, but it takes a bit of practice.
Seafoam - the music works fine here, with the menu music fading out before the race starts. Strange that it's different for you - perhaps you have a different version of Flash Player.
