It was 5 years ago i played my first billiard on iPhone. It was by Lucky Clan and from todays view it was Old fashioned. But it had its qualities: 2 Minutes Time for a shot, no aiming lines, a really chat function, live watching of 2 People playing and so on. If you scratched, the Game was not lost because the pockets were small and even when only the Black Ball was left, it was often a hard battle. Today all has to be done fast and the aiming Lines make the Game totally different. Approaching Shots don't occur anymore.
