Drag back from the cue ball to set the angle and the power, let go, and watch. The table is standard eight ball and the game does not explain itself, because it does not need to: everyone who has stood at a pub table knows what the triangle means and what happens if you sink the black early.
The whole thing rests on the collisions, and they are good. Balls kiss and separate the way they should, the cushions behave, and a shot played thin off the rail arrives where you aimed it. There is no career, no unlockable cue and no shop. There is a table, and you can be on it in three seconds.
