My aim was to explain the author’s terminology for those who’ve never seen a table without pockets.
Snooker is played with 21 colored balls which must be pocketed in the correct order.
Billiards is played with 3 balls, 1 white per player (one has a black dot and the other doesn't) and a red ball.
Billiards table is bigger than the American Pool tables.
