A snooker table has six pockets, one at each corner and one at the center of each of the longest side cushions. The pockets are around 86 mm (3.5 in), though high-class tournaments may use slightly smaller pockets to increase difficulty.
There are 21 balls in a set of snooker balls, 22 if you include the Cue, 15 Red balls worth 1 point each, and 6 other colored balls worth different amounts of points, yellow (2 points), green (3), brown (4), blue (5), pink (6) and black (7).
