Please note that this is the English version of the game. Wikipedia explains the differences in detail. Here is an excerpt:
In the version of pool or Eight Ball played in the United Kingdom and Australia, plain unnumbered red balls and yellow balls often replace the solid and striped balls. If not, the terms "bigs" (9-15) and "smalls" (1-7) are generally used instead. The black ball, however, still typically bears a number eight. Another difference is that the UK table has pockets just larger than the balls, whereas the American table has pockets significantly larger.
