This game is not Snooker. it is pool but using the coloured balls found on a snooker table.

Snooker is played on a much bigger table with smaller balls. It requires much more skill to play than american 8 ball pool. This is why many snooker champions also do very well in world pool championships. You rarely see (if ever) a pool champ win a snooker championship.

The potting sequence is red, then colour (the red stays down and the colour is respotted) once all the reds are potted then the colours are potted in the order yellow, green, brown, blue, pink and finally black.
