There are several variations of this game and I doubt ours is one of the ‘official’ ones. The idea behind it is that you have to find all the coloured balls you’d find on a snooker table, but as car colours instead. We start by spotting a red. Then we have to find a yellow then another red followed by a green, back to red then brown etc, etc. It always goes pretty well until we get to the ‘pink ball’, which takes quite some time.
Some people play where you have to spot 10 reds first then the colours in sequence, or with a time limit and miss a go/penalty points if you don’t get your colour. We keep it simple though.
This is a particularly good game for including younger children as they love just spotting different coloured cars.
