I would just like to know what was the percentage chance of it happening in James' game so I fully understand how amazing it was.

There are 319,770 8-box configurations. There are 165 combinations of eight different reds. Therefore the probability is (165/319770) = just over 0.05%.

You'd expect it to happen once every 1,938 games. We've had almost that many games (yesterday's was the 1,858th we've seen - the 1,859th to be recorded, but one was never aired), and we've had one all-red 8-box and one all-blue 8-box!

What game wasn't aired, KP?

Amanda's, due to the death of a relative between recording and transmission. A repeat of Kirsty's £75k win was aired instead.

Does anyone actually know what she won?

£13,500.

To keep on-topic here, she obviously didn't have an all-red 8-box, as hers contained 10p.
