does that mean the usual way of forecasting lottery won't apply to the 6/59 game?

First, my previous comment was specific to the UK lotto game. If you are not interested in the UK lotto game per se, ignore my comments.

Second, I hope you know that there is no reliable way to "forecast" or predict the outcome of any specific lottery drawing.

And none of the statistics like the ones at

https://www.national-lottery.com/lotto/statistics will improve your odds of matching a specific drawing.

(The only way to improve your odds of matching is to purchase more tickets, each of which is different.)

That said, you have to pick 6 numbers from 1-to-59

*somehow*. And any method is as good as another, because all combinations (tickets) have the same probability of matching a specific drawing.

My previous comment relates to the fact the UK lotto changed from 6/49 to 6/59 after 8 Oct 2015 (Thu).

But the statistics at

https://www.national-lottery.com/lotto/statistics cover "20 years". (Actually, apparently at least back to 27 Dec 1995.)

Consequently, some statistics are misleading.

For example, the 6 least-often drawn numbers are all in the 50s because those numbers were available to be drawn only in the last 400 of the 2465 drawings that are covered by the statistics. Well, duh!

For the same reason, the total frequency of the numbers in the 50s are significantly lower than 1-to-49.

In fact, IMHO, the only valid statistic is the "most overdue numbers", since that seems to mean only the most number of days since last drawn.

any idea what VBA formula or Excel function to use to get "hot", "cold" and "overdue" numbers?

It is certainly doable. Some statistics can be calculated with Excel formulas alone. Some are best done using VBA procedures.

Before anyone can help you, you need to specify the lotto that you are interested in, or its parameters.

Such calculations are fun. But I'm afraid that I should not take the time to participate.

Good luck!
