Hot numbers in roulette

I'm not gonna name the site but I was looking at yet another person peddling their roulette strategy based on tracking numbers (no genuine advantage play).

Basically, you stick in the last 6 numbers and voila, it will tell you where to bet.   If the wheel spins 3, 4, 5, 14, 15 and 17.   You should probably bet on 19-36, cause those numbers are due....

Just for fun, let's see how that looks in the Excel Simulator

The Random Numbers

This is what my Excel Random Number generator produced (feel free to replicate this experiment yourself)

3, 14, 9, 9, 3, 21, 35, 3, 29, 0, 19, 36, 4, 9, 5

The distribution

Oh look the number 3 came up 3 times (surely that's a hot number)????  BTW, that was sarcasm.   We know enough about random numbers now to know that that can easily happen.  However this could be an interesting blog post in the future.   Hot numbers.

What might be more interesting is the ranges, which is what they were betting on in this system.


Their system was either avoid betting on 1 to 12 because it's hot.  but it might have been bet on 1 to 12 because it's hot.

There is no hot....  It's just some random numbers.   nothing is due or not due....

The kicker
And here was the kicker.  Don't worry, if you lose, just martingale and it'll recover your losses.

And we know how that ends...

Anyways, you know my thought on this sort of thing already.  I could type up their system into Excel and formally disprove it.   But you can always do that yourself if you want.

We know enough about random numbers, streaky numbers and martingale to know this is a silly strategy.

For more info on streaks, read my post on streaky coin tosses
For generating roulette numbers in excel, read my post (or look at the martingale one)
