##### Bias and Hotnumbers
« on: April 14, 2014, 10:00:14 AM »
The high standard of fabricate engins I cannot immagine me a biased wheel. 100k spins ary not enough to detect a bias. From this point of view it is useless to look for a bias roulette.

If there is a bias  the hotnumbers or the hotspots are the triggers.

In the most casinos  histories boards are used. They show the last 15 numbers, %5 red/black/zero of the last 50 spins, the hotest numbers of the last 500 spins and the coldest numbers.

What is a hot number?

On 500 spins every number falls on everage 500/37=13,5 times. The 4 numbers with the highest figure are called as hot.

In small samples the deviations are often very big.

In my casino it is not rare a number is hot and cold. For example a number has fallen in the first 300 spins 16 times and in the next 200 none. The number is hot and cold.

It is very dangerous to play on the hot or the cold numbers. I cannot recomment such strategies.

Here I show you the stats of a 50 spin sample. These diagrams are made on the history board of the multi roulette in my casino.

On average on 50 spins 8 numbers have not fallen. The deviation between the numbers is very big.

For the neighbour players it can be intetested that you see very often  one and two numbers with one neighbour has not fallen.
With low risk you can play such numbers also with a progressive betting scheme.

Hello dobbelsteen,

This is indded a very good and interesting point you make there.
Though this is not reason to stop researching this area of roulette called hot numbers

In general the 4 hot numbers has the highest occurence. The problem for a system is , that the 4 hot numbers change during the trial. A simulation program is very very difficult. A hit and run trial with a suitable progression is likely the best

They most certainly do change!  I find it much better to work with an aggregate as my primary focus and then just monitor the individual number performance from within it.  The aggregate also changes!  I find that it lasts much longer than inidvidual hot numbers though.
