The name of this system (the Double 10) is derived from the way to gamble. You choose one certain number and you bet on that. To start playing, you bet 1 unit and on each 10th unsuccessful spin, you double the bet size as long as you hit the certain number. Then you reset the game back to the beginning and you start to bet again 1 unit. Simple but very prolonged.
What do the Statistics say?
It is not possible to express this system precisely mathematically, it would be very difficult, but the statement that on average the certain number should hit every 37 spins is enough for us. As well there are realistic exceptions as the certain number can even hit every 200 spins and more. Let’s see the progression (for our needs was necessary to apply some limitations as a maximum number of the spins in one series, let’s say to 100 spins, because by using the Martingale progression a very huge dispersion of the values occurred, therefore it would not be possible to work with it).
We have attempted to apply a progression series. It means that after each losing 100 spin series, we increased the bet size by 1 unit as long as we made a profit.
the Double 10 system in this form is not recommended in the long term betting as the system needs surely some kind of modifications such as applying another progression or some wait strategy (unfortunately the effectiveness is not supposed to be such a big due to the fact that a very huge dispersion of the intervals between the numbers occurred – in other words the same number can hit 2 times in a row as what as it can hit once per 200 spins....).
