set of 16 numbers selected in any manner will yield similar results is a valid conclusion and satisfies
the theoretical expected conclusion.
I do not believe that there are any biased wheels in use in any Australian or UK casino. It would be against
the casino's interest to allow any bias since an aware player could take advantage of such a situation.
I do not believe that any croupier using the modern shallow roulette wheels, is able to spin the roulette ball
so that it comes to rest in a predetermined slot or even predetermined section of the wheel. Many experienced
croupiers may try to impress you by claiming all sorts of historical tales. If a croupier was able to control
the destination of the roulette ball then after a short period of time, surely his friends and family would
all be wealthy. Over a period of time the same results would be obtained if an infinite number of different
croupiers had one spin each of the roulette wheel.
The roulette wheel is a mechanical device which produces random events, thus there is no validity in any method,
strategy or system which will purport to predict the next outcome since each roulette outcome is an independent
event.
For the interested reader, the following table sets out the frequency of each number over the 40000 roulette
spins. The 40000 spins were recorded from play at Launceston Casino over several sessions. Each sessions play
have been linked consecutively to give a continuous flow of 40000 consecutive spins.
The effect of time breaks do not effect the data. It would be in effect as though the roulette wheel was put in
storage between each session.
The following frequency table shows the number of times each roulette outcome ranging from 0 to 36 occurred in
the set of 40000 spins. The column headed TOT reflects the total frequency for each roulette number. It can be
seen that the number 0 occurred 1004 times whilst the number 2 occurred 1120 times. The longest gap between a
number occurring is shown in the last column headed L.

It can be seen that number 9 slept for 401 spins at one
stage during the 40000 spins. The theoretical frequency for any number would be calculated by dividing 40000 by
37 which is 1081or 2.7%

Comparing the actual results to the theoretical, it can be seen that there is a strong correlation.
Having said all this you may be wondering if I am negating my own belief that it is possible to use past
roulette outcomes as an aid to selecting a set of numbers to play in the future in order to overcome the
house percentage. In order to try to convey my theory I suggest you ponder the following.
Consider a bet on red only. The probability of winning is 18 chances in 37 or .4865, since there are 18 red
numbers and a total of 37 numbers. Suppose the consecutive roulette outcomes are recorded and after 50 spins,
red only resulted on 10 occasions. What would be your level of confidence that over the next 50 spins red
will occur 10 or less times?
