Testing Roulette Systems - The 300 System

The 300 gambling system is named after a certain amount of units which you bet in your initial stake; therefore this system is relatively demanding on the money.

The principle is quite simple: you bet 100 units on 1st 12 numbers and 100 units on 2nd 12 numbers and then you bet 10 units on all 10 of remaining 13 numbers including even zero. So just two uncovered numbers left and you still bet in the same way.

What do the statistics say?

If a number hits from the 1st or 2nd 12, you do not make a profit and at the same time, you do not make a loss (it occurs 24/37 = 64, 9% of the time). If you hit one of those 10 numbers which you bet on, your profit is 60 units (it occurs 10/37 = 27% of the time) and if you hit one of those 3 uncovered numbers, you lose 300 units (it occurs 3/37 = 8, 1% of the time).

Therefore the expected profit is 64, 9*0+27*60-8, 1*300 = minus 810 units per 100 spins. The system is supposed to go drastically below zero in the long term betting.

According to our test simulation a reality of this system correspondences with our statistical assumptions. Unfortunately, this is a horrible finding. We have attempted to apply a linear progression, it meant that after each losing series, we increased our bet size by 300 units until we made a profit.

In reality, it is impossible to wager such large sums of money due to certain table limitations etc. but we have decided to try this attempt at least theoretically.

No spectacular results were observed. This progression did not work well... So a huge slump was present, hardly any system could go so deeply below zero. We have also tried to apply «waits strategy».

We were waiting until one of those 3 uncovered numbers hit once or 2 times in a row and then we started betting using the basic version with no progression):

By using the wait factor of 1 the curve became a little serrated. The variance was very rapidly reduced, but the system still completely went below zero. By using the wait factor of 2, the system made «stairs» in the progression and the variance was very small and reached values of about 1.000 units.

Therefore, we could observe that with exception of some temporary incremental sections, this system went constantly below zero and did not make a profit in the long run. There was no point in applying the wait factor of 3 because of too long waiting periods (approximately of about 10.000 spins).

So then we have attempted to apply again «waits strategy» but we tried to add a linear progression (wait factor of 1 and wait factor of 2, as before) and progressions are shown on the following graphs:

So this was again unsuccessful and the system did not work so well. There was a big danger of huge losses. By using the wait factor of 2 we could even observe the upward trend and even if we managed to result in profit per even more then 100.000 spins, then a huge slump always occurred and the values plumped down.

The following graph shows another demonstration of the gentle progression. After each 10 losing series, we increased the stake by 300 units.

Unfortunately, this did not turn out to be successful either. This system needs a new progression, but we are afraid that this system appears to be hardly usable and we, therefore, conclude that this roulette betting system is completely impractical.
