31 Days Of Roulette Gambling Tests

Back in April and May of 1971, the Englishman Patrick O'Neil-Dunne tested his own as well as other players roulette gambling strategies at a roulette marathon of 20,000 spins at roulette table number 14 in the casino in Macao - close to Hong Kong. With a staff of five, he wanted to test every recommended roulette system, including his own strategies that would prove that 'choices' play just as big a part in the results as do 'mathematical probabilities'.
No existing roulette gambling system did in fact give any return on the investment. For a long time he believed that a strategy where you bet on one column (12 numbers) would in fact work, but it too failed. His roulette gambling system was that he would first bet on a column when that column had not been hit for 6 spins in a row (called a 'sleeping column'), then he would play that column with the traditional Martingale system betting - first 1-2-4-8-16-34 through 6 spins. If he had not won by then, he would abandon the progression and start all over again - as keeping playing according to the Martingale progression would become too expensive.
O'Neil looked at the six spins as a tennis match - and for days his crew of gamblers did not loose many fights. The had made a big profit from this system. So perhaps this technique will work well in the short run - in the long run all the roulette gambling strategies will fail.
During the 20,000 spins - only a single time on every 100 spins did a 50/50 bet lose more then 8 times in a row (Example: The ball lands on a red number 8 times in a row). Such an event is a nasty experience for the Martingale and progression players in general.
O'Neil himself was a fan of betting on 'sleeping numbers'. That is numbers that has not been hit for a long period of time. He believed that once such a sleeping number was hit - it would soon be hit again. He had success with covering such sleeping numbers, especially the ending numbers like: 6-16-26-36. If these numbers had not been hit for 36 spins he would cover those numbers with chips.
After 31 days of roulette gambling and testing, the crew of roulette players ended up with a net profit of $191,148 - plus plenty of tips to the staff working at the casino. The bet sizes had been from $1 up to $500 per chip. Had O'Neil found the 'truth' about roulette? Most likely not. O'Neil himself claimed only to have been lucky.
But even being lucky can take a lot of hard work and planning. In the book 'Roulette for the Millions' (Chicago 1971), you can read all about how he planed the 31 days of roulette gambling and how he used those statistics after the gambling marathon was over.
