Roulette systems

from Wikipedia, the free encyclopedia

Roulette systems are methods that aim to achieve a systematic profit for the player at roulette . Attempts to develop such systems have been going on for over 250 years. Permanent winning at roulette is not possible.

Practically successful roulette systems use statistical deviations, such as cup errors . A roulette table has to be evaluated for a long time in order to recognize which numbers come up too often. Due to mechanical manufacturing tolerances , no table is stochastically perfect. Other practiced methods use a camera combined with special detection and prediction software or manual triggering of a technical mechanism to measure the speed . Players who use such methods are often banned from the house and then move to the nearest casino using the same working method.

The best known system is the Martingale system ( Martingale game ). With this roulette system you place a "50:50" chance (e.g. red / black, pair / impaired or manque / pass, with zero division: 49.325%: 49.325%) in the event of a loss, and double the bet starts again in the event of a win. With a starting bet of z. B. 1 EUR the stake in the tenth round is already 512 EUR. Over several rounds, the total profit with this roulette system is only ever as large as the starting stake. In the event of a loss, however, you lose the entire capital. In addition, this strategy is usually limited by table limits. Although this system inevitably leads to bankruptcy after a period of time, it is the most popular roulette system because inexperienced players believe that a chance will not repeat itself as often.

For each type of loss progression, the mathematician has closed Koken mathematically or determined an “allowed game route” through computer simulation , for which the probability of a positive game result does not fall below a specified limit value . A probability of win of 75% assumed for the “permitted route” means a risk of 25% for the total loss, which is considerably greater than the expected profit.

Choosing the right standard bet

Although at first glance all standard bets have a balanced stake / win ratio, there are differences at second glance.

These result from special regulations that the game organizers (casinos, clubs) introduced (deviating from the classic roulette game rule that the brothers François Blanc and Louis Blanc created in Europe) and they result from customary game fees on certain odds groups.

  • In the case of bets on individual numbers (plein), in the event of a win, it is expected that the winner will leave the casino employees a simple bet for plein or half a simple bet when betting on two adjacent numbers (cheval) as a tip. In the "classic game" (also: "big game"), tips are usually collected in a special container at the table, called a tronc . In the case of the "slot machine game" (also: "small game"), the Tronc is withdrawn automatically in the event of a hit. This reduces the profit to 34 times the stake.

The bet-win-ratio is therefore worsened by 2.7% for bets on "Pleins" compared to other standard bets.

  • For bets on "single chances" ( red, black, even, odd, manque or passe ), the rule for European game organizers is that when the 0 ( zero ) or 00 ( double zero ) appears, the stake in the classic game compared to the Standard betting is not entirely lost; He is subject to the so-called "blocking", in which half of the stake for the following number draw remains as a 'blocked' bet on the respective chance and, in the event of a hit, participates in the game in full again (or the player lets "split" and he half of the stake is paid out without participating in the subsequent draw, the other half of the stake remains with the bank). This special regulation improves the bet / win ratio by 1.35% for "simple chances" in the "classic game" (mechanical roulette on croupier-operated tables), but not in "machine roulette" (semi or fully automatic computer roulette with or without croupier-operated bowl) where the principle of total loss when the 0 or 00 appears is generally pre-programmed. Participation in roulette in the "slot machine game" with zero and double zero means a 4.05% higher risk for the player than in the "classic game" with a zero.

With regard to the special rule-related conditions, the win / loss ratio in the "classic game" on "simple chances" is mathematically more advantageous than on all other chances, while this is not the case in the "slot machine game".

Since both in the "classic game" and in the "slot machine game" the tronc deduction is made on pleins, the profit expectations for standard bets are in any case lowest with stakes on "pleins".

Thus it follows that

  • that participation in the "slot machine game" is in any case less favorable than in the "classic game" due to the lack of zero rules there.
  • that standard bets on "Pleins" and "Chevals" are mathematically more disadvantageous than on any other odds.

This computationally undisputed fact should be taken into account in particular with the bet combination, which is made up of several standard bets, as the bundling of standard bets on a "simple chance" (e.g. manque or pass ) can result in a strategic advantage here .
