Once Albert Einstein said: “No one can win at roulette unless he steals money from the table while the croupier is not looking.” But this utterance is not correct in some part because it is still possible to apply some rules of probability theory, try to calculate your winning odds with the help of helpful services or apps, see what to expect, and probably win.
It is a well-known fact that roulette is a game of chance, and when you know your chances to win, it seems to be a perfect moment to put your money on a certain colour or a certain number. This article will try to save your time explaining the math behind roulette and the best way to calculate your winning probability at roulette.
Winning Roulette Probability and the Math Behind It
Hundreds of thousands of people believe a magic mathematical trick can help increase odds at roulette and make real money. Mathematic is the most apparent approach by the help of which you can attempt to outplay roulette because many roulette systems are based on mathematical sequences.
In roulette, the wheel is split up into 37 equal parts. 36 out of 37 parts contain numbers starting from 1 to 36, and the last one is zero (in the American version, there are 38 cells, and two of them are zero and double-zero). The casino’s advantage is provided because of this zero, and in the American variation, it is ensured due to the additional double-zero cell. You have many opportunities to make your bet by choosing a black or red colour, picking odds or evens, or predicting a certain number(s). The last option is the most lucrative one compared to others.
If the wheel features no zero (and double zero) cells, the winning probability for a player will remain 18/36, or 50 per cent. But due to one more zero spot, this probability shrinks to 18 to 37. In simple words, the game has an “additional” safeguard of making a profit for a casino – 37 to 1, or 2.7%. In American roulette, the divergence is twice as large and composes 5.4% because of the double-zero spot.
When a player selects a concrete number, the gambling house also remains with a profit, even though the winnings appear to be magnanimously paid at the rate of 35 to 1. The player’s odds of losing are 36 out of 37, and the probability of meeting success is 1 to 37 only. That is, from each dollar bet on a specific number, the gambling house will get 2.7 cents or the same 2.7%. This data does not denote that the players always win, but they have fewer chances of leaving with extra money than losing the existing amount. But what is the best and easiest way to calculate your probability at roulette?
