Roulette is a game of chance. It uses a spinning wheel with either 37 or 38 numbered pockets. The wheel is spun one way and a ball is sent round the other way.
Before the wheel is turned, players bet on where the ball will land. There are lots of different ways to do this, and the chances of winning and the payouts vary.
The first recognisable roulette game was played in a Paris Casino in 1796. The game is designed to give the casino an edge - in other words, over a long time players should lose slightly more than they win. That's how casinos can afford to have lots of smart people in suits standing around saying "Good evening Mr Bond".
Unlike Mr. Bond however, the casino is not always invincible. We're going to look at the maths behind roulette, and how new online casinos such as the ones listed at TheCasinoDB gain their advantage and how you can gain yours!
Here's how the sums work:
EUROPEAN TABLES (single zero)Most European tables have 37 holes numbered 0-36. The 0 is coloured green, the other numbers are red or black (18 of each).
One bet is to pick any single number. This pays out 35/1. Therefore if you put £1 on it and your number comes up, you will receive your winnings of £35 plus your original £1 = £36 in total.
However the chances of winning are 1/37 because there are 37 numbers and only one winner. This means if you play 37 times, it will cost you £37, and on average* you should win once which will give you £36. In other words, if you play for years and years, for every £37 you bet, you'll get back £36.
The simplest way to show this is to put £1 on every number, so that's £37 in total. Spin the wheel. The winning number will give you £36 back, the rest all lose, so you're £1 down.
The house wins £1 out of every £37 bet which is 2.7%. It might not sound like much, but when big money is flying around, it soon adds up!
* There is NO guarantee you will win one time every 37 games! You might not win any, or if you're very lucky you might win two or more. It's like throwing a dice six times. On average you should get one six, but you might get more, or you might get none.
Another common bet is Red/Black. This pays out 1/1 (or evens), so if you put £1 on red and it wins, you get £1 plus you get your original £1 back = £2 in total.
|Among the various games at casinos online or offline to choose from generally UK players prefer blackjack, roulette and table games. In Australia however the players there prefer playing online pokies (how they call slots in Australia).|
|Not everyone can work out the odds of winning at casino games, but if you put the maths aside and just play for the fun element and hope Lady Luck is on your side, then you will be able to enjoy a wealth of exciting online casino games right here.|
AMERICAN TABLES (double zero)If the European tables didn't have the green zero pocket, then there would be no profit for the Casino. American tables have a second green pocket, the double zero. This doubles the profits!
Some places do play special rules regarding these zero pockets, e.g. if you bet on all the odd numbers and zero or double zero comes up, they only take half your money.
How nice of them!
Let's see what the chances are on a double zero wheel:
HOW DO YOU WIN?
Answer: You don't - well not for certain!
There are stories of people who have won at Roulette but for everyone that wins, there are lots more who lose! Of course, there's fun to be had in trying a "system", so even if you lose a little bit, you've enjoyed yourself.
In the old days, some gamblers used to watch the same roulette wheels week after week, and very occasionally would notice a "bias" which made the wheel favour some numbers slightly more than others. By continually betting on these numbers, the gamblers turned the odds in their favour and started to win - until the management realised and mended the wheels!
The main rule about winning or losing is that you must set yourself a limit of how much you're happy to lose, and if it all goes then STOP!
SO HOW DO YOU WORRY THE CASINO?
That's what we put at the top of this page, and there is a method!
Imagine you're going in to play with £100. You have two choices...
If you play £1 a time for ever and ever, very slowly and surely your money will go, but if it's a nice place, then maybe it's worth it. And the casino will love you because even if you do happen to get ahead and then stop, it won't cost them much.
Of course if you put all your £100 on one number, you will probably have a very short visit... but the Casino will worry! That's because if you DO win it'll cost them £3,500. They won't like that!
So if it makes the Casino worry, then it has to be better for you!
A knowledge of maths is essential for anyone looking to get an edge in gambling. Whether itís understanding probability to gain an advantage in poker, understanding odds and making quick calculations at table games or more advanced things like specific betting strategies such as Kelly Betting.
