The red/black system is a form of Martingale (double up on successive bets) system and is one of the better known roulette systems around. Your bets for this system are on either red or black, with your pay out 1 to 1 (i.e. double your money for a win) It is worth bearing in mind that your chances of winning each bet are just under 50/50 (remember the 0 and 00 that gives the casino its advantage)You begin by choosing a colour and placing your bet on either red or black. Be sure to make your first bet a small one. If you win, keep your winnings and place your starting bet again. If you lose, double your stake and place a bet on the same colour again. If this bet wins, your net result after two bets is the same as if you had one you initial bet. Keep your winnings and begin with your starting stake again. If your second bet loses, double your stake again, and continue doing this until your colour does come up, at which point your net win from the string of bets will be the same as if you won your starting bet.Now you know why it is important to start with a small bet. It doesn’t take too many losing bets in a row for your bet amount to climb to quite a big number. But keep your nerve, the key is being prepared to continue to double up until you have a win. Also be very aware of the table bet limit - if you reach this before you have a win then you stand to lose a considerable amount.

Pair
A single pair is the second lowest hand. This is when two cards have matched numerical value ace-ace being the highest hand two-two the lowest. If there are equal pairs when comparing hands then you compare the high cards of the matched hands.


Two Pair
Two Pair is two cards of the same rank with two cards of a different rank. A pair of aces with a pair of kings is the highest two pair if the highest pair are equal when comparing hands then the low pair is matched if that is the same then the single card decides.


Three of a Kind
Three of a kind is three cards of the same rank plus two other cards. When comparing hands the highest three set wins so A-A-A (the highest) beats all other Three of a kinds. This hand is also known as a set of trips.


Straight
A straight is five cards in a numerical sequence 2-3-4-5-6, these cards can be of any suit. When comparing hands the highest card wins so A-K-Q-J-10 is the highest possible straight. An ace can be low or high but not in the middle, so A-2-3-4-5 is ok but Q-K-A-2-3 is not.


Flush
A flush is made of any five cards which are the same suit (i.e. spades) when comparing hands the highest card is used to decide.


Full House
A full house consists of a three of a kind and a pair. When comparing hands it is the highest three of a kind that decides. The highest full house is three aces and any other pair.


Four of a kind
Four cards of the same rank (and a fifth card) Four aces is the highest example of this and four two's the lowest.


Straight Flush
A straight flush is five cards in a sequence all of the same suit, such as A-2-3-4-5 all of the same suit is the lowest straight flush

Royal Flush
The Highest possible straight flush and highest hand in poker. It consists of ace, king, queen, jack, ten, all in the same suit.

The numbers 1 through 36 are divided evenly among red and black "pockets". The pocket is the container that a ball may come to rest in. In addition to the 36 red and black pockets, there are either 1 or 2 green pockets, containing the number zero and double zero (00) on the roulette wheel. A close look also reveals that the numbers are not distributed in a random fashion. An attempt at order has been made, but is it relevant to the statistics? If no roll is dependent on any preceding roll, then how could the relative position of the numbers affect the balls resting position? The fact that you can bet on more than the individual number, and that each pocket has added attributes for wagering on counters this line of thinking. A balance between red and black, high and low, and odd and even is sought by the wheel makers. For every number on the wheel, directly across from it is the next highest even number. Black and red alternate, pairs of even numbers alternate with pairs of odd numbers (with 0 and 00 exceptions) This roulette wheel design is standard within the industry. A roulette dealer (usually referred to as "croupier") spins the wheel counterclockwise and releases what is usually a plastic ball along the track that runs along the top of the wheel's cavity. As the wheel loses velocity the ball is pulled down off of the track and bounces around until it settles into a pocket. There are a million small buffers and bumps to ensure that the ball is tossed around a good bit randomly before it finds a home.
