The first and the most common mistake is not setting a bank roll limit.When you go in the casino take only that sum of money you can afford to spend and leave the rest of your money and all credit or deposit cards at home. If you have spent all the money you had you’d better leave the casino and occupy yourself with something different. When you choose a certain game to play at the casino, you should know well in advance exactly how the game works and how to play it scientifically so you win more money. Sometimes players choose games they don’t know well enough and as a result they lose instead of winning. The casino loves to fill their guests and customers with free booze of all types and kinds. Drinking impairs your judgement and gets you emotionally involved within the game thus losing feels worse, and most importantly you won't be able to play using scientifically proven strategies that shrink the odds of the casino winning. The third mistake is drinking while playing casino games. The only advice here is to avoid drinking in casinos. In differebt casinos players win differently. Maybe you play in a wrong casino. You can always find a better casino with better odds, bonuses, promotions and conditions for players. Players who haven’t work out their own strategy of playing think that the way other gamblers play can help them to win.This is a very serious mistake. Play your own way and never stick to strategies of other gamblers.

The European wheel - also known as the Single Zero roulette or sometimes French Roulette is very similar to the American wheel.
The European wheel has only a single zero while the American one has a single zero and a double zero, and that is main difference between them.
The European table is more beautiful in symmetry while the American table is more practical during play because the red/black and odd/even are placed right next to each other, and the first18/last18 betting spots are placed right next to the single numbers.
The European single zero offers the player better odds than the American wheel with it’s single and double zero.
American roulette wheel consists of 38 numbered slots: numbers 1 to 36, a zero, and a double zero. The betting layout consists of every individual number as well as a host of "outside" or combinations of numbers. After the players make their bets the dealer spins the wheel and a ball and after several seconds the ball will land in one of the numbered slots.

Roulette is a wheel game. The wheel placed in a bowl spins on an axis. There are 37 or 38 numbered slots on the wheel, an American roulette wheel contains 38 slots, a European roulette wheel - 37.The numbers can be black or red. The 0 or 00 are green.Up to 8 people can play roulette at the same time.Accordind to the rules the croupier spins the wheel of roulette in one direction and then rolls the ball around the edge of the wheel in the opposite direction.After the ball had fallen at one of the slots and stopped, the croupier announces the winners.The aim of roulette is to guess the number of the slot in which the ball will stop and to make the right bet. Before you start game, you buy chips from the croupier, and roulette chips are almost always different from all other chips in the casino. Each player has chips of his own color that's why the croupier knows who to pay off at the end of each spin. Players can make their bets until the croupier announces, "No more bets."After the result of the spin is determined, the croupier puts a marker on top of the winning number on the table.The marker is placed on top of the chips, if there are bets on that number. The croupier sweeps off the table all losing bets and pays off the winning bets.
In some casinos there exist some special rules.

In Prison/En prison
When the ball falls on zero, red/black, odd/even and first half/last half bets will not be collected by the croupier - instead they will have to stay on the table - in other words they are in prison. In the next spin the players have a chance of winning their original bet back - if their bet wins they will get their original bet back but with no additional win. If the ball should land on zero once again the bets will remain in prison one more spin and so on. In prison rule is a considerable advantage for players because the house edge is reduced to 1.35%.

La Partage
In case the ball stops at zero slot, the croupier will not fully collect red/black, odd/even and first half/last half bets. Only half of the players’ bets will be collected - the rest will be returned to the players. As well as the In Prison rule, the La Partage rule also reduces the casinos edge to only 1.35%.

The wheel is unbalanced.
Unbalance wheel is a good thing for unfair gamblers. They turn it to their advantage in order to make some fast cash. The only problem is that today it is impossible to find and unbalanced wheel. The story of Jaggers is well-known among casinos, that’s why they examine the wheels all the time. The casino staff examine the wheel every time before gamblers begin to play. In the case of an unbalanced wheel they recalibrate it at once.
2. The number that haven’t been hit yet is more likely to come out.
This is absolutely false. The probability to hit a number every spin is the same 1 out of 38. If the ball hasn’t landed in this very number for a long period of time it doesn’t mean that it is more likely to do it in a short while. Roulette is a pure game of chance. With every spin the chances of hitting any number are 38:1.
