Roulette online: varieties and rules of the game

Roulette is one of the most famous games of chance, in the classic version of which you need to guess which of the numbered cells located on a spinning wheel will fall into a ball launched in a circle. In classic roulette, the wheel is marked with numbers from 1 to 36, as well as “0”, aka “zero”. Drop bets are placed on the gaming table, which also contains numbers from 0 to 36 and additional betting options.

It is generally accepted that roulette was invented by the great French mathematician Blaise Pascal, but there is no documentary evidence of this. Although it is French roulette that is considered the mother of all roulettes. To date, there are already more than 10 varieties.

European Roulette : Rules and Bets

The European roulette wheel is divided into 37 even sectors, in which numbers from 0 to 36 are mandatory. Not everyone knows that the numbers on the roulette wheel are not in order (0, 1, 2, …, 36), but out of order. In roulette, cells from 1 to 36 are colored in two colors – red and black, and the colors alternate, and the sector with “1” is always red. Zero is green. The probability of hitting zero in European roulette is 2.7%, i.е. in any case, the casino is guaranteed to take all bets with such a probability.

European Roulette

European roulette is considered classic. Bets are divided into 2 types: external and internal. The former involve bets on red/white, even/odd, and groups of numbers. The second involves betting on a specific number, on two adjacent numbers, on a series of numbers on the roulette table. Here are some of the bets in European roulette (their common names in English are given in brackets):

  • to a specific number (Straight Bet);
  • to an even number (Even);
  • to an odd number (Odd);
  • to “red”;
  • to “black”;
  • on one of the dozens: 1 to 12 (1 st 12), 13 to 24 (2nd 12), 25 to 36 (3rd rd 12);
  • to small numbers: from 1 to 18 (1-18);
  • to big numbers: from 19 to 36 (19-36);
  • into triplets of numbers: “1”, “2”, “3” or “4”, “5”, “6”, etc.

The list is not limited to this and you can bet on the field where the numbers equivalent to roulette are placed, for example, on columns (1, 4, 7, 10, …). The biggest win can be obtained by placing a bet on a specific number, because the probability of winning in this case is minimal for the player.

In European roulette, there is also the “First Four” bet, when the chip is placed on the line separating the “zero” and the numbers 1, 2, 3. Thus, 4 numbers are involved in the bet, and the payout for this bet is 8:1.

European roulette, being a classic variant, is presented in almost all online casinos, a list of which can be found on this page – casino rating.

American Roulette: Rules and Bets

American roulette has one important difference from European roulette – the presence of another green section with two zeros, which is called “double zero”.

If the ball hits this sector, the casino also takes all the bets. “Zero” and “double zero” are located on opposite sides of the wheel. The presence of “00” allows you to increase the probability of winning the casino of all bets up to 5.26%. True, in some American casinos there is a rule: bets like “on red”, “on black”, and on those in which the probability of winning is about 47.37%, when “double zero” falls out, the casino is not completely taken, but only in half , i.e. half of their bets such a player receives back.

Pay attention to the probability of winning in the region of 47%. In many Internet publications, the probability of winning “on red”, “on black” is estimated as 50/50, i.e. fifty%. This is not true, we must not forget about the presence of “zero” and “double zero”. Therefore, the probability of winning, say, “for black”, is (18/38) * 100%, which is just about 47.37% (18 is the number of black sectors, 38 is the total number of sectors on the roulette wheel). In European roulette, the chance of winning “on black” is (18/37) * 100%, which is approximately 48.65%.

In addition to the same bets that are in classic roulette, in American roulette you can bet on the five numbers “0”, “00”, “1”, “2”, “3”, as well as on triples of numbers, where there is ” zero” and “double zero”: “0”, “1”, “2” or “0”, “00”, “2” or “00”, “2”, “3”.

French Roulette: Rules and Bets

French roulette is considered the ancestor of all other types of roulette. The wheel in it is no different from the wheel in the European one (or rather, vice versa), but on the table in the classic version, the inscriptions are in French and the table itself is somewhat different from the European one. In fact, many online casinos duplicate French words in English.

Since one of the two special rules described below can be used in French roulette, the player’s probability of winning is increased to 48.65%, and the probability of losing is reduced to 51.35%. That is why the house edge here is the lowest (2.65%) compared to European (2.75%) and American (5.2%) roulettes.

French Roulette

Rules and rates:
Here are the bets with their French names (the payout ratio is given in parentheses):

  • to a specific number – En plein (35:1);
  • to two neighboring numbers – Cheval (17:1);
  • three numbers in one row – Transversale (11:1);
  • four numbers in one square – Carre (8:1);
  • on two adjacent rows (three numbers each) – Sixainne (5:1);
  • on the column (column) – Colonne (3: 1);
  • for a dozen – Douzaine (3:1);
  • to an even number – Pair (2:1);
  • to an odd number – Impair (2:1);
  • on “red” – Noir (2:1);
  • on “black” – Rouge (1:1);
  • for small numbers (from 1 to 18) – Manque (2:1);
  • for big numbers (from 19 to 36) – Passe (2:1);

Examples of bets can be viewed in the above section about European roulette, because they are no different, except for the names. And now about the above rules.

“Partition rule” (“La Partage”) – return to the player in case of loss of “zero” half of his bet, if he made a bet with equal chances (“red-black”, “even-odd”, “small-big”). For example, by betting $22 on “even”, in case of “zero”, the casino will take $11 for itself, and return $11 to the client.

“Prison rule” (“En Prison”) – in the case of a bet with equal chances when zero falls out, they do not go to the casino or the player, but remain in place until the next spin (wheel start), and if it wins, then the player receives back his amount, and if he loses, then the money goes to the casino. For example, with a $50 bet on even and a $10 bet, zero comes up on number 13. Then $10 goes to the casino, and the $50 bet on “even” remains on the gaming table. No one has the right to remove it, increase it, etc. The wheel spins again and the number 20 falls out. In this case, the player is returned $50. If, say, 15 were rolled, then the player would lose this amount completely. Separately, a case is stipulated if “zero” falls out for the second time in a row. Such a situation is described by the rules of a particular gambling establishment, and in this case, the player can either lose the bet or stay with his own or even get a win.

By the way, from the point of view of probability theory, the chances of winning (as well as losing) are the same in La Partage and En Prison.

Three Track Roulette: Rules and Bets

This is another online variation of European roulette. Her wheel consists of three tracks, one inside the other. The rotation of each track occurs independently of the others, and each of them has numbers in sectors.

Depending on the implementation, options for the game itself are possible. For example, the ball is launched in the same way as in the classic roulette, but only on the inner, third track, the cells “catch” the launched ball. Perhaps there will be a separate fourth fixed sector for the ball. One way or another, after a complete stop of all tracks, the numbers on each track, opposite which the ball stopped, are considered winning. Bets on the game are made at the rate of one bet for each track. Thus, if you use online roulette to bet on, say, “even” or “odd” a $10 chip, then the bet on the table will triple, i.e. $30 will already be put on the line, i.e. $10 for each track.

As mentioned above, since this roulette has 3 rotating sectors, if you choose a bet of $5, then your bet will be automatically multiplied by 3, i.e. $15 will be at stake. So if you want to bet $3, then you put a $1 chip on the table, after which it will automatically triple. Another feature of this roulette is the variety of bets, where, in addition to the standard ones, there are bets like “red dragon” – “black dragon”, as well as “red splits” – “black splits”:

  • The “red dragon” bet is a bet on the numbers 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, 34. It looks like a dragon from ancient Chinese mythology and is activated by the corresponding button;
  • The “black dragon” bet is a bet on the numbers 2, 6, 8, 10, 13, 17, 20, 24, 26, 28, 29, 31, 35. It looks like a dragon from ancient Chinese mythology and is activated by the corresponding button;
  • Splits – bet on all adjacent cells of the same color on the table. There are red and black splits. Numbers 9 and 12, 16 and 19, 18 and 21, 27 and 30 participate in the red split;
  • Numbers 8, 11, 10, 13, 17, 20, 26, 29, 28, 31 are involved in the black splits. Moreover, pairs are formed as follows: 8 and 11, 10 and 11, 10 and 13, 17 and 20, 26 and 29, 28 and 29, 28 and 31.

Spingo Roulette

An interesting variation of European roulette from MicroGaming. Its most unusual component is that one of the balls located there is randomly fired from the pipe in the center of the rotating wheel, after which it falls into one of the sectors.

This is how numbered balls appear in many lotteries, stirred in a closed space by a jet of air and randomly pushed through a pipe to the surface. In Spingo, the balls are also numbered from 1 to 10, and there are two sets of such balls. And there is only one ball with number 0. Thus, 21 balls are involved in the roulette. After the drop, the ball returns to the rest of the balls. The spinning wheel is divided into 25 color sectors, of which 24 are equally divided into red, yellow and blue sectors. And only one sector is green, which acts as an analogue of zero in standard roulette.

Spingo Roulette

The gaming table differs from the standard one, but not much. On it, you can bet on the drop of a ball with a certain number on a sector with a certain color; to hit a ball with a certain number in the red, yellow or blue sector; on an even or odd ball number; for number intervals; on the color of the sector where the ball will stop; on the drop of a ball with number 0; to hit the ball in the green sector. These rates can be combined.

As usual, the player makes initial bets. There are restrictions on the minimum and maximum bid for positions. Payments are made according to the following bets that have played (in brackets the coefficient is indicated):

  • on number and color (32:1);
  • to the green sector (24:1);
  • to number 0 (20:1);
  • to a number except 0 (10:1);
  • on a color other than green (3:1);
  • to numbers from 1 to 5 (2:1);
  • to numbers from 6 to 10 (2:1);
  • to even/odd numbers (2:1);

Roulette Bull (La Boule)

Roulette Bull appeared several centuries ago and is still in demand by casino players. Technically, a variation of this roulette, which is also called “round roulette” in some online casinos, has a significant difference from its predecessors in reality – it does not have the spinning wheel we are used to. Instead, there is a recess in the form of a wide bowl, in which there are 36 small cells-recesses, in which numbers from 1 to 9 are scattered.

Roulette Bull

Unlike classic roulette, the numbers here are arranged in order on the first and second ring of numbers: 1, 2, …, 9, 1, 2, …, 9. It turns out that each number is presented four times on the roulette wheel. And the ball itself is launched by the usual movement in a circle counterclockwise.

Another important difference between Boule roulette and other types of roulette is that in addition to black and red cells (cells 1, 3, 6, 8 are black; cells 2, 4, 7, 9 are red) there are also four yellow ones. In these yellow cells are “fives”, which perform the function of “zero”.

According to the rules of Bull Roulette, you can make the usual bets on specific numbers, as well as on “red-black” and “even-odd”. There are also bets on groups of numbers, in Boole roulette these are small numbers (from 1 to 4) and large numbers (from 6 to 9). Please note that in all bets (except for a bet on a specific number), “fives” do not participate. This is where the very percentage of casino winnings lies. Only a specific bet can be placed on the “five”. Moreover, in the case of a winning bet on the “five”, some casinos take a certain percentage of the winnings. Considering that there are four “fives”, the casino with a probability of 1 to 9 will not pay out the winnings in full. And it is also possible that the online casino will withhold a commission from each win in this game.

  • to a specific number, including number 5 (8:1);
  • on 2 adjacent cards (25:1);
  • to less (1-4) or more (6-9) (2:1);
  • to even or odd, except for number 5 (2:1);
  • on red or black, except for number 5 (2:1);

Mini Roulette

Mini Roulette

Mini Roulette is a variation of European Roulette that was invented by the well-known gambling company Playtech. The main difference between mini roulette and its progenitor is that the playing field, like the roulette wheel itself, contains only 12 numbers, including zero. Bets in mini roulette can be made as usual (on a number from 0 to 12, “even-odd”, “red-black”), as well as on combinations of numbers that differ from European roulette. Here are some of them: from 1 to 6, from 4 to 9 and from 7 to 12. You can also bet on rows with numbers: 3, 6, 9, 12 or 2, 5, 8, 11 or 1, 4, 7, 10.

Over time, mini-roulettes with “double zero” appeared, i.e. they were a simplified prototype of American roulette. But still, statistically, the probability of winning in mini-roulette is higher than in other games, and the limited number of bets simplifies the game. It is these facts that have made mini-roulette quite popular among gambling. Moreover, you can now play it not only in online casinos, but in real gambling establishments. This type of roulette is especially popular among beginners, since roulette itself does not belong to simple gambling. And in mini-roulette there are few rules, and the game proceeds faster. Although mini roulette has its drawbacks, because the percentage of bets in it is less than in the classic types of roulette.

3D or HD roulette

3D or HD roulette

This type of roulette is nothing but another virtual invention in which the graphics are provided at the highest level and the game process is as realistic as possible. This roulette was designed solely for the convenience of players, as a result of which it has confidently gained a foothold in online casinos. Of course, from the point of view of the game, the quality of the image does not affect the roulette algorithm in any way. It is simply more pleasant for the player to watch a high-quality image and nothing more.
