Dice- a popular source of randomness in board games (especially in the game of the same name). Among role players, the name "dice" is also common. dice).

The dice is usually made in the form of a six-sided die with numbers from 1 to 6 applied to its sides, and the sum of the numbers on opposite faces should be equal to seven. A dice can be viewed as a random number generator in an integer interval with the same probability of all numbers in the interval falling out. Such generators are denoted by 1dN. So, for example, a regular six-sided die is 1d6; tossing a coin is the work of the 1d2 generator, and so on.

The abbreviation MdN stands for the sum of M applications of 1dN. It should be noted that MdN gives integers in the interval . The probability of a number falling out of this interval grows as you approach its middle (see binomial distribution).

So, for example, using a d4 die and rolling it twice, we get a 2d4 generator giving the following options:

An example of a generator that does not fall under the definition of MdN: a deck of cards into which no drawn cards are returned. It will be 1dN only for the first attempt, the distributions of subsequent attempts will depend on the previous results.

A set of dice for D&D games. The last two are "percentage dice" d100 for units and tens

Role-playing games (such as those based on the Dungeons & Dragons rules) use dice with 4 (tetrahedron), 6 (cube), 8 (octahedron), 12 (dodecahedron), 20 (icosahedron) and other number of faces. Lowe Zocchi invented the zochchihedron, a 100-sided dice. However, to obtain a number from 1 to 100, two 10-sided dice are more often used.

In the roleplaying environment, the type of die is often denoted by the letter "d" ( d ices) or "to", ( to awns) after which the number of sides is indicated. In addition to the six-sided dice (d6) familiar to many, four- (d4), eight- (d8), ten- (d10), twelve- (d12) and twenty-sided (d20) dice are used. The designation d100, d% or "percentage cube" is also used, which is two decahedrons, one of which is used to determine the number of tens, and the second - units.

Story

The exact date of the appearance of the dice is unknown. However, it has been established that the backgammon game, where such ancient random number generators should have been used, is more than 5 thousand years old.

In the 11th century, astragalomancy developed in Byzantium - the art of predicting the future by dice.

A dice (in English "dice", derived from the Old French dé, and also from the Latin datum, meaning "given; what is given or played") is a small object that, when dropped on a flat surface, occupies one of several possible stable provisions. Dice are used as a means of generating random numbers in gambling. They are also widely used in board and role-playing games.

The traditional dice is a dice with six sides marked with numbers from 1 to 6. The purpose of the dice is to show a randomly determined integer from one to six, each of which is equally probable due to the correct geometric shape. There are a huge number of varieties of dice: in shape - dice can be polyhedral or irregular in shape, in terms of information content - symbols instead of numbers can be applied to their faces. Differences like these allow dice to be used to produce results that differ from the classic 1-2-3-4-5-6 pattern. There are also dice that are weighted on one side or with other changes that are invisible to the eye, designed to rig the results. The purpose of such dice is to deceive other players for the sake of winning money or just for fun, such as tricks.

A die is usually made in the form of a cube with numbers from 1 to 6 marked on its sides (they are usually arranged so that the sum of the numbers on diametrically opposite sides is 7). A dice can be considered as a random number generator in an integer interval with almost the same probability of falling out of all numbers in the interval. Such generators are denoted by 1dN.

So, for example, a regular die is 1d6; tossing a coin is the work of the 1d2 generator, and so on.

The abbreviation MdN stands for the sum of M applications of 1dN. It should be noted that MdN gives integers in the interval . The probability of a number falling out of this interval grows as you approach its middle (see binomial distribution).

Other excavations of ancient burials of the Indus civilization point to the South Asian origin of dice. The dice game is referred to as indian game in the Rig Veda, Atharva Veda and in the list of the Buddha's games he will not play. In the Indian epic Mahabharata, Yudhishthira and the Kauravas dice the northern principality of Hastinapura, over which a war begins.

According to Greek tradition, dice were invented by Palamedes in order to entertain bored Greek soldiers awaiting battle near Troy.

Modern dice owe their origin to the ancient game of skill called “grandmothers”, which was played mainly by women and children. Game process consisted in throwing small bones of ungulates, pasterns, from where the name of the game appeared. The four-sided shape of the pastern became the first dice shape in history, and the material used to make it gave the name we still use today - "bone". Modern Mongols still use such tetrahedral “step” dice for games and predictions. In addition to the classical bones of domestic animals, materials such as ivory, wood and plastic - cellulose acetate - are used to make modern dice. In historical annals, dice and money games are often confused, but each of them has gone its own way from ancient times and is still popular today.

gambling with two or three bones were a very popular form of entertainment in Greece, especially in the upper strata of society. They were constantly played during feasts.

In the Middle Ages, dice was a favorite pastime of knights; there were schools of the game and guilds of players. After the fall of feudalism, the Landsknechts gained a reputation as the most scandalous dice players of the day; the cubes were decorated with skillful carvings depicting people and animals. In France, both knights and ladies played dice, despite new and new laws, including the prohibitions of St. Louis in 1254 and 1256.

Marking on Chinese dominoes originated from the marking of cubes.

Device

Standard dice are small dice, most commonly 1.6 cm across, whose faces are numbered from one to six, usually with round dots called points. Traditionally, the opposite sides of the cube add up to seven, with faces 1, 2, and 3 having a common vertex, these faces can be located clockwise or counterclockwise with respect to the vertex. If faces 1, 2 and 3 go counterclockwise, the die is called right and vice versa. Western dice are usually right handed while Chinese dice are left handed.

The points on the dice are arranged in a special order, as shown in the figure on the right. On Asian dice, the scoring order is similar to European, but the scoring is closer to the center of the face; one point is larger than the others, and four points are colored red. In some of the old sets, one point was indicated by an indentation without staining. The black edge "one" and the combination of black and white flowers on the verge of "four" was considered unlucky, so red, the color of luck in Chinese culture, was supposed to neutralize this sign. The word for four (四 si) in Chinese sounds like the word for death (死 si) and is considered unlucky. It is likely that the red "fours" are of Indian origin.

The result of throwing a dice is considered random, since there are such uncertain factors in this process as the movement of the thrower's hand and the position of the die before the throw. Thus, the dice can be considered the prototype of the random number generator. Some people believe that dice-styled glasses cause a slight bias, but no research has been done to support this idea. By the way, this may be true for Asian dice with an enlarged image of one point. Casino dice are produced with filled markings, which confirms the even distribution of random numbers.

Every self-respecting table maker must collect dice. Cubes are chosen very carefully, they are carefully stored and they firmly believe that they bring good luck if they are chosen correctly.

In this article we will talk about the variety of cubes. Perhaps these are the dice you dreamed of adding to your collection, but you never knew about their existence.

Traditional dice.

The oldest and simplest type of dice is considered to be six-sided dice. They can be used in all traditional games; starting with backgammon and ending with monopoly. All of us in childhood played various board games using six-sided dice. Often they were made of inexpensive plastic and painted in bright colors.

Round game dice.

Pretty interesting variation. hex dice which looks like a ball. Thanks to the deftly placed pellets inside, the cube rolls freely, but the ball stops with only one face.

Role playing dice.

Everyone knows the desktop role-playing game Dungeons & Dragons, which glorified a set of seven dice with the numbers 4, 6, 8, 10, 12, 20. In a set of ten-sided dice, there are two dice that can be thrown at the same time and you can end up with the number 1-100.

Hundred-sided gaming dice.

In the above game, there is such a remarkable difference as replacing 2 ten-sided dice with one 100-grain. This kind of cube is characterized by a spherical shape, which allows it to roll freely. The 100-sided game dice are usually made large and heavy to make it easier to count the resulting number without the help of points.

Five-sided dice.

The exact science of mathematics has established that a triangular prism with its faces (to be specific, 5 faces) has an equal chance of falling out when thrown. The type of dice not used in any board game, since the cube was created to glorify mathematics as a science.

Calendar dice.

You can have a lot of fun with your friends if you change the dice for a dice from the calendar. The latter are used to show dates and months. It will be fun to watch the reaction of the players who did not notice the substitution when the numbers 2,9,8,7 come up on a six-sided game die at the moment of a roll.

Cubes with a displaced center of gravity.

Designed for fraud. Inside the die is a metal pellet, thanks to which the number 6 falls out much more often than other numbers. Unfortunately, by appearance it is impossible to distinguish such cubes from standard dice.

One-sided dice.

They are also called gembets. They always fall on the table with one face at the moment of the throw. This is another creation of the geniuses of mathematicians. Alas, just as complicated and just as useless.

Mathematical grave bones.

This time, professional mathematicians have created dice that can be used in practice. However, if you have difficulties in mathematics, then they are not for you. Since not every person will guess that the dropped combination “cube root of 64-3” means an elementary unit.

Inserted dice.

Several smaller ones were placed in one transparent large cube. Application of such type of dice It is very convenient when, according to the rules of the game, it is necessary to throw several dice at once. In addition, the use of this type of cube will look quite impressive.

Glowing game cubes.

This kind of dice is very useful for players who suddenly lost their light, because using luminous dice can easily and simply end the game. They are indispensable for children, because at night you can freely play with them under the covers.

Cubes - the history of the game.

A very ancient gambling game in the history of mankind.

Dice-like objects existed in many civilizations. Such a spacious geography of dice is associated with the belief that the dice were sent by the gods so that people would not bother them over trifles. AT Ancient Rome it was believed that at the time of the throw, Fortune, the goddess of luck, helped the person.

Helped to resolve military conflicts. They even determined a new ruler with their help. In medicine, thanks to the bones, they predicted the future. A wide variety of items replaced the ancestors of modern six-sided dice. For example, shamans used fruit bones, seashells, and even sheep horns, teeth, and bones in their rituals. lovers board games in ancient India, instead of a dice, a 4-sided cone was thrown.

The desire to deceive your opponent originated simultaneously with the use of dice in gambling. The proof is the fact that bones with a displaced center of gravity were found during the excavations of Pompeii. Their use guaranteed the player a great chance of getting the desired combination. An active fight against scammers was carried out in medieval Europe. Then they created the Guild of Bone Makers. Its mission was to keep track of irregular or heavy game dice.

Dice were made from a variety of materials - amber, marble, bronze, alabaster, rock crystal and agate. A sign of great wealth and good taste was considered to be dice made of porcelain, ivory and silver.

The advantage of an online dice generator over regular dice is obvious - it will never get lost! The virtual cube will cope with its functions much better than the real one - the manipulation of the results is completely excluded and you can only hope for His Majesty the case. Online dice is, among other things, great entertainment in your spare time. The generation of the result takes about three seconds, warming up the excitement and interest of the players.

A dice (in English "dice", derived from the Old French dé, and also from the Latin datum, meaning "given; what is given or played") is a small object that, when dropped on a flat surface, takes one of several possible positions one side up.

The corners of some dice are rounded for a reason: the dice gets a slightly spherical shape, the sliding on the table surface increases, it rolls almost like a ball, and the distribution of the probabilities of falling out of certain numbers becomes uniform.

Dice are thrown one by one or in groups, from the hand or from a device designed for this purpose, onto a flat surface. On the face of the die, which will be the top after it stops, you can see the value of the roll. A typical dice game today is craps, in which two dice are rolled at the same time and bets are placed on the sum of the points of the two dice. Dice are often used to determine the number of moves on the board. A similar method for determining the distance traveled by a player's chips by playing field used in the popular board game Monopoly.

For board games, computer-generated dice roll results can be used. The values ​​are usually determined using a pseudo-random number generator and then displayed on the screen as some sort of facet of a die. The opposite is also possible, when dice rolls provide the generation of random numbers for computers.
