A player using this strategy might remain in the game all the way to later stages and then mount an attack on the weakest player and start a chain elimination to remove one player after another to win the game. The player who uses this strategy is called a Turtle. Solutions to counteract this strategy using cooperation have been proposed by Ehsan Template:Not a typo.
The rules of Risk neither endorse nor prohibit alliances or truces. Thus players often form unofficial treaties for various reasons, such as safeguarding themselves from attacks on one border while they concentrate their forces elsewhere, or eliminating a player who has grown too strong.
Because these agreements are not enforceable by the rules, these agreements are often broken. Some players allow trading of Risk cards, but only during their turn.
This optional rule makes alliances more powerful. Defenders always win ties when dice are rolled. This gives the defending player the advantage in "one-on-one" fights, but the attacker's ability to use more dice offsets this advantage, as indicated in the dice probability charts below. Actually capturing a territory depends on the number of attacking and defending armies and the associated probabilities can be expressed analytically using Markov chains , [7] [8] [9] or studied numerically using stochastic simulation.
It is always advantageous to roll the maximum number of dice, unless an attacker wishes to avoid moving men into a 'dead-end' territory, in which case he may choose to roll fewer than three.
The table below states the probabilities of all possible outcomes of one attacker dice roll and one defender dice roll.
Green indicates an advantage to the attacker and red an advantage to the defender. Thus when rolling three dice against two dice the most each player can roll , three against one, or two against one, the attacker has a slight advantage, otherwise the defender has an advantage.
When large armies face off, a player will tend to gain a greater advantage over his opponent by attacking rather than defending. Multiple opponents can change the prudence of such a strategy, however. The following table shows the probabilities that the attacker wins a whole battle between two countries a sequence of dice rolls.
Green indicates an advantage to the attacker i. The number of attacking armies does not include the minimum one army that must be left behind in the territory e. A common situation is that the attacker wants to take over a whole region of countries during the same round, by a series of battles.
After each successful battle, the attacker leaves one army in that country, and continues with the remaining attacking armies into next country. The following table shows the average number of countries that the attacker can take over, as well as the 90 percentile , starting with a certain number of attacking armies in the first battle.
A fixed number of armies is assumed to defend each country. This variation dramatically shifts the balance of power towards defense. As shown in the following table, a defender in this variation has a 1-in-5 chance of holding a country with three defenders against eight armies in a whole battle excluding the one that must remain behind : [12] [13]. For comparison, under the standard rules in which the defender may roll up to only two dice at a time three armies would only have 1-in chance of holding a country against all-out attack by eight.
Over the years, Parker Brothers and Hasbro have published many different editions of rules for the game. This 2-player version is played according to the traditional rules of Risk. Each player takes 40 armies and alternately places one army on an unoccupied territory until each has occupied 14 territories.
The remaining armies are alternately distributed on the occupied territories. The remaining 14 territories are occupied by a force called the Allied Army. These armies are composed of playing pieces different in color from those used by the two players. Two Allied Armies will be placed on each unoccupied territory for a total of 28 armies.
Each player attacks according to the traditional rules. A player may attack the other player or the Allied Army. When a player attacks the Allied Army, the other player rolls the dice for the Allied Army. The game ends when one player loses all his territories. If the Allied Army loses all its territories, game play is continued according to the traditional rules. Each player has a "capitol" in one of the initially-occupied territories.
The player to capture all capitols wins. Any armies and territories that belong to the losing nation are turned over to the victor. Capitol Risk often leads to much shorter games. Secret Mission Risk was the standard game in European editions for some decades [3] and was introduced to US editions in This form of play gives each player a specific mission short of complete world domination. Players do not reveal their missions to each other until the end of the game.
The game ends when the first person to complete his mission reveals his Secret Mission card, thereby winning. Note: In the UK edition, if a player's mission is to destroy all armies of a particular color, and another player kills off the last armies of that color, their mission changes to capturing 24 territories.
In the US edition, no matter who eliminates the last army, the player with the mission wins automatically [15]. In some editions, the cards display either one or two stars. Cards may be exchanged to draft a number of armies depending on the sum of these stars limited from 2 to 10 stars according to the table below. The new armies are immediately deployed in any combination across the player's occupied territories.
If an Objective has been accomplished on the player's turn, that player is prohibited from also drawing a Risk card on that turn. The territory on the card is irrelevant when drafting troops. An additional card exchange regime is to offer a fixed number of armies depending on the emblem on the card. Three infantry would receive four armies, three cavalry would receive six armies, three cannons would receive eight armies, and one of each emblem would receive 10 armies.
Yet another card exchange regime follows the escalating exchange rules, but after awarding 15 armies for the sixth exchanged set the number is reset to the original four armies before increasing again with each exchange. The official rulebook suggests variations to the game-play mechanics for " Risk experts," any or all of which can be used depending on player preference. In addition to these official variations, many computer and Internet versions have different rules, and gaming clubs often use house rules or competition-adjusted rules.
These may include structure such as forts, freeplay players take turns simultaneously , or other rules. There have been other variations of Risk, essentially "house rules," complete with titles like "Ultimate Risk" which is played in the United States.
The following is a typical layout of the Risk game board, with a table of the corresponding continent and territory names. As such, the territory borders are drawn to resemble the geography of those regions.
This provides an interior space on which to place the army units, adds an element of realism to the game, and also adds complexity.
