Risk (game)#Computer implementations and video games

Risk was invented by French film director Albert Lamorisse and originally released in 1957 as La Conquête du Monde (The Conquest of the World) in France.{{cite web |last1=Veronese |first1=Keith |title=The Origins and Evolution of the Strategy Board Game RISK |url=https://gizmodo.com/the-origins-and-evolution-of-the-strategy-board-game-ri-5897532 |website=Gizmodo |access-date=4 March 2024 |language=en |date=30 March 2012 |archive-date=4 March 2024 |archive-url=https://web.archive.org/web/20240304195605/https://gizmodo.com/the-origins-and-evolution-of-the-strategy-board-game-ri-5897532 |url-status=live }} It was bought by Parker Brothers and released in 1959 with some modifications to the rules as Risk: The Continental Game, then as Risk: The Game of Global Domination.{{cite book |url=https://archive.org/details/riskadversariesa0000axel |url-access=registration |title=Risk: Adversaries and Allies: Mastering Strategic Relationships |author= Alan Axelrod |author-link= Alan Axelrod |publisher=Sterling |year= 2009 |isbn=978-1402754111 }}

The first new version of Risk was released in 1986. Called Castle Risk, it featured a map depicting 18th-century European castles instead of a map of the world, and it was a financial disappointment. In 1993, the rules for Secret Mission Risk, which had been the standard in Europe, were added to the United States edition. After a limited special-edition release in 1999, in France, called Risk: Édition Napoléon in commemoration of 200th anniversary of the Napoleonic era (1799–1815), a new edition called Risk: 2210 A.D. was published in 2001 by Hasbro's Avalon Hill division. The game was futuristic-themed, featuring moon territories, ocean territories and commander units and offered a number of expansions. Starting in 2002, Risk versions themed around media franchises such as The Lord of the Rings, Star Wars, and Transformers were released, sometimes with as many as six editions per year. A collector's edition of classic Risk in a bookshelf-format wooden box was issued in 2005 as part of the Parker Brothers Vintage Game series, distributed through Target Stores. In 2008, Winning Moves, a Hasbro licensee, introduced 1959 Risk, a reproduction of the original Parker Brothers version with original artwork, wooden playing pieces and rules. Many themed versions are currently being published, and new themes continue to be introduced.

In the first editions, the playing pieces were wooden cubes (one set each of black, blue, green, pink, red and yellow) representing one troop each and a few rounded triangular prisms representing ten troops each, but in later versions of the game these pieces were molded of plastic to reduce costs. In the 1980s, these were changed to pieces shaped into the Roman numerals I, III, V, and X. The 1993 edition introduced plastic infantry tokens (representing a single unit), cavalry (representing five units), and artillery (representing ten units). The 40th Anniversary Collector's Edition contained the same troop pieces but made of metal rather than plastic. In the 2005 "bookcase" edition, playing pieces are once again wooden cubes.

File:Risk (game) territory cards.jpg

Equipment includes a large tabletop board depicting a political map of the world, divided into forty-two territories, which are grouped into six continents by color. In addition to shared boundaries between territories which define routes of attack/defense, numerous special trans-oceanic or trans-sea routes are also marked; for example, the route between North Africa and Brazil. The oceans and seas are not part of the playing field.

Each Risk game comes with a number of sets (either 5 or 6) of different colored tokens denoting troops. A few different or larger tokens represent multiple (usually 5 or 10) troops. These token types are purely a convention for ease of representing a specific army size. If a player runs out of army pieces during the game, pieces of another color or other symbolic tokens (coins, pieces from other games, etc.) may be substituted to help keep track of armies.

Also included is a deck of Risk cards, comprising forty-two territory cards, two wild cards, and twelve or twenty-eight mission cards. The territory cards correspond to the 42 territories on the playing board. Each of the territory cards also depicts a symbol of an infantry, cavalry, or artillery piece. One of these cards is awarded to a player at the end of each turn if the player has successfully conquered at least one territory during that turn. No more than one card may be awarded per turn. If a player collects either three cards with the same symbol, or one of each, or any two plus a wild card, they may be traded in for reinforcements at the beginning of a player's turn. These cards can also be used for game set-up. The two wild cards depict infantry, cavalry and artillery pieces. Because these cards have all three symbols, they can match with any two other cards to form a set. The mission cards each specifying some secret mission (something less than 'conquer the world') are used in the Secret Mission Risk rule variant.

Standard equipment also includes five or six dice in two colors: three red dice for the attacker, and two or three white or blue dice for the defender. There is also a Golden Cavalry piece used to mark the progressive turn-in value of matched sets of territory cards.

In 2022, the iconic Risk logo undertook a rebranding conducted by Toronto-based creative and design agency Quake.{{Cite web |first=Justin |last=Crann |date=2022-09-02 |title=How Hasbro reimagined two iconic board game logos |url=https://strategyonline.ca/2022/09/02/how-hasbro-reimagined-two-iconic-board-game-logos/ |access-date=2022-09-13 |website=strategy}}

The following is a typical layout of the Risk game board, with a table of the corresponding continent and territory names.{{cite web |url=http://www.gamingcorner.nl/risk-territories.htm |title=Risk territories |work=The Gaming Corner |access-date=2006-05-12 |df=dmy-all |archive-date=14 April 2012 |archive-url=https://web.archive.org/web/20120414205101/http://www.gamingcorner.nl/risk-territories.htm |url-status=live }} Each territory on the typical Risk game board represents a real-life geographical or political region. 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. Most of the territories represent a combination of countries or states; some that have names of single countries or states, such as Argentina, do not represent the boundaries of the real-life entity. Antarctica, the Caribbean, New Zealand, and the Philippines are not represented.

The numbers in parentheses represent the number of additional armies granted during the reinforcement stage of a player's turn who controls all of the territories in that continent. Some versions of the board use alternative names for some territories. These names are in parentheses. Not all variations occur concurrently.

The territory of Afghanistan does not include the present-day country of Afghanistan.

In the 40th Anniversary Collector's Edition, the movement route between the territories of East Africa and Middle East was removed; this was later confirmed to be a manufacturing error, an error repeated in Risk II. Subsequent editions restored the missing route.

Setup consists of determining order of play, issuing armies to players, and allocating the territories on the board among players, who place one or more armies on each one they own. At the beginning of a player's turn, they receive reinforcement armies proportional to the number of territories held, bonus armies for holding whole continents, and additional armies for turning in matched sets of territory cards obtained by conquering new territories. The player may then attack, move their armies, or pass.

On a player's turn, after they have placed their reinforcements, they may choose to attack territories adjacent to theirs which are occupied by enemy armies. A territory is adjacent if it is connected visibly by land, or by a "sea-lane". Attacks are decided by dice rolls, with the attacker or defender losing a specified number of armies per roll. When attacking, a battle may continue until the attacker decides to stop attacking, the attacker has no more armies with which to attack, or the defender has lost their last army at the defending territory, at which point the attacker takes over the territory by moving armies onto it and draws a territory card for that turn.

At the end of a player's turn, they may move armies from one of their territories to another "connected" territory. A player is eliminated from the game when they have lost their last territory. The player that defeated them receive the defeated player's territory cards, if any. The victor is the last player remaining when all other players have been eliminated. There are special rules for two-player games: the territories are divided between the two players and a neutral army during setup. In play, the neutral army only plays defense when attacked, never attacks or moves armies, and does not have a turn like an active player. If the neutral army is eliminated, the game continues under normal rules.

Some editions have rules variants regarding how armies or territories are allocated during setup or how armies may be moved at the end of a turn. There are also variations in the tokens representing armies that do not affect play. European editions assign each player a secret mission, and the game goes until one player completes their mission rather than conquers the world. Different editions have differing numbers of such missions. The Italian edition uses a different number of dice in battle. Themed variants have different map configurations and substantially different rules.

The rules of some editions describe a variant called Capital Risk, where each player has a capital in one of the initially occupied territories. The player to capture all capitals wins. Any armies and territories that belong to the losing nation are turned over to the victor. Capital Risk often leads to much shorter games. Other rules variants for "Risk experts" are also listed. Gaming clubs may also have "house rules" or competition-adjusted rules.{{cite web |title=rules of Risk - Hasbro Toy |url=https://www.hasbro.com/common/instruct/risk.pdf |website=Hasbro.com |publisher=Hasbro |archive-url=https://web.archive.org/web/20030913141700/https://www.hasbro.com/common/instruct/risk.pdf |archive-date=13 September 2003 |url-status=live }}

The official rulebook recommends three basic strategy points for play under the standard rules:

1. Players should control entire continents to get the bonus reinforcement armies.
2. Players should watch their borders for buildups of armies that could imply an upcoming attack.
3. Players should build up armies on their own borders for better defense.

Holding continents is the most common way to increase reinforcements. Players often attempt to gain control of Australia early in the game, since Australia is the only continent that can be successfully defended by heavily fortifying one country (either Siam or Indonesia).{{cite web |title=Risk – Strategy |url=http://www.hasbro.com/risk/default.cfm?page=strategy |work=Hasbro.com |access-date=2007-03-12 |url-status=dead |archive-url=https://web.archive.org/web/20070219173015/https://www.hasbro.com/risk/default.cfm?page=strategy |archive-date=2007-02-19 |df=dmy-all}} Generally, continents with fewer access routes are easier to defend as they possess fewer territories that can be attacked by other players. South America has 2 access points, North America and Africa each have 3, Europe has 4, and Asia has 5.

Generally, it is thought advisable to hold Risk cards until they can be turned in for maximum reinforcements. This is especially true earlier on in gameplay, because extra armies make a greater difference in the beginning of the game. Eliminating a weak player who holds a large number of Risk cards is also a good strategy, since players who eliminate their opponents get possession of their opponents' Risk cards. In this case, trading in Risk cards earlier may help acquire the necessary troops. If the conquering player has six{{cite web |url=http://www.hasbro.com/common/instruct/risk.pdf |title=Risk: The World Conquest Game |work=Hasbro |access-date=2015-05-24 |page=10 |archive-url=https://web.archive.org/web/20190901093030/https://www.hasbro.com/common/instruct/risk.pdf |archive-date=September 1, 2019 |url-status=live}} or more Risk cards after taking the cards of another player, the cards must be immediately turned in for reinforcements until the player has fewer than five cards and then may continue attacking.

"Turtling" is a defensive strategy where a player who feels vulnerable tries to become too expensive to be removed while remaining a threat to harass other players. The objective of this strategy is to avoid early defeat. 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". The term was popularised in real-time strategy games where a player creates a defensive perimeter or a turtle shell around the base of operations. Solutions to counteract this strategy using cooperation have been proposed.{{cite book |first=Ehsan |last=Honary |year=2007 |url=http://www.totaldiplomacy.com |title=Total Diplomacy: The Art of Winning Risk |publisher=Total Diplomacy |isbn=978-1-4196-6193-8 |access-date=2009-12-12 |url-status=dead |archive-url=https://web.archive.org/web/20091124142100/http://www.totaldiplomacy.com/ |archive-date=November 24, 2009 |df=dmy-all}}

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, they are often broken. Alliance making/breaking can be one of the most important elements of the game, and it adds human interaction to a decidedly probabilistic game. Some players allow trading of Risk cards, but only during their turn. This optional rule can make alliances more powerful.

Capturing a territory depends on the number of attacking and defending armies and the associated probabilities. In a battle to completion, a player who has more armies (even just one more) has a significant advantage, whether on attack or defense (the number of attacking armies does not include the minimum one army that must be left behind in the territory).

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. 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 they may choose to roll fewer than three. Thus when rolling three dice against two, three against one, or two against one, the attacker has a slight advantage, otherwise the defender has an advantage.

There are online tools available to compute the outcome of whole campaigns (i.e. the attacking of several territories in a row).{{cite web|url=http://armsrace.plynd.com/probabilities|title=Risk campaign probabilities|access-date=2015-01-13|archive-url=https://web.archive.org/web/20150208181409/http://armsrace.plynd.com/probabilities|archive-date=2015-02-08|url-status=dead}}

RisiKo! is a variant of the game released in Italy, in which the defender is allowed to roll up to three dice to defend. This variation dramatically shifts the balance of power towards defense.

Many of the official versions of Risk listed above have their own rules which may differ slightly or even significantly from the original game of Risk.

• Risk Legacy. There are five factions, each with different pieces and rules. This game is the actual originator of the term Legacy game,{{cite web | url = https://www.polygon.com/2016/8/24/12617898/seafall-review-preview-unboxing-pandemic-legacy-rob-daviau | title = SeaFall, the spiritual successor to Pandemic Legacy, is a handful | work = Polygon | date = August 24, 2016 | accessdate = February 3, 2018 | first = Charlie | last = Hall | archive-date = 8 November 2020 | archive-url = https://web.archive.org/web/20201108111831/http://www.polygon.com/2016/8/24/12617898/seafall-review-preview-unboxing-pandemic-legacy-rob-daviau | url-status = live }} which means that rules/mechanics are added and changed, previous games permanently affect all future games, and cards are permanently modified and destroyed.

• Risk Europe differs markedly from the original game, in that each territory generates a specific income for the player, and the player can purchase new units based on the amount of revenue received. Also, each unit succeeds in its attack if the player hits a specific number or lower during the attack. Also, a new type of unit known as siege weapons is provided to players. Also, players have different types of units, each with their own types of tactics and attacks. All of these game mechanics are notably similar to the basic game-play format of Axis and Allies.[https://www.ultraboardgames.com/risk/europe-game-rules.php Risk Europe Game Rules], ultraboardgames website, accessed April 6, 2021.[https://bsgames.ca/family-game-review-risk-europe/ Family Game Review: Risk Europe] {{Webarchive|url=https://web.archive.org/web/20210228025704/https://bsgames.ca/family-game-review-risk-europe/ |date=28 February 2021 }}, https://bsgames.ca/family-game-review-risk-europe/ , accessed April 6, 2021.[https://brilliantmaps.com/risk/ 27 Best Risk Board Game Versions Based On Real Player Reviews] {{Webarchive|url=https://web.archive.org/web/20210404204305/https://brilliantmaps.com/risk/ |date=4 April 2021 }}, August 28, 2016.

• Risk 2210 A.D. has numerous rules which differ from the original game. The board includes water and moon territories. Game units include commanders (land, naval, space, nuclear, diplomat). Players earn and spend "energy" to obtain commanders, cards, and space stations and to activate some command cards. Players can roll an 8-sided die in some instances. Armies are not acquired through card trading. The game is only 5 years (turns) long; the winner is the player with highest score at the end of the last year. Players bid energy to determine turn order rather than following the same order determined by a dice from the beginning of the game.[https://web.archive.org/web/20151219210751/http://avalonhill.wizards.com/games/risk/risk-2210-ad Risk 2210 page], Avalon Hill website.[http://www.gamingcorner.nl/rules/boardgames/risk%202210%20ad_uk.pdf Game manual for Risk 2210 AD]. {{webarchive |url=https://web.archive.org/web/20051026084143/http://www.gamingcorner.nl/rules/boardgames/risk%202210%20ad_uk.pdf |date=October 26, 2005 }}. gamingcorner.nl website, accessed April 7, 2021.

Many variants have been published by other groups or companies, that are based on the original concept of the game of Risk and that contain much of the functionality of the original, but are not licensed by Hasbro, such as the video games Global Domination and Lux. Known as Risk clones, such variants have names not containing the term "Risk" to avoid legal issues.{{Cite thesis|degree=Master of Science |title=A Multi-Agent System for playing the board game Risk |url=https://www.diva-portal.org/smash/get/diva2:831093/FULLTEXT01.pdf |archive-url=https://web.archive.org/web/20220322202329/https://www.diva-portal.org/smash/get/diva2:831093/FULLTEXT01.pdf |archive-date=2022-03-22 |url-status=live |author=Fredrik Olsson |date=March 2005 |publisher=Blekinge Institute of Technology |access-date=2022-03-22}}{{cbignore|bot=medic}} Some of these clones are available commercially, of which many have been released through the iTunes App Store, especially for the iPad.{{cite magazine |author=Ryan Rigney

NarcoGuerra is a newsgame based on the basic Risk rules, played out over a map of Mexico with the intent of educating people on the Mexican Drug War. An example of a board game inspired by Risk is the Argentine TEG.

In addition to Risk clones, third-party products have been created which slightly modify traditional gameplay. Among the most popular third-party editions are virtual dice-rolling simulators. These can act as virtual replacements to traditional dice or be used to automatically simulate the results of large battles between territories—significantly speeding up gameplay.

Several video game versions of Risk have been released as Risk, starting with the Commodore 64 edition in 1988{{cite web|url=http://www.islandnet.com/~kpolsson/c64hist/c641988jun.htm |work=Chronology of the Commodore 64 Computer |access-date=2007-05-12 |title=June–December 1988 |date=July 29, 2009 |first=Ken |last=Polsson |url-status=dead |archive-url=https://web.archive.org/web/20080709011042/https://www.islandnet.com/~kpolsson/c64hist/c641988jun.htm |archive-date=July 9, 2008 }} and the Macintosh edition in 1989. Various other editions have been released for PC, Amiga, Sega Genesis, PlayStation, PlayStation 2, Game Boy Advance, and Nintendo Switch. In 1996 Hasbro Interactive released a PC version of Risk that included a new variation on the game called Ultimate Risk, which did not use dice but rather implemented the use of forts, generals, and complex battle strategies. Risk II for PC and Mac was released as a 2000 video game which includes classic Risk as well as board and gameplay variations. In 2010, Pogo.com added a licensed version of Risk to its library of online games. An Xbox Live Arcade version of Risk called Risk: Factions was released on June 23, 2010. It includes classic Risk as well as a factions mode where players can play as Zombies, Robots, Cats, Soldiers, or Yetis.
