Risk

A typical game of Risk in play. 

Many game elements such as the board, dice, units and cards are visibleRisk is a commercial turn-based strategy board game produced by Parker Brothers, a division of Hasbro. It was invented in the early 1950s by the French movie director Albert Lamorisse. Risk shares many characteristics with wargames, yet relative to other war games, it is simple and abstract. It makes little attempt to accurately simulate military strategy, the size of the world, the logistics of long campaigns or real-world luck.

Overview and most common rules

Risk is a turn-based game for two to six players. It is played on a board depicting a stylized political map of the world, divided into 42 territories, which are grouped into six continents. To start, each player rolls one die. The player who rolls the highest number plays first and the sequence goes clockwise. Each player in turn places an army on a territory to claim it until all territories have been claimed; following this, the players position among their territories the armies remaining from their starting number of armies (varying depending on the number of people playing; for six, each gets 25; for five, 30; four, 35; etc.).

The game is played by allocating armies to the territories that you control, and then attacking neighboring territories in order to conquer them. The outcome of battles is decided by rolling dice. The attacking player selects up to three armies from his/her territory to participate in the attack, with the caveat that at least one army must be left behind. The attacker rolls one die, usually red, for each attacking army. The defending player may select up to two armies to participate in the defense of the territory (including their last army), and rolls that number of dice, usually white. The attacker's highest roll is then compared to the defender's highest roll. The player with the higher of the two is deemed successful, and the opposing player must remove one army from the territory. If both highest rolls are equal, the defender is deemed successful, and the attacker must remove one army. The process is then repeated with each player's second highest roll. If the attacker is using more dice than the defender, the remaining dice are ignored. If an attacker succeeds in removing the last defending army, s/he moves any attacking armies into the conquered territory.

Players may reinforce their armies at the beginning of their turn in two ways. First, a player receives additional armies each turn based on the territories in their control. The player will receive one army for each three territories under their control, with a minimum of three per turn. Additional armies are given for controlling all territories in a continent or continents (see table below). Second, players collect cards, drawing one card from the deck on any turn during which they captured a territory. At the start of their turn, a player may turn in a set of three identical cards, or a set of one card of each of the three types, for additional armies. The number of armies awarded increases as sets of cards are turned in. At the end of each player's turn, they may move any number of armies from one (and only one) territory they control into one (and only one) neighboring territory they already occupy, again always leaving at least one army in each territory.

While it is possible to win by controlling all of the territories on the board (in so doing eliminating all other players), this results in a very long game with a drawn out and predictable end. Some versions of the rules specify a lower winning target (typically thirty-five territories), or allocate a random, secret, "mission" to each player at the beginning of the game. Possible missions include gaining control of all territories in two or three specified continents, or eliminating another specified player; the first player to achieve their mission wins the game.

Since playing Risk with fewer than three players is not always as engaging as games with more players, some versions of the rules recommend having some territories occupied by neutral armies to come close to the strategic value and fun of an actual three-way game.


Rules and differences
Risk was designed by Albert Lamorisse (a French filmmaker) and released in France in 1957. From the pre-1959 version, Parker Brothers and Hasbro have included many different rules for the game. There are many computer and Internet versions which have different rules, and hundreds of Risk clubs which also have their own "house rules" or competition-adjusted rules. It would be unwieldy to include here all the different sets of rules, or to list every rule or goal that differs from place to place or version to version.


Strategy for standard rules
Continent # of Extra armies 
Africa 3 
Australia 2 
Asia 7 
Europe 5 
North America 5 
South America 2 

The strategy of Risk is to have the largest number of armies in the place where they will do the most good. One of the easiest ways to gain armies is to hold continents. If you hold an entire continent for an entire turn, you receive a number of extra armies, which is dependent upon the continent (see the table to the right).

A common strategy is to secure Australia or South America early in the game and sit back and build up armies, letting the other players kill each other off. Then, when the others are at the weakest, strike. If more than one player attempts to follow this strategy it can lead to an internecine bloodbath. However this strategy will often backfire if the game develops into a stalemate, where all the players build up in larger continents waiting for someone to make a move. The controllers of the larger continents will receive considerably more men than the controllers of the smaller continents. Also if a player uses this strategy and another player gains control of the larger continent above them, they will be his or her next target, because they receive fewer men each turn, and are therefore usually an easy target for invasion.

Another rule of thumb players follow is to never take Asia early in the game; it is the largest continent and the least defensible, and trying to hold it leaves the player open on too many fronts. If a player does attempt to take Asia, they must hold Ukraine, because they have to guard from invasion in 3 different border territories (Ural, Afghanistan, Middle East). However Ukraine only has to have enough forces to invade one of these territories to stifle the player's income of men for that turn.

A good rule is to always take at least one territory per turn, even if you expect to lose it the next. By taking a territory, you gain a Risk card. Combinations of 3 Risk cards can be played in future turns in exchange for more armies (this being a "reward" of sorts for aggression). A sudden influx of armies at the beginning of a turn can change everything. Every turn a player successfully gains another territory, he or she also gains one-third of a new set. For example, if the next set of cards will grant a player 30 armies, then the card earned is essentially worth 10 armies.

After winning a battle, it is tempting to leave a single, occupying army in a territory and push all others into the newly defeated territory. This leads a strong front line with no reserves. If an opponent breaks the leading edge of your advance, he or she can often run deep into your rear area as they only have to defeat a single army in each territory. Leaving two or three armies in each territory will slow your advance, but it minimizes the damage if an opponent breaks through.

Sadly, once a player has become dominant in a particular session, the endgame becomes more or less inevitable. Risk is a game of numbers, and, consequently, the game can "tip" very hard in a player's favor once he or she controls enough territories and continents to build up a steady stream of reinforcements each turn. When this happens, there is very little that can be done strategically to stop them.

Because cards in the standard rules quickly build to high value, some players, in games of 5 or 6 people, manage to play a very effective game by mostly ignoring continents, focusing instead on wiping other players out and seizing their cards. If two or three weaker players with 3 or 4 cards each can be defeated in the space of a few turns, without hopelessly weakening the attacker in the process, he can often win the game, even against strong-entrenched remaining opponents.


Politics and alliances
Whenever there are more than two players remaining in the game, alliances will be an important — perhaps the most important — part of Risk strategy. There are no rules restricting the formation or break-up of alliances. A good Risk player will use diplomacy to arrange alliances to take down stronger opponents and will similarly attempt to use diplomacy to avoid alliances being made against him/herself.

The importance of this should not be underestimated. This "meta-game" is perhaps the single most important factor determining the outcome of Risk games amongst players who have already grasped basic Risk tactics and strategy.
