the tokens representing armies that don't 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. Strategy Basic strategy The official rulebook recommends three basic strategy points for play under the standard rules: Players should control entire continents to get the bonus reinforcement armies. Players should watch their borders for buildups of armies that could imply an upcoming attack. 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). 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 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
