World Conquest is played by one human player against two to five computer players. There are 42 territories on the screen. Start by selecting which ones you want to own. Your territories are shown in green. When you select a territory, an army is placed there. When you and your opponents have selected all the territories, then you take turns placing your remaining armies in the territories you own.
Start your turn by selecting one you your territories to attack from. Then select a neighboring territory to attack. You can attack overseas where a line indicates a connection. You must have at least two armies on a territory to attack. Chance determines how a battle goes, but chances are weighted by how many armies you have and how many armies the opponent has in that territory. If you do not conquer a territory immediately, you can click on it again to launch another attack.
Once you conquer a territory, some of your armies are automatically moved there. The rest of your armies need to be placed on either the territory you conquered or the territory you were attacking from.
At the beginning of each turn you will receive some new armies to place. The number depends on how many territories you own and how many complete continents you own. (You can place armies 10 at a time by holding down the shift key).
At the end of each turn, you can choose to 'fortify.' This means you can move some armies from one territory to an adjacent territory before the turn is over.
At the end of each turn where you successfully conquered a territory, you get a card. Once you have more than two cards, you may be eligible to turn some in for extra armies. You need to do this at the very start of a turn. There are three suits (soldier, tank and plane). You can turn in a set of cards with all the same suit, or turn in a set of cards representing each suit. There are also wild cards that can be any suit. You get some extra armies to place, plus two extra armies on a territory if that territory is shown on the card and you own it. You must turn in cards if you have more than five.
If you wish to vary the game, you can change the settings of the computer opponents. The ''smart' setting is an opponent that uses strategy to try and win. The 'chaotic' strategy is an opponent that uses force to try and win. The 'grudge' strategy is an opponent that is not so much concerned with winning as it is keeping you out of the game. You can also set the aggressiveness of each opponent.
