In the Falsebound Kingdom, the player controls an army of Marshals opposed to an army of enemy Marshals. Each warrior commands up to three Duel Monsters. Duel Monsters individually have Attack power and Defense power, and also have HP and AP, the latter representing how many turns they are able to take in battle. Monsters can take items into battle with them with various effects such as increasing their stats or recovery their health. Marshals have an affinity towards certain types of monsters, represented by a colored orb; the closer a monster's orb color is to a Marshal's, the higher that monsters stats will be. Continued service under a Marshal will gradually change a monster's affinity. Monsters can also have unique abilities or attacks with special mechanics, such as hitting multiple targets or doing extra damage to certain enemy types.[2]
Players command their army of Marshals on a field against the enemy Marshals and advance them towards bases held by the other team. When two Marshals come in range of each other, their team of Duel Monsters fights. Whichever Marshal is victorious, they remain in their position on the map while the defeated Marshal is sent to the nearest allied base to slowly recover their strength. At allied bases the player can spend money to upgrade the base with facilities, including speeding up the healing rate of Marshals there or shops to purchase items. The objective is usually to push the player's allied forces to the enemy's central base and capture it.
