"Mother 3" is a single-player role playing video game similar to previous games in the "Mother" series. The player controls a party of playable characters who explore the game's two-dimensional fictional world, primarily shown from a top-down perspective. While navigating the overworld, the player may converse with non-player characters, obtain items, or encounter enemies. Winning battles against enemies awards experience points to the party, which is required for leveling up. Leveling up a character permanently enhances its individual attributes such as maximum hit points (HP), power points (PP), offense, and defense. Weapons, armor, or accessories can be equipped on a character to increase certain attributes. The player can restore their characters' HP and PP or heal various status ailments by visiting hot springs which are abundant in the game world, and the player can save the game by talking to frogs. Currency is introduced in the later half of the game as Dragon Points (DP), earned by winning battles and used to purchase items. The player can deposit or withdraw DP from frogs.
