===Other modes===
''Mario Party 3'' includes a Duel mode, in which two players use a selection of up to two partners to attack their opponent and deplete their [[Health (gaming)|health]].<ref name="Manual27">''Mario Party 3'' (Nintendo 64) instruction booklet, p. 27</ref> The partners can be positioned in front of or behind the player,<ref name="Manual2829">''Mario Party 3'' (Nintendo 64) instruction booklet, pp. 28−29</ref> and must be paid a salary at the beginning of each turn; the partner will leave if their salary cannot be paid.<ref name="Manual27"/> The mode can either be played in 20 turns or for an indefinite amount of turns until one of the players' health is depleted.<ref name="Manual2829"/>

The partners do the battling to reduce the opponent's health, and defend the player from incoming attack.  Each partner has its own health, and if it reaches zero, they disappear, and if the attacking partner deals more damage than the defending partner can take, the player takes damage equal to the difference. If no partner is between the attacking partner and the opponent, they take all the damage directly. The characters cannot attack their opponent directly. Some of the partners' attacks cannot be protected against, and each partner costs a certain number of coins for the player to keep it, and if the player has two partners, their salary combines. Occasionally, if a partner is attacked by the opponent's partner, the attack will miss. When the turn count expires, the winner is decided, and it is whoever has more health left. The game will end before the turn count expires if either player's health hits 0. If the turn count expires and both players have the same amount of health, whoever has the most coins wins. If both their health and coins numbers are the same, which is rare, the game ends in a draw.

Duel mini-games and Game Guy mini-games are the only mini-games available to be played on a duel board. Unlike Battle Royale, they do not occur after every turn, but only if either player lands on a mini-game space. There is also a part of each map that makes the players play a duel mini game for 20, 30 or 40 coins after it is passed five times. Game Guy mini-games occur more often here than in Battle Royale. Items are not present in Duel mode.

In the Story Mode to the series, one player starts a [[campaign (role-playing games)|campaign]] through every board, challenging computer controlled opponents at a shortened version of Party Mode. The player's objective is to defeat the other characters and earn stamps from the Millennium Star. After all seven stamps are acquired the player is challenged to a final duel with the Millennium Star, in which the player must hit the Millennium Star three times (six times on Normal difficulty and nine on Hard difficulty) with stars in order to complete story mode. Each time the player completes an objective, they are given a rank of S to C depending on how well they completed that objective. When all the objectives have been completed, a title representing the player's overall progress in the game is awarded. This is determined by the ranks they earned for each objective. If enough "S" ranks are acquired, that character becomes a "Miracle Star" and the Game Guy Room in the Mini Game House is opened for use. Simply beating the Story Mode and not earning a high title will cause the character's face to be sculpted into the mountain.
