Editing Mario Party 8

If one player encounters another while under the effects of Duelo Candy, or lands on a [[Duel Space|VS Space]] (Star Battle Arena/Duel Battle only), they will duel in a 1-on-1 minigame. The winner throws a dart at a spinning wheel to determine what prize they collect from the loser. If the challenger wins, they will be able to take Stars or coins, whereas if the other player wins, they will only be able to take coins.

Star Battle Arena is the solo story mode in ''Mario Party 8''. The player chooses a character and competes against five CPU-controlled characters over five separate duels. Each of the five regular boards are played in order: [[DK's Treetop Temple]], [[Goomba's Booty Boardwalk]], [[King Boo's Haunted Hideaway]], [[Shy Guy's Perplex Express]], and [[Koopa's Tycoon Town]]. Lastly, the sixth, unlockable board, [[Bowser's Warped Orbit]], is played for a final showdown. The general rules of Duel Battle are used for all six duels (players take turns without regular minigames), and each duel has a different victory condition from the Party Tent's Battle Royale and Tag Battle. As the player progresses through the duels, their CPU-controlled opponents become more adept. If a duel runs over after 30 turns, Ballyhoo will end the game and declare a tie (like in Solo Cruise from ''Mario Party 7''). All boards are smaller in this mode.

 

Playing Duel Battle in the Party Tent will also allow the player to play this mode against another player or CPU.

|Players move across this board to get a star in a random location in this board. Stars always cost 20 coins each, and whenever a player obtains the star on the board, another star appears in a different location. Landing on a DK space in this board causes DK to throw the player directly towards the star, and landing on a Bowser space will cause the star to warp to a different location. To win in Star Battle Arena or Duel Battle, the player must collect two stars before their opponent does, and the stars are 20 coins each.

|Players move through this linear board to get to the end. At the end, [[Captain Goomba (Mario Party 8)|Captain Goomba]] gives the star to the player for free, as a reward for reaching this far. After receiving the star, the player will get transported back to the start via gulls carrying a wooden plank. Dolphin Expresses in the course can take the player closer to Captain Goomba by paying a fee. The fee depends on what place the player is currently in, with first place having to pay the most while fourth place must pay the least. Landing on a DK space will give the player a chance to earn coins, while landing on the Bowser space will give the player a chance to lose coins. To win this board in Star Battle Arena or Duel Battle, since the player's goal is to get one star from Captain Goomba costing 50 coins, the player must have that number of coins and reach him first for the star, before their opponent does.

|Players move through a mansion to try to find [[King Boo]] and get a star from him. Out of three rooms in the house, King Boo is in one of them. If the player stumbles in other rooms where King Boo is not hiding in, [[Red Boo]]s come and toss the player in a hole, thus making the player go back to the start of the mansion. King Boo offers the star for ten coins once the player reaches him. After paying for that, everyone is taken out of the mansion for another shuffle with different rooms in the mansion. If the player lands on a DK space, DK will cover up the hole and offer the player who comes to an empty room a free star; if the player lands on a Bowser space, Bowser will cover up the hole and will steal a star from the player who comes to an empty room. In Star Battle Arena or Duel Battle, the winning condition required is to acquire two stars from King Boo for 10 coins each by finding him two times.

|Players move through a train to get to the conductor of the train, who will offer a Star for 20 coins. The train board is linear, and therefore, there are no branching paths. After being offered for the star, the player travels on top of the train and back to the start (unlike Goomba's Booty Boardwalk, where the player instantly travels back to the start). If someone lands on a DK space, DK will be in charge of the train and offers a free star to anyone who the first player who reaches him. If someone lands on a Bowser Space, Bowser will take over the train and steal a Star from the first player who reaches him. In Star Battle Arena or Duel Battle, in order to win the game, since there is only one star and it is worth 50 coins, the player must obtain that amount and reach Holly Koopa (not the conductor, who will give the player 10 coins instead) for the star before their opponent does.  

|In this board, players invest money in hotels in order to earn stars. If a hotel has 20 coins invested into it, it upgrades and makes the number of stars it can offer increase to two. If a hotel has a total of 50 coins invested, it can offer three stars. When a player lands on a Donkey Kong space, Donkey Kong will come and help invest coins. Adversely, when a player lands on a Bowser space, Bowser will take coins away from a selected hotel. In Star Battle Arena or Duel Battle, the player has to get four stars by investing in hotels in order to win.

|There are no stars in this board, and so players are given five stars at the start on Battle Royale (in a team on Tag Battle, they are given ten stars). Players must use the [[Bullet Candy]] and [[Bowser Candy]] (which are exclusive to this board) to steal stars from opponents. The board is also linear; no branching paths exist (if one does not count the random branching paths in some parts of the board that the player cannot choose to take). In Star Battle Arena or Duel Battle, the player and their opponent start off with three stars. The winning condition is to reduce their opponent's stars to zero stars by eating candy to steal stars from them. This board is unlocked by completing the entire Star Battle.

|If the player uses it, they will transform into a vampire version of the character. They can take coins from other players chosen by the Dart Wheel. Unlike the Cashzap Candy, the player will actually take coins from the other players. The number of coins taken ranges from 1, 5, and 10 (5, 10, and 20 in Star Battle Arena or Duel Battle). After the player takes the coins from their opponent, the coins that they stole from their opponents get deposited into their bank.

In the Minigame Tent, players can play all of the [[minigame]]s they have unlocked in the [[Party Tent]] or [[Star Battle Arena]]. Duel and Challenge minigames can only be unlocked in the Star Battle Arena during solo play, or in the Party Tent when using a [[Duelo Candy]] or playing Duel Battle. Completing minigames earns the player cards for the player to spend at the Surprise Wagon. There are a total of five ways to play the minigames, as detailed in the sections below.
