Duel Space

"You'll see Vs. Spaces only in Duel Battles. Land on one and you'll face your rival in a minigame!"

- MC Ballyhoo

A Duel Space is a type of space featured in the Mario Party series. It first appears in Mario Party 5 as a capsule that players can place on a space. Anyone who lands on a space containing the Duel Capsule chooses an opponent to duel with, then what the wager will be. However, players can also choose to put Stars on the line, whether it is for obtaining an opponent's Star for 40 coins, or a Star for a Star.

In Mario Party 6, Duel Spaces are already placed on the board, and landing on them has the same effect. The Duel Space in Mario Party 7 is different though; gameplay is the same, but instead of picking the stakes, the winner does a little event where they hit a ! Block to stop the roulette. Whatever it shows, the loser has to give away (this is similar to the Round of Miracles). In Mario Party 8, the Duel Space is called the VS. Space, and is only found in Duel Mode. The player that lands on one plays a Minigame with his or her opponent, with the victor taking coins from the loser via the dart wheel (also, the shape of the space is different with each board, including the tutorial). In Mario Party DS, the Duel Spaces appear only after the Final 5 Frenzy, as a replacement of the Friend Spaces.

In some of these games, players get to decide whom to duel against. However, if a CPU player lands on this, he or she will usually challenge the player in first place (or second place if the player who landed on it is in first place) to duel him or her.
