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 the opponent giving the winner a 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 an event where they hit a ! Block to stop the roulette. Whatever it shows, the loser gives coins to the winner (10, half, or all of their coins). If the winner lands on the "X", the loser will not give any coins to the winner. In Mario Party 8, the Duel Space is called the VS. Space, and is only found in Star Battle Arena. The player that lands on one plays a Minigame with their opponent, with the loser giving coins to the winner via the dart wheel (also, the shape of the space is different with each board, including the tutorial). In Mario Party 8, about the Dart Wheel-the Dart Wheel becomes 5, 10, or 20 coins for the "attacker" on the Duel Space (or "VS. Space") in Star Battle Arena; the "defender" gets the Dart Wheel which has 1, 5, or 10. 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, they will usually challenge the player in first place (or second place if the player who landed on it is in first place) to duel them. Additionally, if the player lands on this space, hitting Random will usually select the CPU player in first place (or second place if the player is in first place).
