Magma Mine

Magma Mine is one of the seven boards in Mario Party 9. The players ride in a minecart inside a volcano. The mini-boss is a giant Spike, while the main boss which is fought at the end is a Chain Chomp.

Layout
The players start out at the bottom of the mine, in front of a circle of lava. The players ride around the circle to a large ramp leading up. About midway is the boss fort where the mid-boss Spike in solo mode) is fought. After the battle, the players keep following the track, which goes in different directions (like right and left) to eventually reach the top where the Bowser Gate and a stage boss (Chain Chomp in solo mode) is located. After the mid-boss, the magma shown earlier will rise about to where the players are; it will then rise two vertical spaces each turn after that. It should be noted that, at this point, there are spaces that are exclusive to this board called Magma Spaces. This particular space increases the amount of spaces the lava will raise by the number of vertical spaces shown when landed on. The player who is captain when the lava catches up to the cart will lose half of their Mini Stars. Once the players reach the top of the volcano, the magma will stop chasing them.

Another known gimmick occurs when the players reach a fork in the path (one spot is the circle of lava). Each player chooses which way they want to go (left or right). Each player may choose a direction, and once each player has decided one of the players is randomly selected. If the arrow lands on a player who chose left, the cart will go left. If it lands on a character who wants to go right, the cart would go right. If all players choose the same direction, the vehicle simply moves in that direction without randomly selecting a character. Another note is the strange bone-like creature beside the boss fort, it resembles a Bone Dragon from Yoshi's Story.

Technically, the point of the board is to reach the top as fast as the player can so he or she will not be the victim of the lava.

Dice Block Chicken
In this Captain Event, the players leave their vehicle and board separate mine carts on identical paths. Each path includes several sets of Mini Stars and a cliff at the end. Each player rolls a Dice Block and moves forward that many spaces, although all move simultaneously. The captain can choose to stop before a round of Dice Block rolling begins, and the event ends when the captain either decides to stop, falls off the end of the track, or collects all available Mini Stars. Any players who fall off earn no Mini Stars, and all other players earn however many they collected.

Spike Boss Battle
The players are in the volcano, spike throws spiked balls to the players, they have to point to screen an select a item to throw back the spiked ball to spike and win points, the items are a Golden Hammer (3 pts.), a Normal Hammer (1 pt.), and a stick (-1 pt.).

Chain Chomp Boss Battle
The battle takes place at the peak of mine. The players start out behind minecarts with cannons on them. The Chain Chomp appears in front of the minecarts. The players must choose the correct path to reach a minecart. Once they reach the minecart, the cannon shoots hitting the Chain Chomp thus, giving the player points, 1 if is a normal cannon and 3 if is a Golden one. If the player chooses the wrong path, the Chain Chomp hurts the player and lose 1 point.
