Gameplay
The main style of gameplay is the Board Game, which features a massive gameboard consisting of dozens of panels. The objective of the game is to have as much money as possible when every tile belongs to a player. Each player has two varieties of money - the money earned from winning a minigame and the money earned from simply owning a panel. Note that while the latter is easily increased (and just as easily decreased), only three effects in the entire game can affect the former.
Each of the four players take turns uncovering panels around the gameboard; who goes first is determined by a minigame at the beginning that takes place at the center panel. While at the beginning, players can only uncover panels that are close to the central one, as the game goes on, more panels may be uncovered. A panel owned by a player is marked by being bordered with the player's colors; if the color is gray, then nobody owns it and anyone can select it.
