Cash Flow

Cash Flow is a 1-vs.-3 bonus minigame in Mario Party 6. The name is a pun on "," a term for the transfer of money into or out of a project or business over a period of time.

There are only aesthetic differences between day and night.

Introduction
The players start out on top of the slide as the camera zooms around to the angle shown during gameplay.

Gameplay
Four players must slide down a water slide. The solo player rides on a Koopa Shell-shaped raft, while the team players slide down the slide together.

There are coins and Coin Bags to be collected and Spiny Shells that the players must avoid. Team players that touch the Spiny Shells are eliminated; the solo player is only temporarily stunned if they hit one. The objective is to collect as many coins as possible while the players head down the slide.

Ending
The players perform their victory animations on a beach.
