The game has a triangular board with an extra red square at the bottom. This gives the board a funnel shape, hence the name. There are four different types of piece: Rollers, Whirlers, Chargers and SuperChargers. The object is to get a Whirler onto the red square, or to capture all your opponent's Whirlers.

For more detailed instructions, select "Game Description" from the Help menu in the game, or right-click on a piece and read its Properties text to see how it moves and what it does.

There are 14 variants included. 11 of them are two-player, and 3 are one-player.
