Infernal Tower

Infernal Tower is a board in Solo Mode from Mario Party 6. This is the Bowser board of the game, decorated with his personal icon and surrounded by lava, much like other Bowser boards in the series.

The ? Spaces are in front of steel doors. Landing on one causes a Chain Chomp to come out and bash the player back to start.

If a player goes past the last space of the board, they stop at a small platform. This activates a trap, causing a cage to fall on the player, who is then carried away by Bowser in his Koopa Clown Car. In the process, the player loses all possessions.

Trivia

 * Infernal Tower is the first Bowser-themed board which does not have Bowser's name in the title in English, Spanish, German and Italian versions (the second one being Chaos Castle).
