Bowser Gates are giant gates that appear in Mario Party 9. They appear in front of the final Boss Battle Space at the end of each board, except for DK's Jungle Ruins. Most of the time, once the gate is passed through, the players must face a boss. The gate in Boo's Horror Castle has a blockade blocking access through the gate that has the number 6 on it. If that number or higher is rolled, the blockade crumbles and the players can go through. If not, the number decreases by 2 and the players have to make another loop around the board's final section to try again. The gate in Bowser Station does not initially appear until after Bowser Jr. is defeated. When that happens, Bowser creates a Boss Battle Space at the start of the board and summons a Bowser Gate.
