Which Mario Party: Island Tour story campaign has players climb a 30-floor tower?

Mario Party: Island Tour’s story campaign is Bowser’s Tower, a 30-floor climb through Bowser’s minigame gauntlet.

The mode is the game’s main single-player-focused adventure. Players choose a character and ascend the tower with Green Toad, facing bubble-created doppelgängers in minigames. The opponents become tougher as the climb continues, turning the campaign into a test of both skill and endurance.

Every fifth floor features a boss-style minigame, with the final confrontation against Bowser on floor 30. Clearing the tower completes the campaign and unlocks Bowser Jr. as a playable character. The story begins when Bowser, jealous that he was not invited to the Party Islands, builds the tower and uses bubbles to disrupt everyone’s fun.

A common mix-up is treating Bowser’s Tower as simply another board. Unlike the game’s party boards, it is a linear solo challenge built around repeated minigame battles. The other choices are not the name of this campaign: Mini-Game Coaster belongs to a different Mario title, while Party Planner Trek and Shroom City are not the campaign’s official name.
