King Boo's Tricky Tiles

King Boo's Tricky Tiles is a boss minigame that appears in Mario Party 10. The boss minigame of Haunted Trail, it pits the players against King Boo.

Intro
The minigame takes place in a graveyard at night. The players are shown standing on stone pillars in a purple lake before the camera pans to the surrounding forest. King Boo is seen moving among the trees, but fades away when the camera focuses on him; suddenly, he pops up right in front of the players, startling them. He waggles his tongue and laughs evilly before the minigame begins.

Gameplay
King Boo will summon a course made of floating blue and red tiles; the players must navigate the course to reach switches that shine lights on King Boo for damage and points; orange switches are worth one point, while yellow switches are worth three. Players are temporarily immobilized while activating a switch, allowing their competitors to make more progress towards activating the other lights. After all available switches are pressed, the players will return to their starting positions as King Boo summons a new course.

To complicate matters, the course also features a few Boos that disguise themselves as red tiles; anyone who jumps on a Boo will fall into the lake below, losing a point before returning to their starting position. The Boos are shown at the beginning of the round before morphing into their tile forms; additionally, the fake tiles will shake periodically as the players race to the switches.

When half of King Boo's health is depleted, he will make the courses more elaborate, with fewer yellow switches and more Boos. At the beginning of each round, he will make one of the Boos switch places with a normal red tile before floating up to the screen and taunting the camera, preventing players from seeing the Boos as they morph into tiles.

The minigame ends once King Boo's health drops to zero - the player who lands the final blow gains an additional five points. After King Boo fades away, the result screen is shown with a sum of points, penalties and bonuses. The player with the most points overall wins the minigame.
