Mega Sledge Bro's Card Chaos

Mega Sledge Bro's Card Chaos (shortened to Sledge Bro's Card Chaos in the British English version) is a boss minigame appearing in Mario Party 10. It takes place in Haunted Trail and pits players against a Mega Sledge Bro.

Introduction
The minigame takes place at night, in a stone arena with torches illuminating a small bridge in the center. The Mega Sledge Bro is shown standing atop a cliff overlooking the arena—he leaps down into the center of the arena but gets his feet stuck in the ground. He yanks himself free before stomping up to the players and beginning the minigame.

Gameplay
Players are presented with several cards, each with an image of Bullet Bills or a Hammer Bro hammer. They have five seconds to memorize the cards before they are flipped over. The Mega Sledge Bro proceeds to remove two random cards with a quake attack, after which the players must choose a card to attack the boss with. The order of attacks is based on who picked their card the fastest (i.e., the first player to pick a card gets to attack first). Anyone who picked a Bullet Bill card gets to attack with the number of Bullet Bills shown on the card, earning one point per hit; anyone who picked a hammer card gets hit by a hammer thrown by the Mega Sledge Bro, losing one point. After each player chooses their card, they can pick one of the remaining cards. After eight cards (six cards if two or three players are playing) are chosen, the process repeats. From this point onward, the cards are replaced with a new batch after four cards are chosen.

When the Mega Sledge Bro loses half of his health, he roars at the players and automatically replaces the current set of cards with a new set. From now on, there are cards with two hammers in the mix; anyone who picks one of these is hit with a pair of hammers and loses two points. The Mega Sledge Bro also removes four cards each turn instead of two.

The Mega Sledge Bro can take 30 Bullet Bills before being defeated. The player who fires the final Bullet Bill receives five points for the last hit. The player with the most points overall wins the minigame.

Ending
After gaining the last hit, the Mega Sledge Bro loses his sight and balance, then falls onto his back before exploding.
