Coin Challenge

Coin Challenge is a free-for-all bonus minigame for 2-4 players in Mario Party 10. Rather than being found in the "Bonus Games" section, it is instead found in the Mario Party mode, at the very end of the game selection screen. Player compete to earn coins based off their minigame results in 3, 5, or 7 rounds of competition.

Introduction
The camera zooms out to the four floors and platforms that are used at the end of a game. The camera then zooms in to the lowest level and shows the characters participating who are next to their colored pipe and a coin counter.

Gameplay
The game starts with the characters competing in a minigame to earn coins based on their position. Each round, a minigame is picked from the minigame wheel that contains 6 random minigames. The minigame is picked randomly for the first round and by the last place player for subsequent rounds. If the difference between first and last is 30 coins or more at the start of a round, the minigame wheel spins slower, making selecting a specific minigame easier. One minigame equals one round, and at the end of each round, players will be able to see how many coins they earned in that minigame and how much they possess after each round, with the exception of the final round, where all there is in each coin counter are three ? marks. Once 3, 5, or 7 minigames have been completed, depending on how many rounds the player has decided to play for, the game ends.

Coin distribution
When playing a 5 or 7 round game, the last two rounds have two Chance Minigames; if one of them is selected, the players earn double the amount of coins normally earned in that round.

Maximum coin totals
For 5 or 7 round games, the maximum totals shown are with zero and two Chance Minigames played, respectively.

Ending
The players enter their colored pipes and the camera rises in height to each pipe corresponding to the ranking. Rankings are revealed from last to first based off who had the most or least coins in the game. If there is a tie for a position, the position in which no one takes that spot is skipped, and the characters that tie will exit the pipe next to each other, doing their respective poses simultaneously based on if they placed first or not. The number of coins that will come out of a pipe is based on the number of coins the player in that place had, and after the last coin comes out, the character will jump out of the pipe and do a victory animation (if placed 1st) or a failure animation (if placed outside 1st). Once the camera reaches the gold pipe and the character jumps out, the words "Congratulations!" appear on the screen; the music used for the result screen is shared with Minigame Tournament.

The Ranking screen in this mode is displayed the same way as the Mario Party mode in a board and in amiibo Party mode, except that they lack Coin, Star or Mini Star symbols altogether and that the player labels that say P1, P2, etc. are merged closer to the character icon. The "View Details" button replaces the "View Graph" button from the other modes, and pressing that button changes the screen to another page that displays how many coins each player won in a specific round; if the respective minigame was a Chance Minigame, the values shown here will be twice as normal for that round.

No matter how many rounds are set, 20 Mario Party Points are always awarded at the end of each Coin Challenge game.
