Dinger Derby

Dinger Derby is a 4-player minigame in Mario Party 5, and returns in Mario Party: The Top 100. The name is a variation of the real-life Home Run Derby.

Introduction
The camera is zoomed in on one of the players, and zooms out as each of them takes a practice swing, then hits a baseball.

Gameplay
The players have 30 baseballs thrown at them by a pitching machine and must hit as many of them as possible. There are four types of pitches: a standard pitch, a fast or slow ball, and a screw ball that wobbles furiously. If two balls come toward the character, it counts as one ball, since the player can hit only one of those two. If the player manages to hit a ball at one of the spectators, the spectator will be dazed for a moment.

Decathlon
This minigame appears in the "Decathlon" modes on both games. It is the sixth minigame in Mario Party 5, and the first minigame in Mario Party: The Top 100 when playing just 5 minigames. Here, the player's objective is to hit as much balls as possible to earn as much points as possible, up to a maximum of 1,000. In both games, a player can get a 1,000 if they can hit all 30 balls. The default record for this minigame in Mini-Game Decathlon is 17 points (10 in The Top 100).

Mario Party: The Top 100's Scoring System
Players earn ~47.368 points times the number of balls hit for the first 19 balls; after 19 balls, the player will score 900 points plus another ~9.091 points for each additional hit. Decimals are rounded down.

The scoring in Mario Party: The Top 100 is much more lenient; a result of 20 gives the player 909 points; the same result in Mario Party 5 only gives the player 500 points.

Ending
The camera changes angle and the bats disappear. The players then perform their victory/losing animations as the crowd cheers and confetti and balloons appear to commend the winner's/winners' success. If any player manages to hit all 30 balls, a parachute with a 30 on it will appear. There is no ending in the Mini-Game Decathlon variation; the screen fades to white before the results are shown.
