List of Mario Party pre-release and unused content

This is a list of beta elements in the game Mario Party.

Unused data
In addition to the 50 minigames that appear in the final product, Mario Party was also planned to feature a number of other games that ended up being discarded. The character mugshots for all characters initially looked different; Donkey Kong's initial mugshot showed just a silhouette of the character with a question mark, as Nintendo probably had to wait to obtain licensing for Rare's 3-D version of the character when the game was in its early development stages. The early character mugshots can be seen in the game's debug menu.

Among the dropped minigames are:
 * All or Nothing (いちかばちか Ichi ka Bachi ka), a game that depended largely on luck. It was probably an early version of Chance Time.
 * Tour de Mario (ツールドマリオ), possibly planned to be a cycling game.
 * Bungee Jump (バンジージャンプ)
 * SameGame (さめがめ), a Mario-themed take on the tile-matching puzzle game of the same name. The player must Ground Pound the tiles underneath their character to remove sections. If the character can clear all of the tiles, they can grab the treasure chest underneath; otherwise, they must go through one of the doors, which will only give them 1 coin.
 * Yoshi's Tongue Meet (ヨッシーのしたあわせ Yosshī no Shita Awase), in which characters sit atop a Yoshi on the left side of a river (except for Yoshi himself, who just stands in the same pose without a rider). The Yoshis have baby Wigglers on their tongues, which extend to the Wigglers' mothers, and they must reunite the children with their parents. The reunion can only happen if the A Button is pressed at the right moment; if it comes too late, the baby will kick its mother into the bush.

The game was once planned to feature a "Random Play Mode", in which random minigames are played one after another. There would be no board, no explanation screens, and no results screen. The positions of characters were to be determined at random, displayed on the screen using "MAIN" and "SUB". It is possible this mode was merely a debug test of the minigame randomization feature used at the end of each turn.

At one point, there was planned to be another feature that is never used anywhere in the final game. The Player Panels were once planned to turn yellow under certain circumstances after the character's turn ended, which would imply that there were once going to be yellow spaces on the boards as well as red, blue, and green. If all characters' Player Panels turned yellow, a big sign would appear reading "NO GAME", and the game would move on to the next turn without playing a mini-game. If it was the final turn, a "GAME OVER" sign would appear, and then the board's usual ending would play.
