Mario Party 2 has 65 minigames when course variants are excluded.
The sequel contains 15 more minigames than the original Mario Party, which had 50. That brings the standard count to 65 distinct minigames. Some games include alternate courses or variations that are counted separately in an expanded total of 88, which explains why different references may display a larger number.
The 65-game count is the appropriate answer when the question asks for minigames while excluding course variants. The collection spans the familiar four-player, 2-vs-2, and 1-vs-3 formats, while also adding Battle, Item, and Duel categories. These new types helped distinguish Mario Party 2 from its predecessor.
The minigames are used primarily at the end of board-game turns, with the space colors determining the match format. They can also be purchased from Woody and played outside the main board game. Once enough have been collected, players unlock Mini-Game Stadium for multiplayer competition and Mini-Game Coaster for single-player progression.
