I won EVERY minigame in an online board game of Mario Party Superstars and unlocked the Minigame Pro achievement! This happened by complete accident too.

This video showcases the entire match. The map is Peach's Birthday Cake and it is set to 15 turns with bonus stars on. Practice sessions and parts where players went idle are edited out. One of the players had an iffy connection, so there is some lag.

If you just want to see the minigames, I have them all laid out in the timestamps so feel free to skip the board turns.
