Gameballs are capsules that come from the Gameball Machine, an item from Mario Party. Their name is a portmanteau of the words "gumball" (a candy item it parodies) and "game." The Gameball Machine appears in the Mushroom Shop after 30 minigames have been bought from the Mini-Game House. Players can buy a Gameball from the machine for 300 Coins.
Every Gameball contains a random minigame that has not been seen or purchased yet at the Mini-Game House. This provides an alternate way for players to unlock all minigames; while the price changes at the Mini-Game House, the price for a Gameball stays at a consistent 300 Coins.
