At first, he only has a red balloon, but at 10 stars, he gains a blue balloon. For every 10 stars collected, Luigi, will gain new balloons for his case. Each time the player ranks up, they receive a sum of Coins the higher rank they become, the more Coins are awarded. The player's rank is represented by stars, which are awarded for each objective that is completed. The minigame also features a ranking system, which shows the statistics of the player, such as how many Coins they received and how many balloons they found in a row. The icons for the balloons depend on the player's Nintendo Switch profile icon (for example, if a user has an image of Mario as their profile icon, then their balloon will have an icon of Mario on). Finding as many balloons as possible will result in the player's rank going higher and they will receive more coins.

"Find It" mode, which the player has to try and find other players' balloons, with an arrow pointing towards the balloons' direction, as well as a meter increasing and decreasing depending on how far the player is, and "Hide It" mode, which the player has 30 seconds to hide a balloon for another player to find. There are two different modes in the minigame. This is Luigi's only appearance other than the Luigi outfit. To start the minigame, the player has to talk to Luigi in any of the kingdoms (with the exception of the Cloud Kingdom, Ruined Kingdom, Dark Side and Darker Side) after finishing the main story to begin. Balloon World (called Luigi's Balloon World in the Nintendo Mini Direct trailer) is a minigame which was added in Super Mario Odyssey in an update on February 21, 2018.
