Stickers
Stickers are the main point in London Party Mode. The first one to get either 16 (about 30 minutes), 32 (about 60 minutes) or 48 (about 90 minutes) stickers win. Players can collect stickers either by winning bonus games and events from characters or rivals, or by obtaining them from bonus balloons.

Stickers obtained by defeating rivals are larger than normal stickers, and can take up four spaces instead of one.

? Effects
In London Party, some of the squares on the sticker sheet on covered with a question mark, where placing a sticker over that space will cause a random effect to happen. As the game progresses, the color of the question marks will change from blue to green to yellow to red, with each subsequent color having more helpful/harsh effects:
 * Bonus Stickers!: An extra Chao sticker will be awarded to the player. Later on, two stickers may be granted instead.
 * ? Change!: A Dark Chao will either add an extra question mark on the sheet, or take one away.
 * Sticker Copied!: Orbot and Cubot will appear and copy a random sticker from the sheet and place it in a random spot, making it similar to the "Bonus Stickers!" effect, except the player does not choose where to put the new sticker.
 * Sticker Lost! (Chain Chomp): A Chain Chomp will attack a random opponent's board, making them lose one sticker. In later rounds, the Chain Chomp's effect will have a greater area, taking away four of an opponent's stickers instead of one.
 * Sticker Lost (Kamek): Kamek will appear and use his magic to take away either one or two rows of the player's stickers.
 * Page Trade!: A Boo will swap the player's current page with a random opponent's.
 * Sticker Gift!: Omochao will grant a sticker to one of the player's opponents.
