The core mechanics of the series revolve around its tagline, "Play, Create, Share."
The Play component involves players taking control of Sackboy and navigating him through various levels. In the first two installments of the series, gameplay consists primarily of traditional platforming like jumping and avoiding obstacles to successfully navigate to the end of a level to win. Since LittleBigPlanet 2, the game has expanded to being a "platform for games" with the introduction of numerous mini-games and other genres into the game diversifying the game from being strictly a traditional platformer. Most LittleBigPlanet games involve a player playing solo or co-operatively with friends to navigate through a level whilst collecting various "bubbles" along the way. These bubbles come in two types, small ones which constitute points and larger ones that contain new costumes, stickers or other types of collectibles that can be used to customize Sackboy or create levels. There are also numerous co-operative parts of levels whereby certain prize bubbles can only be collected with the help of at least one player or more depending on the number of players stated in the level.
