The LEGO Ninjago Spinjitzu theme is a segment of the larger LEGO Ninjago line, emphasizing sets centered around spinning-top mechanisms. Each set typically includes a minifigure and a spinner device. The user can place the minifigure inside the spinner and then launch it, causing the figure to spin rapidly. This spinning action allows for interactive battles and challenges with other spinners, blending traditional LEGO building with a game-like element rooted in the Ninjago narrative of mastering Spinjitzu techniques.
LEGO Ninjago, also known as Ninjago: Masters of Spinjitzu, theme was introduced in 2011 and included sets that are based off of original storylines, a TV series and The LEGO Ninjago Movie, a movie based on the theme. The main premise of the Ninjago universe is based around six teenage Ninja, Kai, Jay, Cole, Zane, Nya, and Lloyd, who have been trained by their master Sensei Wu, fighting forces of evil to protect the land of Ninjago.
