Each type of bloon has unique properties, such as different colors and abilities, requiring players to adapt their strategies to effectively pop them. The series began with the original Bloons game in 2006 and has since expanded to include several sequels and spin-offs, such as Bloons Tower Defense. The games are available on multiple platforms, including mobile devices and web browsers, making them accessible to a wide audience of players.
