Bloons TD 6 is a strategy tower defense game where players place specialized monkey towers to pop waves of invading "Bloons." Gameplay involves selecting and upgrading towers on a touchscreen, directly tapping and dragging them onto the map. Managing income and unlocking new tower paths are central to progressing through increasingly difficult rounds.

The mobile version is designed for touch interaction, featuring intuitive menus and controls optimized for smaller screens. It offers a substantial single-player experience with multiple maps, modes, and a deep upgrade system. The core challenge is strategically combining tower abilities to overcome diverse Bloon types and boss events.
