Ball.io

Players in Ball.io take control of a small circle, navigating a chaotic environment filled with opposing circles. Movement is achieved through arrow keys or WASD, with the goal of shrinking or eliminating other circles to emerge victorious.

The core mechanic revolves around colliding with other circles, which can either grow or shrink the player's circle depending on the size difference. A shrinking circle is vulnerable to being eliminated, while a growing one gains size and influence. Players must adapt to a constantly changing arena and respond quickly to threats.

The objective is to remain the last circle standing, requiring strategic decision-making and reaction time. With its addictive simplicity and surprising depth, Ball.io can be played directly in the browser without download or registration, making it accessible to players of all skill levels.
