About Radium
Radium is a physics-based skill game in which you guide a ball through levels using two tractor beams that exert force on it. Some levels require you to collect tokens to activate the exit.
Controls and challenges
Collecting an item changes the ball’s polarization: the interface turns yellow, the ball falls upwards and the tractor beams push it away. The game focuses on its core mechanics, with automatic zoom and scrolling.
Levels
Radium has 130 levels of increasing difficulty.
