Physics Ball is a puzzle game where students draw lines to guide balls into a container while collecting all the stars along the way. In Single Ball Mode, players use a limited amount of ink to draw paths and barriers that help one or more balls reach the container. Since the drawn lines remain fixed, students must carefully plan their designs to guide every ball and collect every star. In Multi Ball Mode, gravity affects the movement of the balls, creating an additional challenge. Players must guide the red ball into the container while keeping the black ball out, all while collecting every star and staying within the ink limit. The game develops K–5 mathematical skills such as spatial reasoning, geometry, problem-solving, prediction, and strategic planning. Students learn to analyze movement, anticipate outcomes, and optimize their designs using limited resources.
