Multiplier Maze is a puzzle game for PC designed to teach students about fractions through dynamic visual representations of magnitude that exemplify what it means to multiply by a fraction. In the game players must find a way through a maze by removing blocks on the path and escaping through narrow passageways. Players must strategically collect and use items that allow the player icon to grow larger and shrink smaller. Each item has two possible values: a whole number (e.g. 2) and it’s reciprocal (1/2). When using an item, the player choses between the two values and multiplies player icon’s width or height to shrink or grow proportionally. Unlike many math games with the goal of training the automation of fact retrieval, the design of the Multiplier Maze is aimed to support the conceptual learning of reciprocals, the multiplication of fractions as scaling, and the perceptual acuity of ratios.
