KnotPlot is an innovative educational puzzle game that focuses on topological concepts through interactive challenges. The game invites players to manipulate nodes and lines to untangle complex structures without crossing paths. It features 30 carefully designed levels that range from simple knotted curves to intricate multi-loop configurations, encouraging players to enhance their spatial reasoning and mathematical skills. Additionally, the game provides a Sandbox Mode, allowing users to create their own shapes and experiment with topology.

The Sandbox Mode is particularly engaging as it enables players to add nodes and connect edges freely. The built-in topology engine enhances the experience by calculating crossing numbers and Euler characteristics in real-time, offering immediate feedback on the mathematical properties of the shapes created. This combination of structured levels and creative freedom makes KnotPlot a unique tool for learning and exploring mathematical concepts.
