Klotski Puzzle Game (3-Horizontal 2-Vertical Student Edition)
2020-11-22 12:24
This GeoGebra applet demonstrates the classic Klotski sliding block puzzle. Using polygons and points, it constructs the game board, various sized blocks, and boundary walls. Users can drag the blocks to find the optimal solution while the system tracks the number of moves. This example showcases how to use GeoGebra's interactive features, conditional visibility, and scripting to implement complex
