Option 1: Play with the test image loaded above. Try drawing extra walls, or moving the start and end location.
Option 2: Paste a maze image. Try looking up a maze image on Google Images, and copy the image.
Background must be white
Walls must be black
Start location must be red (or use Set Start Location tool)
End location must be blue (or use Set End Location tool)
If an image doesn't paste cleanly, use a 3rd-party image editor to adjust brightness / contrast, and colors.
If needed, draw supplimental maze walls using the "Draw Walls" buttons, or use the "Erase Walls" button. Keep in mind that the solver will find the shortest path, which might be to go completely around the maze, which means that "Start" and "End" must be dammed apart or walled in.
Option 3: Use the simple drawing tools to draw a maze. Be sure to set start and end locations.
Click the "Analyze" button. If the analyzer can find start and end locations, click "Solve", otherwise click "Revert" and modify the maze image as necessary.
Once the path seeker finishes, if no solution is possible, a message will be displayed, and the simulation ends. Otherwise, click "continue" to enter the retrace phase (purple line).
