SpaghettiMazeMaker is a very simple application that allows you to create mazes with curved lines to print them and solve them on paper, as they cannot be solved directly from the application. The program allows you to select the maze size (width and height) by choosing the number of units and the size of the gates. Then, you need to drag the red and green triangles to set the entrance and exit positions of the maze. Finally, hit the Build button and the program will progressively build the desired maze. The process may take a few seconds, according to the size selected. Once it is ready, you can save it in multiple formats or export it to PDF, but you won't be able to print it directly from the program.
From the Preference menu, you also will be able to customize wall line thickness in window and in PDF file. Unfortunately, you won't be able to paint it with colors, select a background, or anything, which is really a shame.
To conclude, if you like to solve spaghetti mazes and you want to create your own to take them wherever you go, SpaghettiMazeMaker may work for you.
