I reckon this is easier to see (where you're going, when you've come to a dead end, etc.) if you use a 'bigger' character than '*', e.g. '#'. ########################################### B ## # # # # # ### # ### ## ## #### ## # #### # ### # # # # ## # # # # # # # # # # # ## ###### # # # #### # # # #### ## # ### ### # # # ## # # ## # # # # # ## #### ## ####### # # # ### ## # # # # # # # ##### # # #### # # # # ## ## # ##### # # ## ## # ## ## # ## ######## # # ###### # # ### ### # # #### ########## # # ### # # ## # # ## # # ##### ## # ### # ### # ## ## # # ##### # # # # # ## ## ## ### # ### #### ## # ## # ###### ## ## # # # # # ## ## # ##### # ### # # #### ## # # # ### # # # # # # ### #### # # # # ## # # # ## #### # # ### # # # # # ## ## # # # # ## ## ########## # #### ######### # ## # # # # ## ## E ########################################### ___ _ _a' /( <.

Depends on your font. # and * are about the same size in mine, neither works well for this. I think @ and 8 are good choices for just about every font, but here's something I liked even more: (produced by running the command line sed "s/#/[]/g" maze | sed "s/ / /g" It's > 80 columns, sorry 'bout that) [][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][] B [][] [] [] [] [] [] [][][] [] [][][] [][] [][] [][][][] [][] [] [][][][] [] [][][] [] [] [] [] [][] [] [] [] [] [] [] [] [] [] [] [] [][] [][][][][][] [] [] [] [][][][] [] [] [] [][][][] [][] [] [][][] [][][] [] [] [] [][] [] [] [][] [] [] [] [] [] [][] [][][][] [][] [][][][][][][] [] [] [] [][][] [][] [] [] [] [] [] [] [] [][][][][] [] [] [][][][] [] [] [] [] [][] [][] [] [][][][][] [] [] [][] [][] [] [][] [][] [] [][] [][][][][][][][] [] [] [][][][][][] [] [] [][][] [][][] [] [] [][][][] [][][][][][][][][][] [] [] [][][] [] [] [][] [] [] [][] [] [] [][][][][] [][] [] [][][] [] [][][] [] [][] [][] [] [] [][][][][] [] [] [] [] [] [][] [][] [][] [][][] [] [][][] [][][][] [][] [] [][] [] [][][][][][] [][] [][] [] [] [] [] [] [][] [][] [] [][][][][] [] [][][] [] [] [][][][] [][] [] [] [] [][][] [] [] [] [] [] [] [][][] [][][][] [] [] [] [] [][] [] [] [] [][] [][][][] [] [] [][][] [] [] [] [] [] [][] [][] [] [] [] [] [][] [][] [][][][][][][][][][] [] [][][][] [][][][][][][][][] [] [][] [] [] [] [] [][] [][] E [][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][] -- "Ogre is such a strong word" - Lisa Simpson
Here's something I did ages ago. It's a way of doing non-simply connected
mazes on an ASCII screen. It takes a bit of getting used to, but you can
make a pretty difficult maze fit in a screen.
Rule: go from the arrow-head of your choice to the first arrow-tail
that points in the same direction.

The shortest path has been marked with + instead of -
and I instead of |.
