Starting from the central cell of this maze (there's a (3) in it), the challenge is to find a path that leads you off the maze, and to a "star" (*).
The number at each cell shows how many steps, in a straight line, you must take. You can travel horizontally, vertically, or diagonally, up or down, left or right.

The 9-character solution, the shortest one found can be expressed as follows. Again, visited nodes' numbers are prefaced with the time slot (1 more than the step number leading there) at which it is visited, and a directional notation, /, \, ^, v, < or > is placed in the appropriate direction around the original digit to point to the next node on the path:

For a wilder ride, the first solution found took 92 steps. There were 1162 solutions in all that were found. The bias is toward going to the upper left as that's the first direction tried from any node. So there are probably more than 1162 long solutions, without that bias.
