Click an empty position to place your man.
A move consists of orthogonally or diagonally walking any length. You cannot walk through walls or cross your own path. (You can, however, pass diagonally between two walls touching at a corner).
You have to change direction with each move.
After each move the length of your step changes by one unit; whether your next step will be one unit shorter or longer is your choice.
However, at least one of your steps during the game must have a certain length which is given on the bottom border; in the default variant this length is eight. When you have used this length, a green button will appear at the bottom rim.

The length of your previous move is also display on the bottom border.
The maximum step length is ten.

Your goal is to walk as many steps (make as many moves) as possible.
The number of your moves as well as the length of the longest known walk (measured in number of moves) are shown at the top border.
You can edit the digits of this limit simply by clicking them (after you dropped your man). To get a win-message, however, the limit must be set to be greater than 9.
These maximum lengths have been found by hand, so you might be able to improve on them.

When SmartMoves is activated, you simply click the target position to move your man. Activate it via View/Options/Board/SmartMoves.

You win when you played the maximum amount of moves.
Solutions are attached.

There are also ten randomized variants attached. In these variants, try to play as many moves as possible; the maximum path length is unknown in these cases.

Note that there are several piece sets available.
