Click an empty position to place your man.
A move consists of orthogonally walking any length. You cannot walk through walls or cross your own path.
You have to change direction with each move. After each move the length of your step must increase or decrease 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 a certain mandatory length which is given at the bottom border. In the default variant it is six units. When you have used this length, a green button will appear at the bottom.
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.

The length of your last step is also displayed at the bottom border.
The maximum step length in any move is ten.

Your goal is to walk as many steps (make as many moves) as possible, and include at least one step of the special mandatory length.

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. These maximum lengths have been found by hand, so you might be able to improve on them. If the task seems to be too difficult to achieve, find your own best result and then try to beat it.

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

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.

The name 'Adec' is an abbreviation of 'accelerate and decelarate'.
