The fixed board setups are the ones from games 'Straight' and 'Straight-Across'. All target lengths have been increased by one, though.
The system will try to find a path of given target length. It it finds such a path, the system stops and shows the solution.

You start the automatic search by clicking the 'S' at the center top.
Before you start the automatic search you can
- edit the target length by clicking the digits
- place your man on a board position (note the the system will then not use any positions to the left or below as a starting position!)
- edit the board by adding or deleting any blocks.

A move consists of walking straight to an empty position until you encounter an obstacle. An obstacle can be a coloured square block, the border of the board or your own path. In this case you can turn 90 degrees (left or right) to either side.

Variant 1-24: fixed board setups from game 'Straight'. Each position can be visited only once.
Variant 24-48: HERE THE PATH CAN ACROSS ITSELF. Fixed board setups from game 'Straight-Across'
