You are Jan playing against Pat. (8 variants, two of them randomized)
 
The board contains many circular pivotal centers of revolving doors which have up to four doors attached to each of them.
 
First each player clicks the board to drop a Man.
He slides to the North, South, East of West as far as empty spaces are available, and always has to go the whole way until he faces a door or the border. You move your Man by clicking the target position. (The arrows at the border are only decoration in this game).
 
If a Man bumps into a door, all doors attached to the pivot will rotate by 90 degrees, either clockwise or anticlockwise, depending how it is pushed. Thereby the board setup is continually redesigned with each move.
 
The door which the Man bumped into, however, disappears. Therefore your Man will end up at the border eventually if it's not caught beforehand.
 
You win if you have captured your opponent's Man.
You loose if you are stalemated and after 3-fold repetition.
 
Variant 4: Click the board to create a randomized setup of doors.
 
Variants 5 to 8 : like variants 1 to 4, but the doors do not revolve.
