Object: Visit all positions on the board, i.e. delete all green dots. (4 variants, one of them randomized)
 
The board contains many circular pivotal centers of revolving doors which have up to four doors attached to each of them.
 
To start, click the board to drop your 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 can either move your Man by clicking the target position, or by clicking one of the arrows at the border.
 
If the 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 white doors are made out of glass. If the Man bumps into a glass door, it shatters. The missing door can make his roaming more difficult.
 
Whereever your Man goes, the tiny green dots on his position will disappear.
You win if you have captured all green dots on the board.
You lose if you are stalemated.
 
Variant 4: Click the board to create a randomized arrangement of doors. Not all such randomized setups may be solvable.
 
 
Watch out that you do not get stuck in the hallways at the border.
In some cases it is important where you place your Man in the first move.
Leave the glass doors intact as long as possible. Sometimes braking a glass door at the wrong time makes solving the puzzle impossible.
