Xor is a strategic game to test spatial insight.
With walkers (shields) all happy masks are to be removed before one reaching the door.

One walker can be moved by clicking next to it (four directions), drag along the row or column and with arrow-keys.
You got two walkers, selectable with "walker" and the Enter-key.
The Delete-key withdraws the last step(s).
"<5" undoes the last five steps.
The "<<" button and the Home key are to restart the game.
"video" is to replay done steps, after an interruption "step" does one next step.
"view" to resize the view in steps between original and full size.
"save" stores the current situation for sixteen days (as a cookie) and replaces an earlier storage.
"load" restores the last, maximal sixteen days old, situation stored with "save". The "load" button is available in a begin situation, as after "<<".

Once started, you can play offline, without an open internetconnection.

The game Xor is created by Paul Carruthers and Ian Downend for the Atari ST and Amiga. Paul formed Astral Software Ltd in 1987.
The player here is a remake of Xor by 'Astral 1981 / JvdLingen 1989' on the Macintosh computer of those days, in 2004 programmed in javascript by Rob Veldhuyzen van Zanten.
In the original Macintiosh game the display is fixed to 7x7 fields, and a restart is required after each misstep, making the goal almost unreachable.
There to start The Cave, one has to type the code, received at the exit of Together.
The player here is tolerant, enjoy your game.

Solutions of the original BBC serie gave letters; 'The Decoder' helped to find a word.
