Lights Out®, by Tiger Electronics is a calculator sized
electronic game. It consists of a 5 by 5 grid of
illuminated buttons. Pressing any button changes the
state (lit or unlit) of the button and also changes
the state of the buttons to the left, to the right,
above and below.
The initial configuration changes as the user completes
the puzzles. The machine keeps track of which puzzles have
been completed within a "reasonable" number of moves.
The device is attractively packaged, the box and the buttons
are of high quality and this adds to the charm of the game -
even the (optional) bleeps sound OK.
The game is absorbing even addictive - playing over
the web (even with minimal lag) does not do justice, the
look and feel of the original are important. The actual
game play is initially captivating however it is "crackable"
after some experimentation as it based on Abelian groups.
Two minor complaints, all the lights flash off momentarily when
a button is pressed and it sometimes misses one press if two
or more keys are operated simultaneously
The game is produced by Tiger Electronics (UK), Belvedere House, Victoria Ave,
It is available in Woolworth's - rather over-priced at £16.

A variation on the puzzle in which there are four states (rather than
two). Each click rotates the arrow (clockwise) and also rotates the
arrow pointed to (if any).
