About this template

Place lamp symbols so every white cell is illuminated along its row or column, stopping at dark walls. A miniature cross shows how light stops at a wall; a wall clue counts lamps immediately above, below, left and right. Lamps may not shine on one another. Starter uses four-by-four, Growing five-by-five with more walls and interacting clues. Both original boards have a unique lamp layout. The separate key marks lamps and lit cells.
