Printable Lights puzzles
Lights is a placement puzzle. Put lamps in open cells until every white cell is lit. Lamps never see each other. Each numbered wall must have that many lamps next to it.
Marking lamps
- Use a circle or dot for each lamp and an X for a cell that cannot hold one.
- Draw light pencil lines if you need to trace what a lamp can reach.
- Recount every numbered wall after placing a nearby lamp.
How to play
Place lamps in empty cells. A lamp lights its row and column until a wall blocks the light. Every empty cell must be lit, lamps cannot shine on each other, and numbered walls tell how many lamps touch them.
For a longer walkthrough, see the Lights rules page.
Checking a finished grid
Ask students to check three things in order: every white cell is lit, no two lamps see each other, and each numbered wall has the right count. Keep the answer key separate. More Lights boards are available at LoopAndGrid.com after class.
