Printable 5x5 Light Up Puzzles (Easy)

The smallest Light Up puzzles we print. A 5x5 grid is the right place to learn the rules, and it suits younger solvers, a classroom warm-up or a quick coffee break.

This first pack has eight Light Up puzzles with an answer key on the second page. Each grid has 5 to 6 black walls.

How to solve

  • Light every cell: Every white cell must be lit by at least one bulb.
  • Bulbs never see each other: Two bulbs may not share a row or column unless a wall sits between them.
  • Numbered walls: A number on a wall says how many bulbs touch it on its four sides.
  • Plain walls: Walls without a number can have any number of bulbs next to them.

Free to print and copy for home, classroom and library use. Every puzzle has one answer you can reach by logic alone.
