About Light On

Light On is a puzzle game in which you play as a cat engineer travelling through countries including Hong Kong, Taiwan and Egypt. You connect cables to light up houses, while managing each building’s maximum power supply. The game has over 120 puzzles set among scenery from around the world.

Power puzzles

Place and remove connections to route electricity without overloading a building. Puzzles introduce mechanics including multipliers that increase the electricity sent to a building, tunnels that transmit power, and redirectors that change its direction, alongside other features and special mechanics.

Worlds and comics

The houses have different styles and layouts in each country. After finishing each world, you can collect a comic book.
