How to Play Lights Out
Lights Out is a classic logic puzzle game that challenges your problem-solving skills. Your goal is simple: turn off all the lights on the grid!
- Tap any lit (yellow) tile on the grid
- That tile AND its adjacent neighbors will toggle (on becomes off, off becomes on)
- Keep tapping until all tiles are off (dark)
- Try to complete each level in as few moves as possible
- Levels get progressively harder with more complex starting patterns
Strategy Tips
The key to solving Lights Out puzzles is understanding that the order of clicks doesn't matter - only which tiles you click. Advanced players use the "light chasing" technique: work from top to bottom, turning off each row before moving to the next. The optimal solution often requires clicking tiles that are already off!
Did you know? Lights Out was originally released as an electronic game by Tiger Electronics in 1995. Not every starting configuration is solvable - the game uses mathematically proven solvable puzzles!
