About this game
Lights Out is a puzzle where pressing a cell flips that cell and its up/down/left/right neighbors, and clearing all the lights wins the stage. As stages rise, the grid gets bigger and more lights start on.
How to play
- Continue from where you cleared on the stage select screen.
- Press a cell to flip it along with its up/down/left/right neighbors.
- Drag to flip every cell you pass over in a row.
- Turn off all the lights to clear the stage.
- Use a hint to see the next move if you get stuck.
Tips
- Solving within the par move count earns a bonus score.
- Going over par costs points for each extra move.
- Using a hint reduces your score, so save it for when you're stuck.
- Edge cells affect fewer neighbors, making them a good place to plan your order from.
- Pressing the same cell twice undoes it, so keep track of what you've already pressed.
FAQ
- Can I continue from a stage I already cleared?
- Yes, the stage select screen lets you continue from where you left off.
- How is the score calculated?
- The clear base score adds a par bonus, then subtracts points for going over par or using hints.
- Can I play for free with no install?
- Yes, you can play right in your browser for free.
