Lights Out: instructions and practice

Choose a round of Lights Out and settle into its rules. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Check the relevant rule before repeating a move. Treat the first round as a chance to learn the controls. Look at what changes after your first action.

Try a more deliberate round

Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.

The challenge in front of you

Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.

Start here and follow along

  1. Select a light or an unlit tile.
  2. The selected tile and its orthogonal neighbours switch state.
  3. Plan flips so that previously cleared rows stay cleared.
  4. Use Undo to try another approach.

The controls to know

Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. A new-round button replaces the current round.

Try this example

Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Read the matching step again.

One detail worth checking

An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
