How to play Lights Out
Make Lights Out your next activity in the game library. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Use the example below to understand a decision. Keep the instructions close while learning this activity. Keep the game area visible while you use its controls.
Build a steady rhythm
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Keep the objective visible.
Your goal
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. Check the rules when you are unsure.
Step by step
- Select a light or an unlit tile.
- The selected tile and its orthogonal neighbours switch state.
- Plan flips so that previously cleared rows stay cleared.
- Use Undo to try another approach.
Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Contact us with the game and device if a control does not respond.
A useful 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. Keep the game’s format in mind.
Watch out for this
An unlit tile can still be tapped; it may be necessary to solve the board. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
