Lights Out: a guide for your next round
Try Lights Out at your own pace and keep its objective in view. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Choose a clear next step rather than rushing through the instructions. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.
Give this approach a try
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.
The goal to keep in mind
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. The feedback beside the game helps you follow the round. Review the board or playing area as it changes.
Follow these playing steps
- 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.
The controls to know
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Use the visible help when you are unsure of the next input.
An example before you play
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Use the example as a guide rather than a substitute for reading your board. Verify the rule before continuing.
Avoid this misunderstanding
An unlit tile can still be tapped; it may be necessary to solve the board. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
