Play Lights Out with the rules at hand
Read the aim of Lights Out, then make your first move. Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. Keep the game area visible while you use its controls. Compare the starting position with the example in the Guide. Check the relevant rule before repeating a move.
Practice beyond the first move
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
The objective of a round
Turn every light off. Every supplied starting state is made by valid flips from an all-off board and is therefore solvable. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.
From the start of a round
- 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.
Choosing and moving on screen
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
Put the rules into context
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. Keep the controls nearby.
Pay attention to this rule
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
