The purpose of your moves
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.
The steps to play
- 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.
Your inputs
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Read the example below alongside these instructions.
One way to understand the rules
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. Look for the relevant detail.
A mistake to avoid
An unlit tile can still be tapped; it may be necessary to solve the board. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
