One thing to notice as you play
After a move, check what changed. Decide which rule explains the new state before acting again. Keep the objective visible.
What you need to achieve
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.
Start here and follow along
- 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.
Using the playing area
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
One way to understand the rules
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
Check this before moving on
An unlit tile can still be tapped; it may be necessary to solve the board. Take a moment to reassess the position before continuing. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
