Objective: Turn off all the lights on the grid. When you click a cell, it toggles itself AND its adjacent neighbors (up, down, left, right) between on and off.
Basic Strategy:
- Start from one edge (top or bottom) and work your way across
- Focus on turning off lights in the top rows first, then solve the remaining pattern
- Every puzzle has a solution — some may require more moves than others
- Clicking the same cell twice undoes the effect — avoid redundant clicks
Advanced Tips:
- The order of clicks doesn't matter — only which cells you click
- Each cell only needs to be clicked 0 or 1 time in the optimal solution
- Corner cells affect only 3 cells, edge cells affect 4, center cells affect 5
- Look for patterns: if a row is almost solved, figure out which click cleans it up
Buttons: Reset Puzzle restores the current puzzle to its starting position (moves reset too). Pause freezes the timer and the board.
