How to play
Rules of the game: instructions step by step
On the screen, you will see a square field divided into cells. Your objective is to make sure that all cells are lit simultaneously.
Actions in the game:
1. Click on any cell to begin the process.
2. A «chain reaction» will occur: the chosen cell and its adjacent cells (above, below, to the left, and to the right) will instantly switch their state — burning cells will extinguish, and extinguished cells will ignite.
3. Keep in mind that diagonal cells remain unaffected — this is important for planning your moves.
4. You win when all cells on the field are glowing.
Strategic advice:
* Begin with the central cells to affect multiple areas of the field simultaneously and reach the goal faster.
* Remember the sequences of moves, as some can undo progress while others can lead to victory.
* You have 5 free hints — use them in difficult situations. Ads will help you refresh these hints.
