How to Play
Pressing a Cell Toggles Its Neighbors
Press a cell to toggle that cell and the cells directly above, below, left, and right. Diagonal cells do not change. A corner affects 3 cells, an edge affects 4, and a center cell affects 5.
Clear the puzzle by turning all lights off, blooming all flowers, or turning every character into an angel. The visuals may change, but the puzzle rules and solution stay the same.
Choose How You Want to Play
- Choose from 3×3, 4×4, 5×5, and 6×6 boards.
- Choose a difficulty range from Easy to Expert.
- Clear a stage to move on to the next one with the same settings.
- If you get stuck, you can use hints or show the answer as often as you like.
- You can reset or give up a stage at any time.
Hints and Answers Are Always Available
A hint shows one cell to press from the current board. Show Answer reveals all remaining cells in a shortest solution. You can still clear the stage normally after using either feature, and their use is recorded in your play history.

Tips
Press the Same Cell Twice to Undo It
This is useful for checking what changes or undoing your previous move.
The Order Doesn't Matter
If you press the same set of cells, the final board is the same no matter what order you press them in.
Start by Watching the Corners and Edges
Corners affect only 3 cells and edges affect 4, making their effects easier to follow.
Work Down from the Top Row
Working through the board row by row from top to bottom can make it easier to narrow down which cells to press.
Think of Each Cell as Press or Don't Press
Thinking of each cell as a simple choice—press it or don't—can make your moves easier to keep track of.
Use a Hint When You Get Stuck
Before pressing the hinted cell, try predicting how the surrounding cells will change. It can help you understand the puzzle better.
