Your files are loaded into your device's memory, processed instantly by your local CPU and GPU, and saved directly to your disk, ensuring zero data leaks, zero server logging, and immunity to malware execution.
Guia passo a passo
Study the Grid

Toggle Lights
Click any light to toggle it and its up/down/left/right neighbors on or off.
Turn Everything Off
Keep toggling lights strategically until every light on the grid is off. Fewer moves means a better result.
