Free ForeverNo DownloadPlay in BrowserMobile Friendly
How to Play
Click a cell to toggle lights according to the active variant. Turn off all lights to win.
Objective
Turn off every light on the grid. Clicking a cell toggles related cells per the active variant. Fewer moves earns more stars.
Controls
• Classic: clicked cell + up/down/left/right (cross shape) • Diagonal: clicked cell + four diagonals (X shape) • Cross: entire row + column of the clicked cell • Self-Only: clicked cell + 8 neighbors (3x3 area) • Undo reverts the last move • Hint: highlights the next optimal cell (limited uses) • Random mode scrambles from a solved state — always solvable • Level mode has 10 progressive levels that unlock sequentially
Tips & Strategy
• Work top-to-bottom: use the row below to clear each row (classic only) • Click order doesn't matter — only odd vs even count per cell • Avoid clicking the same cell twice — it cancels out • Hints use GF(2) Gaussian elimination for the minimum solution; use sparingly • Larger grids and trickier variants raise the challenge • Difficulty system: easy → medium → hard → expert • Stuck? Switch grid size, variant, or difficulty in Settings
