Flip lamps until every one is dark.

Tap a lamp to flip it and the lamps next to it. Leave every lamp dark. Today's room is the same grid for everyone. Practice opens larger rooms as you clear them.

How to play

1. Tap a lamp to flip it, and the lamps above, below and beside it. On a keyboard, arrows move and Space flips the lamp you are on.
2. The room is done when every lamp is dark. Order does not matter, and flipping a lamp again puts it back. Undo takes back the last flip.
3. To turn a lamp off, flip the one below it and work down the room. The top row is the choice that makes the last row go dark. The fewest flips earns a higher star.
4. Today's room is one grid for everyone, and finishing it once a day grows your streak. Practice opens larger rooms as you clear them. Pause stops the clock.

Every way to play is equal here: touch, mouse and keyboard all move at the same top speed. A score means the same on any device.

Tips

• Flip a lamp twice and it is as if you never flipped it. Look for a short set, not a long path.
• Settle one row before the next. A lamp that is on is turned off by the lamp below it.
• Undo puts the last lamp back. The clock keeps running until you pause.
• Three stars means the fewest lamps, inside the time for that size. A longer set still clears the room.

Questions

Is it free?

Yes. It is free in the browser, with no download and no sign-up needed. Coins are for fun and can never be bought.

Is today's room the same for everyone?

Yes. Today's room is one 5 by 5 grid, from the date. Practice rooms are your own, and they get bigger as you clear them.

What earns three stars?

Darken the room with the fewest lamps, inside the time for that size. Extra lamps still clear the room, for one star. Pause stops the clock.

Can I play on a phone?

Yes. Tap a lamp to flip it. Undo sits under the room, so it never covers a lamp.
