About Lantern Lights

Lantern Lights is a calm logic puzzle. A grid of lanterns is partly lit and partly dark, and you want every one glowing at the same time. It is a light-switching puzzle, solved with a little logic.

The twist is that a tap flips the lantern you touch and the ones directly above, below and beside it. There is no clock, and every puzzle can be solved. Choose a 3 x 3, 4 x 4 or 5 x 5 grid.

How to play

  1. Tap a lantern. It flips between lit and dark, and so do its neighbours to the left, right, above and below.
  2. Keep tapping until every lantern is lit.
  3. Tapping the same lantern twice puts everything back, so nothing is ever stuck. Use Undo to take back a press.
  4. On a keyboard, use the arrow keys to move between lanterns and press Enter to flip one.

Mitsy's cosy tips

Friendly hints for Lantern Lights

  • Work along one row at a time, lighting the row above before you move down.
  • Watch which lanterns change, not just the one you tapped.
  • Aim for the dark ones in the corners first. They have fewer neighbours.
  • Mitsy's tip: if the board looks like a tangle, undo a few presses and start the row again.

Frequently asked questions

Simple answers for a calm play session

Can every puzzle be solved?

Yes. Each puzzle starts with every lantern lit and is jumbled only by real presses, so there is always a way back.

How does the honey work?

The game works out the fewest presses that would light everything from where you started. Matching it gives three spoonfuls, up to one and a half times as many gives two, and anything more gives one. Ten spoonfuls fill his jar.

Is my best score saved?

Yes, on this device only. Your scores and honey stay in your browser, and nothing is sent to us.

Do I need to download anything or sign up?

No. It runs in your browser, with no accounts.

What kind of puzzle is this?

A light-switching logic puzzle. Each tap flips a lantern and its neighbours, so you plan a few taps ahead. Every grid can be solved.
