Lantern Keeper (Demo)

A storm put out the great lighthouse, and the keepers of the little islands fell asleep.

You carry the last lantern. Turn brass mirrors, split the light with glass prisms, and send warm amber and cool blue light across the water to wake every keeper.

In this free demo

• 12 handmade islands, from a single mirror to a finale that uses everything you've learned.
• Prisms that split one beam into two.
• Two colours of light. Some keepers wake only to amber, some only to blue, and twilight keepers need both.
• Coloured glass that lets only its own colour through.
• No timers, no fail states. Undo as much as you like, and ask for a hint whenever you're stuck.
• A par for every island if you want a challenge. Every par is the true fewest-moves solution, checked by computer.
• Plays on desktop and phones. Tap to turn a mirror, or use the keyboard.

Controls

• Turn a mirror: click or tap it. Keyboard: arrow keys to choose, Space to turn.
• Undo: Z · Reset: R · Hint: H · Island map: Esc · Sound: M

Bolted mirrors are fixed in place. Rocks stop the light. Light passes straight through other light.
