How to play Keep the Light

Tap Light the lamp to make your first glimmers. Spend glimmers on helpers (oil lamps, polished lenses, foghorns, lifeboat crews and harbour lights) that keep the light shining for you. Upgrades double what each kind of helper does.

Keep the Light is about keeping watch. Like every Littleby game, your lighthouse keeps earning while you’re away, normally for up to 12 hours. Here, three night-watch upgrades stretch that to 16, then 20, then a full 24 hours, so you can check in just once a day and miss nothing.

When the light is strong, hand over the watch to the next keeper and start fresh. Every logbook you fill stays on the shelf, making the light 6% stronger each, for good.

Keep the Light is free, needs no account and saves your progress in this browser. You can back it up or move it to another device on the Save page. It is an original game made by Littleby, an independent studio.
