About Lightbulb

Lightbulb is a clicker game set in a universe where light and darkness are in conflict. You click buttons to turn the light on or off alongside other players, and your choices affect the world in real time.

Light and darkness

Turning the light on or off shifts the balance between hope and darkness. Light reveals secrets that darkness conceals, while darkness hides dangers that light does not face. The game follows a day-and-night cycle based on real time.

Achievements

The game has achievements to unlock.

Frequently asked questions

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
