Idle clicker game

Phones and computers

Lamp Oil is an idle clicker game that plays in the browser on phones, tablets and computers, for one player.

Light 40 lighthouses with a lamp you click and twelve keepers and lamps, from a wick trimmer to a great lens. Each one you buy costs 14% more, and every 200 seconds a 20-second storm makes clicks worth seven times as much. Time away pays half rate for up to an hour, and the end card shows your time to light the coast.

Tips

Storms cut your lamps to 70% while they last, so the clicking you do in those 20 seconds is what makes a storm worth having.
Brass crank adds 2% of your light per second to every click, so once the lamps are strong, storm clicking scales with everything you own.
The ×2 upgrade for a keeper needs 10 of that kind and the ×3 for the first four kinds needs 40, so bulk buying unlocks more than its own light.

When does a lighthouse light up?

Lighthouse k comes on when your lifetime light passes 40 × 1.72 to the power k, so each one needs about 72% more than the last. Spending light does not set you back, because the milestones count everything you have ever made, not what you hold now.

Is there a prestige or reset loop?

No. Lighting all 40 lighthouses is the ending, and the end card shows how long the coast took along with your fastest time. Afterwards you start a new coast from nothing; the fastest time is the record worth chasing on a second play.
