Play Lanternline
Play LanternlineThe game opens on its own full-screen page and runs entirely in your browser — nothing is uploaded, nothing is installed, and your browser's back button returns you here.
How it plays
Every tile is already on the board. You only turn them. The lantern on the left sends a pulse along whatever copper currently connects. If that path reaches the beacon on the right, the line is lit and the next board runs hotter.
Heat fills while you think. Pause freezes both the pulse and the heat bar. An overheated board ends the run. A later line is the same idea with less time.
A run is two to five minutes. Your best score stays in this browser, on this device. There is no account, leaderboard, or sign-up.

Details
The pulse is the proof
You do not guess whether a route is closed. The light either travels the copper or it stops at the break.
Heat is the clock
There is no move limit. The board cooks in real time, so a clean rotation beats a perfect plan that arrives late.
