Mirror Lane, a laser puzzle in a yard of mirrors

Why it surfaced

Mirror Lane pairs a playable browser demo with an unusually clear editorial frame: the page explains its rules, constraints, and scoring without pretending to be more than it is. There are no downloads, accounts, timers, or real-money prizes—just line-of-sight planning, growing boards, and a local best score.

A free browser puzzle where players rotate mirrors to guide a beam through walls and into a glowing prism.
