The Lamp

Two cells ahead are lit, and a wall stops the lamp.

Loading game…

The Lamp is a small deterministic puzzle about a light that is also a path. The lamp illuminates the cell ahead and the cell beyond it, and a wall stops the ray. You may only step onto a lit floor. After every turn or step, a watcher moves into the first lit floor beside it, in the order up, right, down, left. Reach the door while it is lit. If the watcher enters your cell, you lose.

Controls: Turn left, turn right, or step forward into the light. Restart begins again.
