Lamplight · A practical starting point

Lamplight: actual running game, showing the board and controls — The game’s own board and controls. The points below refer to these mechanics.

The rule to keep in mind

Lamplight is an Akari / Light Up logic puzzle on the Keep the Light night shell. Hang lanterns so every stone in the courtyard is lit. A lantern lights its row and column until a plinth or hedge blocks it; lanterns must never light each other; a numbered plinth says how many lanterns touch it. Forty handmade courtyards from 5×5 to 10×10, each proven to have exactly one solution, plus a seeded Daily.

Start with the constraint

Start from numbered plinths with only one legal neighbour set.

Make one useful change

A lantern that would light another lantern is always illegal — the game shows the conflict in red.

Keep a way back

Empty corners often force a lantern or an empty mark.

Play today’s Daily Courtyard for one seeded puzzle shared by everyone.

Controls and a safe pause
