light every corner
A dark room of stone. Set lanterns so their glow reaches every open tile โ but no lantern may shine upon another.
ยทTap an open tile to set or lift a lantern. Its light streams down the row and column until stone stops it.
ยทTwo lanterns must never see each other along an open line.
ยทA numbered stone must touch exactly that many lanterns on its four sides.
ยทWin when every tile is lit and every rule holds.
