Light every white square. A lamp shines along its row and column until a wall. No lamp may shine on another, and a numbered wall touches exactly that many lamps.
About Lamps
Lamps is a free daily logic puzzle from Mind Loft. Place lamps on a grid of white squares and walls until every white square is lit. A lamp shines along its row and column until it meets a wall, no lamp may shine on another, and a wall with a number on it must touch exactly that many lamps.
It is a light-placement puzzle, the family sometimes called akari. Every board has a single solution you can always reach by logic, with no guessing. Two lamps that see each other turn red, but a lamp that is simply in the wrong place is never flagged, and a clean solve scores a perfect 10 with the daily leaderboard decided on the clock.
A new board drops every day at midnight Eastern: 7×7 early in the week, 8×8 from Thursday, and a 10×10 Sunday Edition. No app, no signup, play free in your browser. More grid logic: try Duet, Hedge and Plot.
