Evenglow on iPhone: today's puzzle with lamps placed and 9 rooms still dark
Real capture from Evenglow.

Overview

Tap an open cell to place a lamp; it lights its row and column until it reaches a wall. Light every cell, never let two lamps shine on each other, and give each numbered wall exactly that many lamps.

A new puzzle arrives every day, with a streak calendar to keep, plus practice puzzles at four sizes. Solving earns Glow, which lights up the rooms of a house.

Free to play with ads: Remove Ads, a one-time purchase, turns off the ads between puzzles, and Evenglow Plus also adds unlimited hints. No account: progress stays on your phone.

Features

Exactly one solution
Every puzzle is generated on the phone and checked by a solver to have one answer, so logic always gets you there without a guess.
A daily and a streak
One new puzzle a day. Missed a day? Open it later from the streak calendar (on Android, after a short ad unless you have Remove Ads or Plus).
A house that fills with light
Glow from solving lights 35 furnishings across 6 rooms. It is cosmetic and never changes the puzzles.
Practice at four sizes
From 6×6 to 11×11, as many as you like. The first hint on each puzzle is free.

What it does

  1. Tap an open cell to place a lamp. It lights its row and column until it reaches a wall.
  2. Light every open cell, never let two lamps shine on each other, and give each numbered wall exactly that many lamps.
  3. Solve the daily puzzle to keep your streak, play practice puzzles at four sizes, and spend the Glow you earn lighting up the rooms of a house.

Who it's for

Players who like one calm logic puzzle a day, with extra practice puzzles when they want more.

Questions

Is there always one answer?

Yes. Every puzzle has exactly one solution and can be solved by logic alone, without guessing.

How do hints work?

A hint removes one wrong lamp or, if none is wrong, places a missing one. The first hint on each puzzle is free. Later hints on the same puzzle may play a short video ad first.

Are there ads?

Ads between puzzles come only after practice puzzles, never after the daily puzzle. Remove Ads is a one-time purchase that turns those off, and Evenglow Plus is a subscription that also adds unlimited hints.

What is Glow?

Solving puzzles earns Glow, which lights the rooms of the house. It's a collection and never affects the puzzles.
