Light Up puzzles that relight a harbor town
The lights have gone out in a little coastal village and you are the new lighthouse keeper. Every Light Up puzzle you solve relights one lamp, street by street, until the lighthouse beam sweeps the bay again.
Every puzzle after the first teaching board has exactly one solution, reached by deduction. A solver checks each one before it ships, and difficulty comes from the techniques a puzzle needs, not just its size.
Twelve chapters climb from Harbor Steps through Fisher's Row, Market Square and Chapel Hill up the Cliff Path to the Lamp Room. Each solve switches on another window, lamp or string of lights.
A fresh daily puzzle for everyone at midnight Pacific, a streak with room for the odd missed day, and a weekly lighthouse challenge of five puzzles.
Check shows what is wrong without solving anything, and it's free. Hints escalate gently: a nudge toward where to look, then one ruled-out cell, then one lamp, each with the reason why.
No lives that refill on a clock and no locked levels: the whole campaign is free. Ads wait until you have played for a while and never interrupt a puzzle in progress.
Swap tap and long-press, mark cells with dots, undo freely, or switch to the high-contrast Chalk board. Play offline, in eight languages, and keep going in Free Play and Endless Harbor after the campaign.
Tap a dark cell. Its light shines along the row and column until a wall stops it.
A number on a wall says exactly how many lamps touch it. Two lamps may never shine on each other.
When every open cell glows, the puzzle is solved. Solve it without hints for a Perfect star.
Each solve turns on another light in town. Finish a chapter and a whole street comes back to life.
Tap to place a lamp · long-press to mark a dot · mistakes glow red the moment they happen.
