About this game

Lampwise is a calm logic puzzle with simple rules and real depth.

Place lamps on the grid until every white cell is lit.
• A lamp shines along its row and column until it hits a wall.
• Two lamps may never shine on each other.
• A numbered wall touches exactly that many lamps.

That's all. Three rules, and boards that range from a two-minute warm-up to a 13×13 Master grid that takes real thought.

WHY LAMPWISE
• 600 levels in 5 tiers: Easy, Medium, Hard, Expert, Master
• Every board has exactly one solution and can be solved by logic alone. No guessing.
• A new daily puzzle every day, free for everyone, with a streak to keep
• Hints that point out a wrong move or show you the next forced lamp
• Mark cells with dots, undo freely, and pick up an unfinished board later
• Works offline. Dark, easy-on-the-eyes design.

FAIR PRICE
The first 10 levels of every tier and the daily puzzle are free. One payment unlocks everything.
No ads. No subscription. No accounts. No tracking.
