Light Up: Logic Puzzle

💡 Classic Light Up logic puzzle: light up every white cell, place bulbs to match the numbers, and never let bulbs shine on each other.

A game of pure logic — no luck, no hidden information. When you're stuck, the answer isn't a guess; it's the move you haven't seen yet.

🎮 How to Play

• Place a bulb — light spreads through its entire row and column.

• Black cells block the light.

• The number on a black cell tells you exactly how many bulbs must sit next to it.

• No two bulbs may ever shine on each other.

• Light up every white cell to win.

✨ Key Features

• Hundreds of handcrafted puzzles, from gentle warm-ups to expert grids

• A logic-first hint system: understand the "why", not just the "where"

• A clean, minimalist board built for deep focus

• Play at your own pace: offline, no timers, no pressure — just enjoy the puzzle

🔢 Numbers never lie. A 3 wants exactly three bulbs beside it; a 0 wants none.

When the last dark cell lights up, it's because you reasoned your way there.

❤️ No countdown rushes your next move. Brew a coffee ☕️, pick a quiet evening 🌛, and let the board shut out the noise of the world — every cell you light brings a moment of calm.
