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. Download now and light up your first board.
