SHARD PUZZLE — Where Broken Becomes Beautiful Every piece of glass tells a story. In Shard Puzzle, beautiful shapes shatter into irregular geometric fragments — and it's your job to piece them back together. SHATTERED GLASS PUZZLES Each level presents a target shape — circles, hexagons, diamonds, and unique random polygons — broken into gleaming glass shards. Drag each shard from the dock and place it precisely where it belongs. The pieces shimmer and catch light as you move your device, creating a stunning visual experience. INFINITE LEVELS, GROWING CHALLENGE Start with simple 4-piece puzzles and progress through increasingly complex challenges with up to 50 shards per form. As you advance, target shapes grow larger, pieces become smaller, and snap precision gets tighter. Every level is procedurally generated — you'll never see the same puzzle twice. CALMING AMBIENT EXPERIENCE Shard Puzzle is designed for relaxation. Soothing procedurally-generated ambient music accompanies your play, with gentle chord progressions and warm reverb. Toggle the music on or off at any time. Perfect for unwinding before bed or during a break. FEATURES - Infinite procedurally generated levels — every puzzle is unique - 5 forms per level with diverse shapes and random polygons - Glass shard visuals with device-reactive shimmer effects - Calming ambient soundtrack generated in real-time - Multiple save slots — share your device with family and friends - Auto-save — pick up exactly where you left off - Combo scoring system — place pieces quickly for bonus points - Golden puzzle rewards every 5 levels - Hint system to guide you when stuck - Clean, minimal interface designed for focus PROGRESSION Level 1: 4 pieces — learn the basics Level 5: 14 pieces — shapes get interesting Level 10: 24 pieces — real challenge begins Level 15: 34 pieces — expert territory Level 23+: 50 pieces — master class Take a breath. Pick up a shard. Make it whole again.
