{"product_id":"16-grid-klotski-sliding-block-puzzle","title":"16-Grid Klotski Sliding Block Puzzle","description":"\u003cp\u003eThis beautifully crafted 16-grid Klotski puzzle features 15 smooth-sliding numbered blocks arranged within a sturdy 4x4 frame with a spacious empty slot for strategic maneuvering. The objective is simple yet profoundly engaging - slide the blocks in sequence to rearrange them into numerical order or create specific patterns, providing hours of screen-free mental stimulation. Unlike cheap plastic versions, our puzzle uses laser-cut 0.4-inch thick wooden tiles that glide effortlessly along the grooved tracks without sticking or jamming, while the non-toxic water-based finish ensures safe handling. The satisfying tactile feedback and muted \"click\" of moving pieces create a meditative, stress-relieving experience, making it equally suitable for office breaks or classroom brain training.\u003c\/p\u003e\n\u003cp\u003eMaterial: Plastic | Packaging: POLY BAG\u003c\/p\u003e\n\u003ch3 style=\"margin:20px 0 8px 0;font-size:16px;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable
