Sliding Puzzle - Customizable

A classic sliding tile puzzle — fully printable, no hardware required. The pieces lock together with parametric dovetail keys that keep them captive in the frame while still sliding smoothly. The frame holds everything together and prints as a single assembly when using the print-in-place setting, or as separate parts if you prefer a tighter fit. The front face of every puzzle features an emoji of your choice, split across all tiles so the image only becomes clear once the puzzle is solved. Because the icon is pulled directly from your system's emoji font, only emoji characters are supported — regular letters and symbols will not render correctly. A good starting point is something bold and recognizable: 🍕 🐉 🌍 🎃 🦊 ❤️ or similar. If your chosen emoji looks rotated or off-center, use the Rotate Text option in the Customizer (0 / 90 / 180 / 270°) to dial it in — different fonts place their glyphs differently, so a quick rotation often fixes the alignment.
