The best shape for mystery mosaics
Hexagons with 6 edges render curves naturally — no jagged staircase effect like square grids. The result looks smooth and professional.
Hexagonal mosaics are the proven format for activity books on Amazon KDP. Consistent, predictable, and easy to color for all ages.
Start free. Upgrade when you need more.
A mystery mosaic is a color-by-number activity where the image is completely hidden. Instead of visible outlines, the picture is divided into thousands of tiny hexagonal cells, each containing a number. Only when you color every cell with the right color does the secret image appear.
Our generator transforms any image — photos, illustrations, AI art — into a printable mystery mosaic page at 300 DPI. Each mosaic comes with a numbered mystery page, a colored answer key, and a color legend. Ready to print on US Letter or A4 paper.
If you publish activity books on Amazon KDP, our mystery mosaic generator saves hours of manual work. Upload your illustrations, choose a KDP preset (8.5x11" or A4), and download print-ready files. Use bulk mode to process an entire book in one click. All output is licensed for commercial use on paid plans.
Mystery mosaics are a hit in classrooms and at home. Kids develop patience, color recognition, and fine motor skills while uncovering hidden images. Choose the "Kids Easy" preset (8 colors, large hexagons) for ages 4–6, or "Kids Detail" (12 colors) for ages 7–10.
