How does the pack builder work?
Everything happens on your device. When you press Generate, your browser creates each Mosaic grid from the pack seed, solves it to make the answer key, and lays the pages out as a PDF. Nothing is uploaded and there is no account. Four 5×5, 6×6, or 7×7 grids share a sheet. Two 8×8, 9×9, or 10×10 grids share a sheet. A 12×12 or 15×15 grid has the sheet to itself. Tick Large print if you want one big grid per page. Every size from 5×5 through 10×10, and the print-only 12×12 and 15×15, comes in easy, medium, and hard. The range is Easy → Hard. 12×12 and 15×15 are for print only. Each puzzle prints with its number and seed, so answers line up even when you keep them in a separate PDF. The same seed and settings always give the same puzzles. Use Copy share link to send a class or a friend the exact same pack, or press shuffle for a fresh set.

About these Mosaic packs
Print a Mosaic (Fill-a-Pix) pack and solve it with a pencil. Some cells show a number from 0 to 9. That number counts the shaded cells in the neighbourhood around it, including the numbered cell itself. A corner neighbourhood has four cells, an edge has six, and a cell in the middle has nine. A numbered cell may be shaded. The digit stays on the page. A blank cell has no number. Shade cells so every number matches. A dot means you already know that cell stays empty. The answer key fills the shaded cells, keeps the numbers readable, and does not print dots. Each file is a black-and-white booklet. Puzzle pages show the numbers. The answer key starts on its own page. Packs cover 5×5 through 10×10, and also print-only 12×12 and 15×15, each at easy, medium, and hard. The starter badge reads Easy → Hard, because every shipped size has all three difficulties. A 5×5, 6×6, or 7×7 sheet holds four puzzles. An 8×8, 9×9, or 10×10 sheet holds two. A 12×12 or 15×15 sheet holds one. Tick Large print for one big grid per page. Seeds are fixed, so the same download always has the same grids. Each single pack has eight puzzles, and the starter pack has 24 puzzles, one of every size and difficulty that ships, including the print-only 12×12 and 15×15 grids. The daily puzzle is 8×8 medium.
