Puzzle rules
The Mosaic Matrix
Treat each merged colored shape as one logical cell and every unmerged square as one cell. Fill the grid with 1–9 so each row, column, and outlined 4×4 block contains every digit once. All logical cells of the same color must also contain 1–9 once.

Complete rules
Goal: Complete the Mosaic Matrix with the digits 1–9. Rules: - A merged colored shape is one logical cell: every physical square in that shape shares the same value. - Every unmerged square is one logical cell. - Counting merged shapes as single cells, each row, column, and outlined 4×4 block must contain the digits 1–9 exactly once. - All logical cells of each color across the grid must also contain the digits 1–9 exactly once. - Given digits are fixed.
