Witches Sudoku — A Charm Puzzle

Nine charms, nine rows, nine columns, nine boxes. Every one appears exactly once in each, or the grid refuses to settle.

How the Grid Works

Read the rules once — the charms will teach you the rest.

1.Every row, column, and 3×3 box must hold all nine charms with no repeats.
2.Tap an empty cell to select it, then tap a charm below to place it there.
3.A charm that repeats in its row, column, or box glows red. That is your warning.
4.Charms already set in the grid are fixed and cannot be moved.
5.Fill every cell with nothing out of place and the grid is cast.

Choose your difficulty, then tap a cell to begin.
